captioning sponsored by newshour productions, llc >> sreenivasan: good evening. i'm hari sreenivasan. gwen ifill and judy woodruff are away. on the newshour tonight: a relentless wave of isis- claimed bombings in baghdad bring the death toll to nearly 200 just in the last week. what's behind the latest spike in violence? also ahead, with the race's finish line in sight, democrats in kentucky and oregon cast their primary vote, but is the party moving further apart ahead of the general election? plus, from military artillery ranges to prisons. a remarkable story of transformation and the unlikely allies of endangered butterflies. >> when i watched the butterflies struggling to come out of their cocoon, it really makes me realize that, yeah, we all do need to struggle to get to where we need to be.

>> sreenivasan: all that and more on tonight's pbs newshour. >> major funding for the pbs newshour has been provided by: >> fathom travel. >> lincoln financial-- committed to helping you take charge of your financial future. >> and with the ongoing support of these institutions: >> this program was made possible by the corporation for public broadcasting. and by contributions to your pbs station from viewers like you.

thank you. >> sreenivasan: kentucky and oregon take their turns on the democratic primary stage tonight. polls have now closed in the blue grass state as hillary clinton and bernie sanders watch the returns. oregon's primary was a vote-by-mail affair, but in kentucky, primary day was more traditional with voters giving voice to the divisions in the party. >> i think hillary stands up for women and children and families, the violence in our country, the gun issue, oh my goodness, so many issues, foreign policy. i think she's well qualified. i think she understands families in this country, and what they need. >> partly because of hillary's comments on coal, i think especially in eastern kentucky i think that's going to be a big deciding factor. and even people that i wouldn't have expected to vote for bernie are talking about voting for him.

>> sreenivasan: republicans also voted in oregon, with donald trump close to wrapping up the g.o.p. nomination. today, he reported to the federal election commission that he's worth more than $10 billion, with annual income of $557 million. he's refused, so far, to release his tax returns. we'll come back to divisions on the democratic side, later in the program. the u.s. senate voted today to let families of 9/11 victims sue the government of saudi arabia, setting up a possible veto showdown. the saudis have threatened to pull billions of dollars from the u.s. economy if the measure becomes law. senators from both parties rejected the warning, and passed the bill by voice vote. new york democrat chuck schumer said it sends a clear message. >> if the saudis did not participate in this terrorism, they have nothing to fear about going to court. if they did, they should be held accountable. it's that simple. and there are certain moral things that should supercede day to day relationships between countries. >> sreenivasan: the white house argues the bill could boomerang,

and expose americans overseas to legal jeopardy. spokesman josh earnest. >> we need to make sure this is- - that we don't overlook the potential unintended consequences of a bill that could put the united states at risk around the world. that is a dangerous proposition and one that the commander in chief i think is rightly concerned about. >> sreenivasan: the legislation still has to get through the u.s. house. it looks as though operator error was a critical factor in the amtrak crash in philadelphia, a year ago. the national transportation safety board officially concluded today that the train's engineer was distracted by radio traffic. the train accelerated to 106 miles an hour going into a sharp curve with a speed limit of 50 miles an hour. it derailed, killing eight people and injuring hundreds. the justice department will investigate state-sponsored doping by russian athletes. "the new york times" reports the focus is on any russian officials, coaches or athletes

who violated drug rules at competitions in the u.s. those who used the u.s. banking system in the process, could be targets, too. it's unclear if russian authorities will cooperate. a move to make young american women subject to a military draft has been sidetracked for now. the house rules committee today dropped a provision that women 18 to 25 sign up for the draft, just as men do. conservatives argued it could present a dangerous blurring of gender lines. the head of the armed services committee, republican mac thornberry of texas, raised questions about selective service overall. >> there has not been a review of whether we need selective service since 1994. and so my strong view is that we need to ask the big questions and figure out whether we need it. if so, for what purpose? what would happen if we did away with it? if we do have it, who's going to be involved? >> sreenivasan: the u.s. has not had an actual military draft since 1973.

the senate today confirmed eric fanning to be the secretary of the army, first openly gay leader of any military service. he was approved on a unanimous voice vote eight months after president obama nominated the president of mexico proposed legalizing gay marriage today. enrique pena nieto signed initiatives to add the provision to the mexican constitution and the national civil code. the country's supreme court has ruled it's unconstitutional to ban same-sex marriages, but not all mexican states have legalized the practice. racial segregation is getting worse in america's public schools. the government accountability office reports black and hispanic children are increasingly concentrated, with few, if any, white classmates. those schools also offer fewer math, science and college prep classes and have higher rates of suspension and expulsion. a separate report today focused on the "state of black america." we'll look at that, later in the program. and, wall street sold off today

