a neol offers a new path for former child soldiers in janda. david brooks andathan capehart on robert mueller breaking his silence. and much more. ff nawaz: president trump has called himself "taan." he has said he "likes tariffs," and he's said he likes to use them. but even so, few knew what was toming last night when he issued a surprise threaexico, the u.s.'s largest trading partner. yamiche alcindor has the latest, and more on the president's plan has stirred up concern in thisme country, andxico. >> alcindor: immigration policy through trade tariffs. that's president trump's latest idea to stop illegal immigration on the southern border with mexico. in a tweet late thursday, he announced that starting on june 10, the u.swill impose a 5% tariff on all mexican imports. he said, "the tariff will gradually increasentil the illegal immigration problem is

remedied." today, at a news conference, uexican president andres m lopez obrador responded. >> ( tranated ): we will not fall for any provocation. we will act prudently. we will act with respect for the authorities of the united states, with respect for president donald trump. we have to help so migrants doen nor the united states illegally. but we also have to do itec reng human rights. >> alcindor: this comes as the trump administration seeks to ack down on a surge of central american migrants in recent months. according to u.s. customs and border protection, nearly 11000 immigrants were apprehended in april, the highest monthly total since 2007. and an average of 4,500 people a day have illegally crossed the border or arrived without documents in t past three weeks. u.s. immigration authorities say over 80,000 people are currently in custody. today, white house press secretary sarah sanders defended the tariff threat. >> the number one duty that the president of the unid states

has, is national security, and to protect americans. the president has been crystalth clea we have to take action. we have to step up, and we have to do more to secure our borders. >> alcindor: white house officials y the tariffs would start at 5%. they would then increa to 25% by october if mexico does not pacrease border crossings. tariffs would imct all mexican imports, including produce and cars.e, meanwhhere is bipartisan opposition to e tariff plan. senate finance committee chairman chuck grassley said in a statement, "trade policy and border security are separate issues. this is a misuse of presidential tariff authority, and counter to congressional intent." house speaker nancy pelosi criticized the plan. in a statement, the california democrat said president trump was "sowing chaos over theer bonstead of delivering solutions." it's a concern shared bythers, like laredo mayor pete saenz. he said the proriposed s would hurt his border city. >> it's going to be a huge challenge.

our position here is that it's not going to help us. ultimately, it will be the consumer who is hurt, o will ultimately feel the true impact of this. >> alcindor: t president's move faces opposition in the business community, too. the u.s. chamber of commerce said today the tariffs would not solve the border crisis, pad they would instead, "b by american families and businesses." >> nawaz: and yamiche joins me now. latest on this. yamiche, these tariffs, if imposed, would have an undeniable effect economy, on u.s. consumers. what is the administration saying about that? the administration is essentially saying americans might have to bear the burden of some of these tariffs, but that it's really mexico's fault and not america's al fault. mika otsuka said why should americans have to pay more for avocados, refrigerators, car when it's really a mexican issue and an immigration issue? his response, the american economy is already being

negatively impact by illegal immigration and, also, americans are also paying the price of illegal immigration the important thing to note here, the american government isn't giving mexicolear goal post-s. it's not saying if immigrations and apprehension dpos down beyond 5% we'll be able to re-think the tariffs, instead they're ying we just want the numbers to go down. but here are specific ways we'll make sure you feel the pain of our astronauts you are not doing azenough. >> n you reported there is bipartisan opposition to the plan. we've seen stateo lawmakern both sides all day to this. other than the white house or the administration, who support? th >> the president and the trump administration are on an island of their on on the issue of tariffs. this has been a rare situation where you have republican senators goig statement after statement saying they disagree with the president's move on this. the republicansea havey stuck by the president on issues of healthcare and immigration. we saw republicansers?

from ohio, iowa, saying you're putting the livelihood of our farmers and car-makers at risk here. the president isaying this is the best thing i can do because my back is against the wall because i see a crisis. 80,000 people dyin cusif those numbers actually bear out to be true, those numbers are really, really high. >> nawaz: and they are taxing the system in unprecedented way as you have been reporting. it's worth mentioning the u.s. is in the middle of aes negotiating pr on a separate matter, what we're tawlg calling the new nta, what they're calling the u.s. m.c.a., how does this affect that. >> nawaz: themirump stration says these are twoish shoes. when mika otsuka was asked how would thismpact the trade deal, he said, they're two different thin, don't talk about them at the same time lawmakers opened hill don't sit that way. ernst said this is a trade issue

and we believe it will stifle its ability november rethrough co. people are saying the trade deal is supposed to replace nafta. the president ran on this. it was a keyampaign promise and that might be slowed down and the president is trying to procedural moves to try to force congress to vote on moves without a trade deal in september. that's a lot to happen. >> nawaz:e'll see what happens next. >> yep. het's take a closer look at what mexico can do, andotential economic ripples, with ambassador john feeley. he served as u.s. envoy to panama from 2016 to 2018. and over his 28-year state departnt career, he held senior posts throughout latin america, including in mexico. he is now a political analyst for univision, and joins us tonight from bogota, colombia. ambassador feeley, thank you for being with us. i want to ask you, now, obviously this isn't the first

time president trump has tried to apply pressure to mexico act to do more. what has mexico been doing, if anythingto address the stem of migrants that have been going through their country, and what more can they do before june 10th? >> you know, it's a great question because this is not the first time the president h sas usctions or tariffs. he has said many times before that i'ma tariff guy, i'm a sanction guy. the fact is tashat mexico actually done quite a lot and has been doing quite a lot. you know, we're a a net zero immigration with mexicans right now, meani there are more mexicans returning to mexico than there are going to the united states, whethercu unnted or documented for just regular cross-bored travel. what they've done is they've actually hardened their border at their southern border with guatemala along the rio, in a boarder crossing called taptual

la, and they've crossed tens of thousands of central americans so there is not a lot they can do before june 10. >> nawaz: we have tariffs that could be put in place in the months. what would be the affect of the tariffs on the u.s. economy and trade beeen the u.s. and mexico? >> sure, well, on the mexican economy, it's incredibly worrisome, our supply chains, mexico, united states, and canada are incredibly linked. the united states is the numberd one oftination for 80, 85% of mexican exports. soon as these tariffs go into effect, american importers are going to start to bay 5% up to more by october if the president is not happy with the results. what that means is american importers may now have to make the decision, do i stop importing from mexicans? that obviouslyhouse a ve

negative effect on industry. or do ontinue to poirmt from mexican exporters a tnd pass costs to the american consumer? i think in the short run, wi thint will happen is the supply chains are so independent grrktsd whether vehicles, electronic assemblage, the agriculture products that come from mexico, that importers won't be able to do anything to change that, whether or not they pass along the 5% cost by june 10 is a decision at tan the amerrivate sector is going to have to make, but the key point here is it's aricans who actually pay the tariffs, and that's one of the reasons why many of us believe tha the president has put himself and his ucmca asou were just speak about sort of in the middle of a circular firing scwawrd and yelled fire. >> nawaz: sthe president i trying to use the tariffs to force an action from mexico. would a 5% to 15% tariff have

enough on affect on mexico that would force them to take some additional actions? >> well, let's take a look at this. from my own perspective, if the united states has not been ablee om slow outflow of central american migrantsg through mexico to the united states, i don't know what it is that makes the presidenha believet mexico can miraculously do it. they have stepped it up quite a bit, but obviously not to his satisfaction. you know, take a look at the response from president andreas, almost middle easy he drafted a hio-page letter and appealed to president trump'er angels, if you will, gave them almost a sievics lesson sayi that statue of liberty shouldn't just be an empty symbol. the mexicans really don't have the ability to put up a wall. it's a porous border along central america. they have been cooperating and