on growing expectations of a new interest rate hike. the dow jones industrial average lost 180 points to close just under 17,530. the nasdaq fell 59 points, and the s&p 500 dropped 19. still to come on the newshour: a spike in violence that's claimed nearly 200 iraqi's lives. the deepening divide in the democratic base. muslim students speak out as they struggle to fit in. why higher graduation rates don't equal higher incomes for black americans, and much more. >> sreenivasan: another day of extreme violence hit baghdad today, as at least 77 people were killed and 140 wounded in a series of bombings across the city. william brangham has our report. >> brangham: the capital city's largely shiite neighborhoods were ground zero for this latest carnage. the worst killing came in the shaab district where a roadside

bomb detonated at a crowded marketplace. when people rushed to help those victims, a suicide bomber attacked. >> ( translated ): an explosion took place here killing a woman, her brother and her niece. some other people who came to shop were either killed or wounded. what crime have innocent people committed? >> brangham: it was much the same in the sprawling sadr city district: a car bomb left mangled, burned-out vehicles at an outdoor market, while a suicide bomber targeted a nearby eating place. >> ( translated ): this is the second blast in sadr city. one is here and the other blast was outside a restaurant we are fed up with this violence. the city has been the scene of explosions. >> brangham: in all, bombs ripped through four different locations across baghdad today: shaab and habibiya in the north, as well as nearby sadr city, and the dora neighorhood, on the southern side. they're the latest in a surge of attacks in and near baghdad that claimed more than 200 lives in the last week alone. iraqi officials say isis

militants are using the bombings to try to compensate for ground they've lost on the battlefield. american officials echo that belief. >> the united states strongly condemns the barbaric terrorist attacks in iraq today that deliberately and specifically targeted civilians. >> brangham: in washington, state department spokesman says it's clear the battle is far from over against isis, known in arabic as daesh. >> these attacks are the latest reminder of the danger that this group continues to pose to all iraqis, and the importance of iraqi leaders from all communities to continue to work together so progress against daesh can continue to be made. >> brangham: in all, the baghdad government estimates that isis still controls 14% of iraqi territory. that's down from 40% back in 2014, when the militants made a lightning advance. but as iraqi forces gain ground in the north and west, backed by u.s. air strikes, the new

violence around baghdad has put added strain on those forces. it could open the possibility that army units are pulled from the frontlines of the battle against isis to help secure the capital. any such move could undercut iraq's ability to fight isis in the north, especially as the military pursues a new offensive to retake mosul, the nation's second largest city. for the pbs newshour, i'm william brangham. >> sreenivasan: we turn to the race for the white house. on the democratic side, bernie sanders and hillary clinton will face off in primaries tonight in kentucky and oregon. but over the weekend, clinton and sanders supporters were at odds in nevada at the state's democratic convention, potentially signaling a greater divide in the party. here to help breakdown the divide is susan page, washington bureau chief at "usa today." and from las vegas, jon ralston, host of "ralston live." susan page, we're having this

conversation because it's important. but even just today there were a flurry of communications throughout the democratic party about the tone and tenor of what the candidates should be doing, what their supporters should be doing. what happened? >> we saw the democratic national chairman debbie wassermann schultz saying the campaigns need to accept. this it's troubling what happened in las vegas. then you had bernie sanders put out a statement saying it's defiant. he said he doesn't support this but he continued with his statement of particulars saying he's not being treated fairly. then we had harry reid, the leader of the democrats in the senate, decry that sanders hadn't done more to address this in a serious way. the concern is not just what happened over the weekend in las vegas, the concern is is this a precursor to a divided democratic party as they head into the democratic national conventiona. >> sreenivasan: what happened over the weekend in the great state of nevada, jon? >> it wasn't such a great state

over the weekend? it was a raucous convention. all conventions are raucous to some extent, but the bernie sanders' folks went into that convention determined to cause trouble, because they thought that the state party, which essentially is harry reid, was being unfair to them. they filed a lawsuit beforehand. reid tried to tamp it down, got bernie sanders to put out a unity statement. but that was just a fool's errand. it had no chance of working. and so the problem for the bernie sanders' folks, they had no perspective on this, is they lost. they lost the caucus on february 20th. they managed to flood some county conventions, but they didn't get their people out. they didn't fill out the close to 500 delegate slots for the state convention. they were outnumbered, got overruled in the changes they were trying to make, and the real irony here is this is only over a few delegates that would not have mattered. what susan said is the most important point: how much of a

harbinger is this of what's to come in philadelphia in july? i know a lot of people don't like to think of nevada as some kind of alien world, but i think nevadans are pretty much like people everywhere else. that could be a real problem for the democrats in philadelphia. >> sreenivasan: we were expecting perhaps a contested convention on the republican side, the unexpected to happen, and now donald trump seems to be walking slowly toward what might be a coronation. but this is... what we saw were videos from cell phones of people, bernie sanders supporters yelling, "recount, recount! " in nevada. is this what we're likely to see in cleveland in. >> the divisions are much more serious in the republican party, even though there is no longer any question that donald trump will be to nominee. there are real questions about what does the republican party stand for going forward. he has not been endorsed by the top republican official in the country yet. so there are real divisions in the republican party, but there are real divisions in the democratic party, as well. some of them go to policy.