it's clear that want the mexican presidt doesn't want aight. he dispatched his foreign minister twashington and ll meet with secretary pompeo next week. i have to be honest, i don't i t know, but i strongly suspect that sectary pompeo and i know his staff were blindsided by this. they had no idea this was coming. so i think the few days is probably -- for secretaryo pom to prepare as much as it is for the foreign minister ofo mex to prepare. >> nawaz: i've seenirsthand the impact on the u.s. system from tin flux of families and children that are coming in and the u.s. has been taxed in unprecedented ways, it has not responded to the taxation, and as a result a lot of these families and children are suffering as we heard earlier in the show. we hrurd from the administration that these are desperate times and desperate times call for dperate measures. we only have a few seconds left, but i want your response to

that. the administration is saying they're doing everything they can to try to stem the floof people. whawhat do you say t that? >> i would say why don't you, instead of putting tariffs on, take the $87 billion tax these tariffs whether represent to the american consumers if they go into effect, and send down 3,500 instead of 350 immigration judg c. that way yn process these cases almost middle east. instead of setting up detention facilities, set up extraditionnary port rooms down there so they can processhe. these desperate people from central america are n qualified under asylum law and that's what they're asking for and t allowing tho stay. i think there are other better ways to have do this than uses apples and oranges, take what is a trade mechanism and tool and apply it to a migration issue that is undeniably difficult.

nobody denies that humanitarian crisis along the bored, but it is my opinion that the crisis has been aggravated by mathe er in which the trump administration has decided to use onlyarrots and sticks. if we got more judges down there, if we expanded e processing, if we were able to use other facilities down alonge the b to be able to not to hold these people indefinitely but torocess them expeditiously, i think you would have a much better resolution ih e current situation. >> nawaz: sticks and not carrots as well. john feeley, thanks for joining us from bogota, colombia. thank you very much for your time. >> nawaz: how do you recover from a brutal war? as uganda struggles to reconcile its violent past, education offers a glimmer of hope. special correspondenfred de sam lazaro reports on one effort to teach former child soldiers.

welcome to you both. david, robert muellee his silence, we have finally heard from him. i want to ask you, though, because the conversation about impeachment continued on the democratic side. nbc's been updating their lis of how many democrats, how many members of the house are supporting an inpeople. inquiry. 53 last time i checked. last week you said speaker pelosi was right to slow walk the prosessmentszo you still believe that based on what we've heard? >> a whole week later i still believe that because democrats have a reasonably atactive esidential field and if they spend their entire early election season fighting for impeachment, it will d aract from thd give what donald trump wants fighting congress. republican support for donald trump s now at a tie and the more they go to impeachment, the more solid's thathere that will be. so there's no way to get republican votes in the senat h so you cane the impeachment harings and they would be a good idea e the rule of law but it won't go anywhere. >>awaz: a couple of quick

sound bieth, key moments from robert mueller and attorney general barr that we heard. >> if we had had confidence that the president clearly did not commit a crime, we would have said so.we id not, however, they can a determination as to whether the president did commit a crimeul. >> we have reached a conclusion. the opinion says you can'tre indict adent while he's in office, but he could have reached a decision as to whether it was criminal activity. >> nawaz: jonathan, you wrote in your column this week muellea life more difficult for trump and democrats. why? >> more diffilt for president trump because if, say, special counsel mueller does go to the ll and does testify and only says what's in the report, just that quote tha you had there from the special counsel mueller alone is damaging and if he reads what is finther dow the report, page 2 of volume 2 of the mural report, if you have it at home, it goes on to say

that, you kw, we have a lot of stuff here, but because of the olc memo, we didn't even broach the subject of whether the president committed a crime. we're not t even goin go there because, if we charge him, and t we can't bringim to trial, we can't indict a sitting president, well, it's unfair to the president because you charge him with a crime, but then he doesn't have an avenue of venue to defendimself and clear his claim, so that's why tholc memo says you can't endiet him while he's a sitting president but you can do it once out of officeecause he has th possibility to defend himself. >> nawaz: speaker s pelod she wants an iron-clade case before moving forwards that an unreasonable goal? >> i don't think it's unreasonable and i thwik i'm h david on this, most people have not read the mueller report and won't read the mueller