you know, there's some policy differences between hillary clinton and bernie sanders, but a lot of them go to kind of, who do you want to get things done. do you want the most experienced candidate, that would be, or do you want somebody who describes himself as a revolutionary who will really shake things up? and bernie sanders has captured the energy of this party. hillary clinton has won a majority of the votes in the primaries. we shouldn't forget that. she's very, very likely to be nominated as the nominee at the convention. but bernie sanders is the guy who has the enthusiasm and the energy and especially with young voters, so he's not a force to be denied at this point. i think the clinton campaign is still figuring out how to deal with that and how to emerge with a united party to deal and face donald trump. >> sreenivasan: we've had folks from both campaigns saying thiwill sort itself out. how much of this is structural? right now bernie sanders support esses still see hillary as the immediate competitor whereas hillary has pivoted and sees donald trump as the eventual

competitor and that's where she's focusing on? >> i think it's a question of depth as opposed to breadth in this sense: i don't think this has anything to do with policy, what we saw in nevada and what's going on across the country among the bernie sanders supporters. sanders tapped into something in this country, there's no doubt. you can call it anti-establishment. you can say that it's millennials getting involved and wanting to make change, but what we saw in nevada and what i think you're seeing now is frustration and actor with a process they see as slanted against them and their man, and that is very, very difficult to control once it's unleashed. i think you see that bernie sanders now doesn't think he should control it at this point, because as you may have seen earlier, he put it that defiant statement about what happened in nevada. i'm not sure he's going to be able to control it in july either, even if he is standing up on stage in philadelphia holding arm in arm with hillary clinton declaring unity. i'm not sure he can control it.

the question, though, is how broad is it? i think some of these feelings are very deep, but it is 10% of bernie sanders' supporters, 20%, 30%? we won't know that until late july. >> sreenivasan: how long does it take for them to bury the hatchet? they've been pretty intense over the past few weeks and months. it's not just one convention. they can say, we're all good, let's go ahead and attack donald trump. >> it's going to take some time. he's not going to turn on a dime and have the bernie sanders' supporters say, we're okay with hillary clinton. in other words, in the exit polls a week ago in west virginia, about four in ten of bernie sanders' voters in west virginia said they would vote, if bernie sanders wasn't the nominee, if hillary clinton turned out to be the nominee, they would vote for donald trump in november. that's a number i think probably gets reduced if bernie sanders endorses hillary clinton as enthusiastically as i think a lot of people expect him to ultimately be, but it takes time to persuade people who are now battling with one another that they ought to join forces.

>> how much of it is about the two candidates, as you said, not so much about the policy right now? >> yeah, i do think it's become very personal. you know, campaigns get very intense. i think this started almost as a lark with some people who were supporting bernie sanders as a so-called protest against the aknownment of hillary clinton. now it's become more real as he did better than people thought he would do, as he's won all of these late states. now i do think there is a real anger percolating out there among the sanders folks that, wait a second he's being cheated. that's not what happened in nevada, no matter how they're portraying it. the fact that sanders was unwilling to say, you know, i lost fair and square, and then play into what his campaign out here is saying happened, i think it's a very, very bad sign. and again, i do... i have very little confidence that what he has unleash canned be so easily controlled, no matter how skillful hillary clinton or any

of the rest of the democratic establishment thinks they are. >> sreenivasan: all right, jon ralston from "ralston live" and susan page, thank you very much. >> thank you. >> sreenivasan: next, a look at the growing problem of harassment muslim-american students often face in public schools. surveys by the center on american-islamic relations, a civil rights group, suggest that some 50% of muslim students have been bullied by their peers. one hot-spot has been st. cloud, minnesota: a small city 90 minutes west of minneapolis. john tulenko of "education week" reports on the controversies there and how the school district responded. it's part of our education series "making the grade," which airs tuesdays on the newshour. >> reporter: hafsa abdi, who's 18-years-old, remembers well the day four years ago when she was first bullied for being muslim. >> the last day of by 8th grade

year, school i was just going home and this boy i think he was a year younger than me, he pulled up my hijab. at the time i was wearing a longer one so it was more easy to pull off from the back, and then i also had like a pin to hold it in place and that kind of came loose, and so at the time i was just trying to think of five different things at one time and how to get the pin from stabbing me in the neck, and turn around to see who this kid is. >> reporter: in high school the bullying continued, especially when she and other muslim students would gather to pray. >> mostly the upper classmen, they would come into the bathroom sometimes and start fighting with the somali girls that were trying to wash for prayer and then when it gets reported nothing would happen. >> reporter: what would they say? >> so they'd be like, "oh why are you making the bathroom dirty you stinky somali." or, "you terrorist," stuff like that. or "go back to where you came from." >> reporter: where hafsa comes from is minnesota. she was born here, after her parents fled somalia to escape civil war.