report. in order for them to know what's in it the democrats whether through the committee process or through the beginning of an impeachment inquiry,hey will have to learn it by having nstnesses come up and testify, having special c mueller come up and testify and, again, if he only reads what's in the report, it will be news to the american people, and the american people have to bebr ght along in this process to so that they're not blindsided and think at congress is just doing something to hammer at the president, instead o to david's point, standing up for the rule of law in this country. >> nawaz: david, do you think hearg from mural and barr this week changed anything? >> maybe it did in that, asjo than said, a lot of people have erroneous views of what's in the report a lot of republicans do, too. i'm reminded of the phrase i can tell it to you but i can't listen for you. we can tell you what's in the oport but not all of america watches "newshour reads newspapers.

>> nawaz: shocking to me. so when he gets on tvnd actually gives a voice, it wiaches a broader audience. whether any minds be changed if they go through the process as jonathan describes, it will ggast the past couple of years of political history where no mindsere changed by anything. >> nawaz: president trump was overseas. thereas a report, navy officials confirmed, that the white house actually requested hiddtary officials keep the u.s.s. mccain while trump was there visiing troopn the japanese port. the president said he didn't know anything out it but he said it was well meaning if someone put forward the request that there's a picture of mccain and president trump visiting with theroops. david, there are a lot of concerns voiced by a lot of people about the it politicizan of the military. do you see those concerns? >> if i would trigger donald trump if he saw john mccain on the back, i beliee it says something about the white house

culture. i believe donald trump didn't know. shows how the staffers behave. th iwhite house staffers a love with the president and they react and want to get his love. but here it's fear. it's i don't want to do anything that will upset this volatile man at the top, so some staffer said, i don't want to create a negative, so we'll sweep the e --in thing out to hav to h out of the way, south a description of the white house b culture driv his tweets and angry reactions more than the desire to serve anything positive. >> nawaz: you think they're reacting preemptively. >> yeah, i don't want to get on the bad side of the boss. >> nawaz:hat did you think about that, jonathan? >> i thought it was small, pett shameful and utterly predictable. what we have here is a well -- the president in his own words said or whoever did this was well meaning, and at you have here is an administration and a president whos triggered by a war hero, a former priner of

war, the 2008 nominee of the republican party for president an elder statesman, up until his dying day, erand even a his passing, the president still cannot resist taking a dig at senator mccain, whether he knew about the covering up of the name on the ship esise the point, but he was asked the question before getting on marine one, even then he couldn't resist hammering the late senator mccain for casting the deciding vote that maintained obamacare. this speaks to culture of the white house but speaks to a larger issue about the man sitting in the oval office. >> nawaz: david, it's worth mentioning that used to be sacred space, right? you wouldn't impugn the memory of a former senator, former p.w., yet as jonathan mentioned, he said i'm not a fan of mccain, he killed

healthcare for republicans when asked about this, is that sacred aace now gone? >> we've hot of sacred spaces, a little small island of sacredty, if that's a word. mccain auld got under his skin, wecan imagine the reasons, the manliness, and trump has machismo, and john mccain was definitely a macho man and a genuine macho man, ha li out in pursuit of honor. so it would be natural that hed wot under trump's skin. >> nawaz: i want to ask you guys about another storyhat caught attention this week. we d't often get to lk about the census here. a man named thomas hoffr passed away last summer. hidaughter discovered hard drives he left behind that show he played a key role whether or not to add a queionbout citizenship to the census.