thousands of other east african refugees have also come to st. cloud. changing the face of this mostly white, mostly catholic, small city. >> my job is to make sure that all children, whether it's their children, whether it's somebody brand new to the country, that they have the best tools available to be successful here in america and here within our community. >> reporter: for superintendent willie jett, educating the new arrivals required changes across the board. >> what we've had to do is start from ground zero. you're trying to make sure that all languages in the school are welcomed, you're trying to make sure you have interpreters, you're making sure you're revamping teaching staff and support staff and the way you hold conferences and send messages home. it's not what it was 20 or 30, 40 years ago, not even 10 years ago. >> reporter: but all this change, in and out of schools, has stirred resentment. >> there is a lot of racial

prejudice in our area. >> reporter: at this local coffee shop, the divisions in the community were plain to see. >> they think they're americans, but when our forefathers come over they blended in with everyone else. and these people... >> this is america, they should be talking english, but you walk downtown and they're always talking their language. how the hell are we supposed to get to know them if we don't know what the hell they're saying. >> i've not had a difficulty with the somali community, we talk about ourselves being american but i don't think we're very welcoming. >> reporter: similar tensions had been building in the high school, until they came out, online. >> they would take pictures of us. the one that i can think of that was most popular, there was this girl who was in a wheelchair because she broke her leg and she was in the lunch line waiting and this senior boy who went here last year he took a picture of her and he captioned it, "handicapped and isis too."

and he put it on his snapchat story. and the snapchat story is available for everyone to see, it spread within like 10 minutes and the whole school knew about it. >> united we stand. divided we fall. >> reporter: reaction was swift: muslim students walked-out of st. cloud tech in spring, 2015. reports of harassment emerged in other cities throughout summer and fall of last year, especially after the massacres in san bernardino and paris, and following candidate donald trump's call to ban muslims from entering the country. >> i've had mothers write and say "my heart cries every night thinking about how my daughter might be treated in school." >> reporter: the president addressed the problem at his first ever visit to a mosque in february. >> we are one american family. and when any part of our family starts to feel separate or second class or targeted, it tears at the very fabric of our nation. >> we're come together to make a difference in our school so

everyone feels safe and welcome. >> reporter: back in st. cloud, they've used the year since the walkout to speak out against harassment, by training this specially chosen group of students to go out and begin a dialog with the bullies. >> we're trying to include people and we're not going to sit here and say, "you know your opinion is wrong you shouldn't feet this way and that way about a culture." we're trying to educate them in hopes that they would open up their minds and, i guess, change. >> reporter: and how they'd go about changing minds could be seen in activities like this one, in which the students arranged themselves according to how far they were born from st. cloud. staff member sebastian witherspoon is one of the group's founders. what do you want them to learn? >> difference is ok. if you're from somalia, if you're from duluth as a black male, from robbinsdale, whatever, there is beauty in difference, beauty in coming from different places, having different cultures. that's education to me, having

all these people with a variety of experiences and us learning from that to enrich our lives. >> reporter: students are also organizing a cultural carnival, featuring food, music, and clothing from their home countries. but in some groups they're worries about who'll come. >> the people who don't want to be there are the people who need to be there. >> i mean, i feel like the people who need the conversations aren't the ones who are actually coming. >> reporter: there could be another approach, which the president had seemed to use, and we brought it up with hafsa. hafsa, i'm wondering maybe the better approach would be to educate those bullies about what it means to be an american? >> i do feel like it comes from the stereotype of what an american looks like, so a lot of people feel someone who looks like me can't be an american, because of my skin color or my hijab, and that makes me not an american, so i feel like a lot of people really do need to understand the actual definition of what it means to be an american.

>> reporter: but others in the group weren't so sure. what about the notion of america? >> i feel like we've been teaching what our country was founded on since elementary school. with social studies. with u.s. history. with government. we've been constantly talking about what this country is founded on with liberty, justice, and the pursuit of happiness, but it's not sticking to people. so i think we need to find a different approach to this. >> reporter: so one year from the walkout, how much has changed? >> i have seen muslim people and st. cloud natives on better terms, but it's nothing like super-noticeable. >> there are other students who are stepping up to help, like if a somali kid is walking down the hallway and somebody says something to them, they might step in a say, "hey, that's not funny." and i notice that happening every once in awhile and i feel like gradually, it's changing. >> reporter: it's a start on what's likely a long-term project. in st. cloud minnesota, i'm john

tulenko of "education week," reporting for the pbs newshour. >> sreenivasan: stay with us, coming up on the newshour. the episcopal church's first african american presiding bishop explains why acting like christ would change the nation's politics. plus, an unusual sanctuary for an endangered butterfly. but first, the national urban league has released the 40th edition of its annual state of black america report. it's designed to provide a snapshot of where african americans are relative to whites. according to the most recent report's calculations, across multiple facets of life african americans experience equality at a rate of 72%, compared to white americans who score 100%. here to explain is marc morial, president and c.e.o. of the national urban league. let's start with that 72% number. how do you get there? what does that mean in. >> what it means is if you

compare things like unemployment, home ownership, high school graduation rates, college attainment rates, median income, african americans on average achieve 72% that of where whites are. these are collective numbers. we also do the same comparison for latinos. latinos are at about 77%. whites being, of course, higher. that's based on numbers, based on facts, based on clarity. we report this information every year. this is the 40th year we've done it. we not only report the information, but we also propose solutions. >> sreenivasan: one of the indicators or one of the factors is income inequality, the gap there. one of the largest income disparities that you point out, at least between black and white families, is in the minneapolis metro area. the average household income for

a black family there is just over one-third, 37.8% of the average household income for a white family. how does this happen? >> this happens because the better-paying jobs, the higher-level jobs go to whites, and african americans are stuck in lower-paying jobs. on an overall basis. an we see this glaring disparity in places like minneapolis. it's also present in places like san francisco where there is a tremendous amount of success, a highly educated workforce. african americans are far, far behind. i hope that what this means is in a city like minneapolis or a city like san francisco, they won't sweep these numbers under the rug. they won't pretend they don't exist. and they will recognize and see it as a challenge for the civic business and political leadership of those communities to try to address these disparities. these disparities exist in virtually every major american metropolitan area. it is just a question of to what degree. >> sreenivasan: one

interesting thing you mentioned earlier today is there is actually an era in the united states where african american were considered three-fifths of a person. here you have this snapshot of how african americans are doing over the last 40 years. looking back across this, at income equality, i'm struck by the fact that in 1976 the average black family nationwide earned 59% of what a white family did. now, 40 years later, it hasn't gotten much better. 60%. what's behind the stagnation? >> notwithstanding the political progress, the progress that's been made in terms of high school graduation rates, number of african americans who have attained college and great individualized success, this is a persistent, structural, locked-in economic situation, and i believe, hari, that we highlight it because it defines the pressing challenge of the american future. for latinos and latinos and african americans are almost one-third of the population in

this country, latinos don't fare much better than african americans. this is an important challenge for america's political business and civic leaders to figure out, to concentrate on how to end these persistent economic inequities in the united states. >> sreenivasan: there is a little bit of an up side in some of these numbers. higher educational achievement, that's an movement. 40 years ago 6.. % of black people had a bachelor's degree or more. that's 43% of the number of whites with those degrees. today that percentage is up to 63%. what led to the increase? how is it affecting the black community? >> i think those increases were the result of policies that began in the 1960s and the 1970s. the pell grant program, affirmative action, and higher education. the desegregation of schools and the focus on educational... improving educational standards. much of what we've done in the educational arena where there's been a focus on civil rights and

economic injustice, if you will, has begun to make a difference. we see it indeed in the numbers. it has not, i repeat, it has not significantly translated into the economic arena. and this is why the main street marshal plan, which reflects our plan to address this, suggests a commitment of a trillion dollars over five years to begin to address some of these deep inequities. it's our effort to say, let's not get bogged down in just an analysis and a diagnosis of the problem. let's also focus and figure on how to change it. now, this is what we also saw in the numbers. from 1963 to 1976, that 13-year period during the years in the war on poverty and at the height of the post-civil rights era, we actually made tremendous change in america. the poverty rate went down. income inequality narrowed.

but then at 1976, it got stuck. and the disparities of 76 have become the disparities of 2016. now, we don't know the effect of the recession. if we had not had the 2008/2009 recession, if, in fact, the challenges or the disparities would be less, we're in the sure of that fact. the fact of the matter is the disparities exist. it presents the challenge for this nation, for our 21st century. >> sreenivasan: all right. you can go online to read the main street new marshall plan so to speak. thanks so much more joining us, marc morial. >> appreciate it. >> sreenivasan: the most reverend michael curry became presiding bishop of the episcopal church last november, becoming the head of one of the united states' oldest denominations at a time of conflict and change.