this man wasde cond an architect at gerrymandering, verywi good d district lines to the republicans advantage. when you heard that story, jonathan, what did you think? >> you know, when it comes to this particular story, it's one of those things where, especially if you're a perso of color, it's like we know this is happening but we don't have the evidence, or you will hear the errant commt from a legislature, like the one in pennsylvania a few years back. wul say we've done this so we can deliver pennsylvania to mitt romney, 2012, republican presidential nominee, but what was on those hard drive it's in writing, like we can see with our own eyes or atst lhe lateneshoffler' daughter saw wir own eyes, what her father planned and what in his mind went into a justice department legal briefing and, now, the supreme court is going to make

some sort of decision on these very questions. >> nawaz: there was som specific language i want to point out for someone not following the details, basically hoffler said if we want to draw the lines to work to republicans advantage, we want to draw them around voting age citizens. we have to havehe census to get the data to redraw the lines. there's a straight line there. did that s?prise y >> not really. we just didn't know it was there. if you have aned estrang daughter, delete your hard shive becausereleased them. but the second thing is the gradual erosion beeen two sets of institutions in our public. li sometimes some things are the things we fight over the issues, but some things are justlehe of the game that make it fair. so it's like in baseball, we hit doubles or he hit singles, but try not to move the strike zone from batter to batr and what's happened is that distinction has

been erased and the rules thatai make it are now fair game for ustomanipulatetohelpur own side and that's happened in the senate, drawing the lines. what's striking is the shamelessness of it. there are's always a level of some people csh through all moral standards and whatever we can get away with is what we get away with, and there's sort of a boyishelight in that, the ngought i'm doing somethi wrong here didn't even seem to be in the parts of the reporting i read about those papers. >> we don't get to talk about the census. it only comes around every t years. but to remind people of what's at stake andhy the question matters, fill in the context for us, why is this so important? resources. down t by knowing how many people are in the country, there are people at the federalevel, the state

level and the local level who turn to census dtoata etermine how many people live in my community, in my district, in my jurisdiction, and how much money will i need, how many people will nd to help or defend. so the fact they're trying to narrow who gets ttao p in the census or not narrow because it's not narrowing w par takes in the census, but by putting a citizenship question on the census, the impact might be to scare away people from participating which will then skew the results. you can have, say, you know, a town of 100,00ut0 people, b if you put the citizenship question on the csus, you could scare away maybe a quarter of those people, and that skews ttyhe visibif legislators, of public officials, to helping their community. >> nawaz: less than a left, whoever thought the census

could be a controversial political matter? >> the terms are where tarhe dos go. ik's always controversial. it doesn't seem a ridiculous question in the abstract, we ask that question when we go to lea the country, but the fact that the question has never been asked on nsthe seems to be pretty persuasive that they don't need to do it, and just switching results fromr the all the census data we've had over the last x number of years. >> nawaz: a case to watch. david brooks, jonathan capehart, thanks so much for being here. >> thank you. >> nawaz: they may hav this earth millions of years ago, but they still inspire wonder. and now, the dinosaur bones at the smithsonian museum of natural hiory have some new digs. the fossil hall was a multi-ll n dollar renovation that took four years.

it's now complete, with more than 700 specimens, multimedia and interactive displays, set to open in a week. william brangham got a sneak peek, and he is here now with an inside look at the dinosaur's new home. >> brangham: after a 66 million year wait, this seven-ton tyrannosaurus rex may finally have gotten her prey: takingon down a sevenriceratops. discovered in montana in 1988,s thise of the world's most complete t-rex fossils, and it's sse centerpiece of the new david h. koch hall of s at the smithsonian's national museum of natural historin washington d.c. it's just one of more than 700 artifacts on display in the newly-completed hall, set to open next week after a four year, $125 million renovation. but the exhibition is about much more than fosss. the exhibit is called "deep time," which is how scientists

describe the 3.7 bilon year story of life on earth. describing previous mass extinctions and changes to the climate, showing ancient amals and their habitats, along with present-day environmental issues, the exhibit tries to drive ho the connections between our ecosystems and life's evolution, and how lessons from the past might help reguide a sustainable futu. siobhan starrs developed "deep time," and is its project manager. she says dinosaurs arethe start. >> this story about how, literally, our footprint today is written into the stories of be past. so, as you journk into deep time, you can see the same types of things happening on the planet that see happening today, written in the rock, written in the fossils. g d it's a great way to start unpacking and openat book. >> brangham: this is the first major renovation of the famous g isil hall since its open 1911.