the church, like most mainline protestant denominations, is also facing declines in newshour anchor judy woodruff sat down with bishop curry to learn how he is leading a church facing these challenges. >> woodruff: bishop michael curry, thank you for talking to us. >> thank you. >> woodruff: congratulations on your position. >> thank you for that. >> woodruff: let me ask you first, how would you describe the place that the episcopal church occupies in the broad religious profile that we have in the united states now? >> the episcopal church probably represents ad many rat voice, a centrist voice in the lidge just landscape. we've historically been able to live with differences. now i think we're seeking to live that out in some new ways to be a church that really can embrace diverse, in the only theological traditions opally -- or liturgical tradition, but

that's the episcopal church and the act cal way at its best. >> woodruff: you're now six months into this position. how has the fact that you are the first black presiding bishop of the episcopal church of the united states, a descendant of slaves, how has that affected what you have been able to do so far? >> certainly that has affected only in the sense that it is a first. beyond that, i have a funny feeling i was probably elected for a variety of reasons. i suspect that my election was a moment of hope, that we could begin to help the episcopal church and episcopalians begin to focus outward in new way, outward in ways that actually share the message of jesus of nazareth, which is fundamentally a message of love god and love neighbor. that's a game changer in and of itself. the various forms and ways we're divided between each other, whether it is racial or

socioeconomic or political or religious or tribal or national or hon and on and on, helping this church to become instruments of god's work of reconciliation in this world. that really does have something to do with helping the world stop living a nightmare and start living something closer to god's dream. and that's worth doing. i have a feeling that's why i got elected. >> woodruff: you've spoke an great deal and preached about social justice in its many different forms. how does that fit into what you see as maybe this developing, evolving vision and mission of the episcopal church? >> scholars, sometimes when they look at the origins of christianity, they often use the phrase "the jesus movement" as a way of describing what jesus of nazareth actually was doing in the earliest days in palestine, that the jesus movement.

in the first and second and third centuries was a movement. of people who gathered around the teachings of jesus of nazareth, and their gathering around and committing themselves to that way of life jesus talked about became transformative for themselves and for the world, and as a result, the earliest christian communities were communities where both slave and free coexisted and lived together, where men and women, where jew and greek or gentile coexisted and lived together. that was the earliest christian movement. and i'm committed to helping the episcopal church become a jesus movement. today that helps the society live up to that vision. >> woodruff: what's the practical effect of that? how would people's lives change vument of that ideally? >> i mean, dramatically. imagine if just episcopalians were practically living their daily lives as reflections of the way jesus of nazareth lived his, loving in the same way

jesus did and does, giving in the same way, forgiving, doing justice, caring, living come park in the lives? i have a funny feeling episcopalians could be transformative both in our interpersonal relationships and in our social and political relationships. what would happen if christians just acted like christians? it would change our politics. it would change our social order. it could change our global community. >> woodruff: do you think our politics needs changing? >> regardless of which side of the aisle you're on, this isn't a partisan statement, imagine our politics if we began to engage each other not from the perspective of my own self-interest, but from the perspective of our interest, the common good, the common wheel. imagine our global politics. imagine our economic relationships. it's world changing. and i happen the believe that the way of jesus of nazareth, i'm not talking about everybody, although that would be nice, but that's not what i'm really talking about.

i'm talking about a way of living that is deeply grounded in the kind of love that is not a greeting card for valentine's day. but that is a way of living in this world and engaging it. >> finally isaiah got caught up like a episcopalian in a baptist church, got caught up in the spirit. >> woodruff: they say that sunday morning is the most segregated time and place in american life. >> uh-huh. >> woodruff: in church service in this country. should that change? >> i think the church can create space for authentic ethnic congregations that minister to a particular need, especially at a particular time. but it must also move into inhabiting or creating space for congregations where people of different races and ethnic backgrounds and sociocommission classes actually come together, because ultimately, i mean, i do pray for the day when those of

us who have the same commitment to follow the considered of jesus of nazareth can actually find that commitment and that in christ there is no east nor west, in him no south nors? north. we can get there. i pray for that day, but i know that between here and there, we have to approximate it as best we can. >> woodruff: we've learned just recently that pope francis is saying that he is open to the idea of a commission to study permitting women to become deacons in the catholic church. what would you say is the experience of the episcopal church that might inform what the catholics may be thinking about. >> when we finally get to the point of saying, who has god called to be a bishop or a priest or a deacon, and we're going to follow that lead-in, what we found over time is, guess what, a priest is a priest.