one of the most important updates was to the hall'snd architecturengineering.e starrs says iginal designers didn't consider the extreme weight of dinosaur bones. most people think of fossils as dried bone and those are quite i light, bake it, that's not the case. >> no fossils are actually rock. that's the process of fossilization. all of therganic matter in the bone is replaced by rock, so, they're actually quite heavy. >> brangham: to help accommodate kee weight of the fossils, special metal br were designed to support each individual bone. they fit togher like a puzzle, and it makes each bone easily removable, so pieces can be accessible to researchers without dismantling the whole skeleton. su other paleontology halls, fossils often arorted from wiring in the ceiling, but to maintain and emphasize the hall's original architecture, they anchored all the fossils to a new steel frame that stretches beneath the floor. >> brangham: pauline dolovich is the lead architect f the

redesign. >> it's a beautiful, glorious space. and we didt want to take, kind of that beautiful center, and so we found a way to tell this story through this chronological sweep, and then also allow people to flow and kind of live underneath the skylight. >> brangham: all of the support structures and exhibit materials are made of custom, state-of- the-art fire-safe material. it's to ensure these priceless relics would survive the kinds of fires that consumed notre dame and brazil's national museum. the museum was also careful to design the new hall with what's called universal accessibility. >> we're designing forally every visitor who walks in the door, and every visitor is uniq. and they're bringing with them their unique understandings of the world and their unique ways of navigating a museum. >> brangham: for example, here, you're encouraged to touch fossils. literally laying your hands on million-year-old specimens. there's a mobile app available

for visitors that may be visually impaired. even games in the "deep time" exhibit have this inclusivity focus. this one traces the ancient origins of our modern bodies, and has a gender-neutral mai character. this inclusivity is also visible in theeople who helped bring the hall to life. back in 1911, not a single woman was on the design team. today, more than 50 women helped resear, develop and create the exhibition. all of the project's team leaders, and all the writers, are women. the museum says there are more women volved in "deep time" than any other exhibit in the institution's history. paleo-ecologist kay behrensmeyer is the head of the fossil lab a the natural history museum. she says having so many women working on an exhibit like this is important-- not just for her field, butor science more broadly. >> it's very important for there

to be opportunities for all the young women, like myself a long time ago, who are interested in science and want to pursue it, to have the way open to em as much as possible. and they need mentors, they need people to support them. >> brangham: another way the new hall idifferent? "deep time" doesn't shy away from addressing climate change and the looming global extinction of plant and animal species. nor does it shy away from acknowledging the role humans play in driving those crises. like in this mock coal mine, where visitors can learn about why coal is called a "fossil fuel," and how burning it is warming the planet. >> humans are in charge of the future, and finding the balance with the processes that have leme before.

that's an incredourney. >> brangham: in the past, critics have blasted museums, including the smithsian, for accepting money from the koch brothers, a duo who made their fortune from fossil fuels and then funded groups that try to deny climate science. whether or not the museum'sge focus will asshose critics remains to be seen. the museum told the newshourha that donor no input whatsoever in the content of eehibits. the team behind "dtime" hopes that having a greater understanding of the deep past will help visitors understand the role they play in determining the earth's future. the david h. koch hall of fossils, "deep time,opens saturday, june 8. for the pbs newshour, i'm william branghamin washington, d.c. nawaz: now to our "newsour shares." it's graduation season-- the time of year when politicians, artists, and other leade impart sage advice, and some