a deacon is a deacon, a bishop is a bishop. they may be black, right, red, yellow or brown. they may be a republican or democrat. they may be gay or straight, bisexual, transgender. they may be a whole host of things, but they're a priest. they're a bishop, they're a deacon. that's been our experience, not for everyone, but for most of us. and the church has been enriched when all voices are there, when we're all there together, you got a better shot of making it together than we do when we're all apart. so i... you know, my catholic brothers and sisters, you have to make your decision as god needs you. this is how we've made ours, and we have been blessed. >> god has not given up on this world. we dare not give up on it either. and god is not finished with this church. god has worked for us -- god has work for us to do. >> we have a better episcopal

church. i have been in the episcopal church my whole life. we are a better episcopal church because we really are trying to welcome all. >> woodruff: presiding bishop michael curry, thank you very much. >> thank you. god bless you. >> sreenivasan: now to a remarkable story of transformation and the unlikely allies of an endangered butterfly. a recent u.n. report warned some 40% of pollinators-- birds, bees and butterflies-- are at risk of extinction. humans are the driving force behind the decline. special correspondent cat wise reports on a unique effort in the u.s. that leads to more than flowers blossoming. >> reporter: the artillery practice range at joint base lewis-mcchord near seattle washington is not a place you'd expect to be ideal habitat for an endangered species. but it is.

meet the taylor's checkerspot butterfly. ten years ago, this beautiful insect was on the brink of extinction. 99% of it's native prairie habitat in the pacific northwest and british columbia has been lost to urban and agricultural development. the only location it could be found was here on the artillery range. why? well it turns out that bombs actually benefit this butterfly. >> if you're an individual butterfly that has a artillery shell land on you it's bad, but if you zoom out from that small scale impact, and look at the way that the training ignites fires across the landscape, and improves the habitat across the landscape, overall it is likely good for the butterfly population. >> reporter: dan grosboll is an insect biologist at the base who has to be very, very careful when out looking for butterflies amid artillery shells.

grosboll and a team of other government scientists are now working to boost the numbers of butterflies here, but there's only so much they can do when this land is needed for other purposes. >> the base is here in order to support troops training, so that troops are ready to go and fight. the fact that we also can provide habitat for endangered species is a really good thing, but it's important that all of the preservation of endangered species is not borne by the base. >> reporter: so the military sought out help from an unlikely group, who happen to have a lot of time on their hands. on a recent morning, a small team of inmates at the mission creek corrections center for women walked into a greenhouse, known as the "butterfly lab," and quickly got to work. the greenhouse, which sits just

outside the walls of the minimum security prison, was built five years ago with funding from the department of defense. now these women, whose lives have all taken a wrong turn at some point, have become leading experts in the field of captive butterfly breeding. susan christopher ended up here after making some bad decisions to support a gambling habit. now, after going through some extensive training on butterfly rearing, she's fully engaged in a more productive and important endeavor. >> we came up with this diagram so that we could keep our matril-lines separate through our breeding program. the male from this line will get bred to females of this line, so when we continue to move through that circle, so that we never breed the same line to itself. >> reporter: and why is that important? >> for genetic reasons. we want to have as much genetic

diversity, and not have the chance of interbreeding. >> reporter: the women, who are called "butterfly technicians," are raising the insects throughout their multiple life stages, so they can be released back into the wild. it takes a lot of patience, and a loving touch. >> it's honey solution on the q- tip. >> reporter: and they have been very successful. more than 30,000 taylor's checkerspots have been raised for release by this facility and the oregon zoo, which has a similar breeding program. >> i've gone one, two eggs for sure. >> reporter: on the day we visited, cynthia fetterly and jessica stevens were working together on a very delicate project-- harvesting the tiny eggs that female taylor's checkerspots had recently laid. >> the one i just got done finished doing that was in the wild, and we weren't sure if we were going to be getting any eggs off of them because they already look like they've been pretty spent. so getting that big cluster of eggs was really exciting. it's very rewarding, and it's

hard to explain when you can actually help bring back an endangered species. it's very humbling to be able to do that. >> reporter: the butterfly breeding program at mission creek is part of a larger effort in washington state, called the sustainability in prisons project, to connect inmates with science and nature projects while they are serving time. it's a joint endeavor by the washington department of corrections and the evergreen state college. kelli bush is the program manager for the project, and she says the benefits go beyond the prison walls. >> it seems to be changing lives. not just the incarcerated individuals, but corrections staff, and biologists, that everyone involved seems to be feeling good about the work, and the contributions that are being made through these efforts. when the larvae hatch, they'll start feeding on those leaves that it's on.

>> reporter: one of those who is benefiting from the butterfly technicians' hard work is mary linders, a state biologist who has been spearheading efforts to increase the butterfly's habitat, and numbers, around puget sound. she says initially, she wasn't sure how it would be to work with inmates. >> it's very detail oriented work, you really need a lot of consistency in the people that are actually working on it, so it was a risk. but it has proved to be a tremendous success. the folks at the prison have done just a fabulous job of running a top notch facility. >> reporter: linders and a group of scientists and volunteers recently gathered to release captive raised caterpillars in a wildlife area near olympia, washington. and, for the first time since the program began, they were joined by two inmates who had raised many of those insects.

after getting a tutorial from linders about where and how to place the bugs... >> what you're going to do is release these in groups of two to five. you can just brush them right off the lid. >> reporter: ...inmates michelle dittamore and eva ortiz began to release their fuzzy friends, with mixed emotions. >> i feel like, it's a lot like your teenager flying the coop to go to college, and you're just like, "i've literally bathed you, i've dressed you, i've done your laundry, i've packed your lunch." but i have to have faith that there's been so many generations of just instinct bred into these little guys that they're just, they're going to get down there, and they're just going to know what to do. >> reporter: also helping out at the release, carolina landa. landa was released from the correctional facility last year after serving time for a drug offense. but she's now enrolled in the evergreen state college environmental science program-- a big change of direction she attributes to her time spent with the butterflies. >> here is an endangered

species, and the fact that they were saying, yes, we trust you, yes, we believe that you can do this work. that very much played a big factor in me believing in myself, right, to start that path. >> reporter: the combined efforts, of all the various individuals and groups, are paying off: at this release site the butterfly population has doubled since last year to several thousand. and at joint base lewis-mcchord, the population has just been deemed to be self-sustaining, a significant milestone for the species. back at the prison greenhouse, susan christopher says she's learned some valuable lessons from the butterflies. >> when i watched the butterflies struggling to come out of their cocoon, it really makes me realize that, yeah, we all do need to struggle to get to where we need to be. >> reporter: christopher and her colleagues are now gearing up for a busy summer caring for some hungry caterpillars. for the pbs newshour, i'm cat wise in washington state.

>> sreenivasan: and, finally tonight, our newshour shares: something that caught our eye that might be of interest to you, too. in the waters near caesarea, israel, two casual scuba divers made the discovery of a lifetime last month when they spotted a bronze statue. the duo had stumbled upon the remains of a 1,600 year-old roman shipwreck and the largest cache of underwater artifacts found in israel in three decades. they alerted local archeologists who later recovered bronze busts, oil lamps and thousands of coins bearing the faces of roman emperors from the wreckage. and we mark the passing of the world's longest serving symphony musician. bassist jane little first debuted with the atlanta symphony orchestra in 1945 when she was just 16.

little was still performing with the organization 71 years later when she collapsed on stage sunday during the evening's encore of "there's no business like show business." she later died at a local hospital. jane little was 87 years old. plus, tonight on "frontline," a revealing documentary about the rise of islamic state militants. "the secret history of isis" takes a critical look at decisions taken by the u.s. and its allies and how they may have fomented sectarian tensions among iraqis, allowing extremist leader abu bakr al-baghdadi to recruit thousands and take up arms. >> back in raqqa, al-baghdadi was pursuing a new opportunity, the expansion of isis into iraq. >>at this very time that al-baghdadi is building his organization in syria, the baghdad government, the shia government and al-malaki starts

virtually assaulting the sunni homeland. >> in the years since the american troops had left, iraq's prime minister, a shia, had initiated a crackdown on the sunni population. >> the sunni-arab tribes in iraq had become disillusioned with the shia-dominated government in baghdad, so there was widespread disaffection among the tribes. they began to engage in a series of protests against the regime. >> these protests were violently crushed, and in such an environment that enabled islamic state of iraq to rise up out of the ashes and say, we will protect sunnis from malaki. >> it was the moment al-baghdadi had been waiting for. >> where had the sunnies to go? there's only one place they can go? it is that residual of the insurgency that is now run by al-baghdadi.

>> in early 2014, al-baghdadi's forces began the campaign the take iraq. >> the iraqi army, which was built at the incredible expense, i don't even know what the final price tag was, $30 billion, largely by the americans, paid for by the american taxpayer, you know, all their equipment, everything, it all came apart. >> in no time at all they rolled over fallujah, ramadi, then the biggest prize yet, iraq's second largest city, mosul. >> sreenivasan: watch "frontline" tonight on most pbs stations. check your local listings. and later tonight: "point taken" tackles the complex role of the u.s. in the mideast. again, the day's top story, right now cut kentucky's democratic primary race between hillary clinton and bernie sanders is too close to call. results from oregon, the night's other primary, are expected later. clinton is virtually assured of winning the party's nomination, but sanders says he'll take the
