great to see you both. thanks for being here. before we jump into the conversation it is worth reminding everyone what it was like when these two faced off back in september in 2020 in their first debate. here is a clip. biden: the question is -- trump: you want to put a lot of new supreme court justices. radical left. biden: will you shut up, man? trump: listen, who is on your list, joe? what is on your list? >> gentlemen, i think we have ended this -- biden: this is so un-presidential. amna: why did the biden campaign decide to do this now? faz: there's a lot of reasons. when is that i think they have a sense that they are behind at the moment. you have to re-remind people all about trump's record and engage him, what would you do on the economy? what is your tax plan? those basic questions, they have to do sooner rather than later. they wanted to happen faster so they can bring intensity and energy back into this race among the democratic coalition. amna: the biden campaign has laid out terms, we don't know if

trump has agreed that the terms are no audience, in a tv studio with the moderator, and the mics get cut off after an allotted time. will mr. trump agree to those and stick to those? >> i think he will. he does want to debate. but one of the important things about campaigns and debates in campaigns is managing expectations. i think we have to manage the american public's expectations around whether or not this will be a very substantive driven debate. you see it with the candidates, the way they are framing the terms of it. it has a little bit more of the wwf match quality to it than a real, substantive debate but rump really wants to demonstrate that he has better command, better control over the issues, and he can put joe biden, in his view, on the defensive and also draw the age contrast which he thinks works in his favor. geoff: we will see. in the meantime, there are primary results this week that shows us with the race could look like, some of the issues and where biden then trump could face challenges ahead. if you look at nebraska's results in particular, they show mr. trump the clear winner, 80% of the vote, but nikki haley

pulled nearly 8% and she dropped -- 18% and she dropped out in early march, kevin. she has been racking up sizable numbers in gop primaries since then. 22% in indiana, 16% in pennsylvania. who are those voters and why don't they like mr. trump? >> good question. it's an interesting trendline that she keeps holding this 20% line late in the game. these are conscientious objectors within the republican party. they are not happy with donald trump as the nominee and they our offering protest votes for that. this should be an alarm bell for the trump campaign, but it is not necessarily a deathknell. this is his charge from here on the way through to november. he has to figure out a way to get these voters back. the good news for the trump campaign is the issues that are really motivating these voters are issues like inflation and immigration so he has a message frame that i think is still going to be able to bring these voters back into his fold by election day. the big risk is that they stay home.

amna: mr. biden faces some and with black voters. in particular, there was new numbers from the new york times poll that showed in key battleground states, 60 3% of -- 63% of black voters went for president biden and 23% for president trump but while mr. biden has the clear majority, the analysis showed 23% would be the highest level of black support for any republican presidential candidate since the enactment of the civil rights act in 1964. what does that say about the campaign right now? >> it is not only concerning about black voters. if you look at latino voters in nevada, it is also a concern. young voters, we know that there's some challenges there. biden has to start performing more strongly. i use that word advisedly, strong. at this moment, one of the challenges trump has on biden is the question of who is a strong leader. i think for all of the progressive policymaking you have seen president biden do, it has not been coupled with the politicking. if you look at the fact that the

ftc, the doj take on these big cases, we have people going after airlines, but do you see the fact that this policymaking is taking on powerful interests, that this president is strong to take them on, big pharma, you name them? he's got the agenda but the politicking doesn't match that agenda yet and he has not to -- has to dial up the question of, mi a strong leader with a strong, firm hand on the steering wheel and a vision for the next four years in the politicking, not so much on the agenda, just reassuring that voting base that is largely driven by an economic narrative, that this president is strong and ready to take them on. amna: there's a few senate primary results i want to put to you, too. currently a 51-49 split with democrats in the majority. in maryland, angela beats david in the democratic primary and she's going to face republican governor larry hogan for a seat that a democrat is freeing up. in west virginia, meanwhile, jim

justice, the governor, won the republican senate primary and that will be an open seat, being vacated by joseph manchin. when you look at those results, maryland is particularly interesting. hogan is popular because he has kept things local and focused on his state. he will surely be pulled into national politics and how will he fare there? so it's tough challenge for national democrats when they look at that state. that should be a traditional democratic stronghold but you have a very popular governor, somebody who is seen as more of a moderate, somebody who is focused on a lot of the pragmatic issues that really drive suburban voters that i think are going to be important in that state so i think one of the big challenges for the democrats is how much resources do they really put into that state? and if those resources are going into maryland, are they not going to a state like ohio or a state like montana which is really going to affect the balance of the senate map. i feel like it has advantaged republicans when you look at the overall senate map.

maryland is a traditional tough democratic state. this is going to be a race that is pretty hard-fought but the fact that you're are taking resources from other state i -- from other states i think bodes well for the republicans. >> could democrats lose control of the senate? >> i'm not too worried about maryland. they have a strong democratic contender. i would have been worried if it was david who spent his own money and did not win people over so i think you have a stronger candidate, biden will over perform. beat trump by a lot. in order for hogan to win, he would have to over perform trump, but he will be dragged by his own problems to defend trump's record. it's hard to maintain the majority for democrats but it is lined up where you have a very strong chance to maintain a status quo. if you look at ohio, montana, the races that republicans were hoping for pickups, democrats are in strong positions there. you look at wisconsin. bob casey in pennsylvania continued to maintain strength. ruben gallego, a good candidate who will maintain that seat

against kari lake and i think it is still set up but the fact that you are losing joseph manchin in west virginia, it is not clear where the pickup for a democrat would be this cycle. there's some outside the box candidates and one is in nebraska. dan osborne, independent, unclear who he sides with but a prounion guy, that is my outside the box race. amna: we will take that any time. always great to see you both. thank you. >> thank you. ♪ stephanie: i'm stephanie sy with newshour west. here are the latest headlines. slovakia's prime minister was shot multiple times today in an assassination attempt that has shocked his country, and the region. robert fico had been attending a meeting of his government before the shooting. a 71-year-old suspect is now in

>> this is the pbs newshour from weta studios in washington and in the west from the walter cronkite school of journalism at arizona state university. ♪ geoff: israeli prime minister benjamin netanyahu pushed back today against criticism of his gaza strategy from within his own government. israel's defense minister accused netanyahu of "indecision" and leading israel down a, quote, "dangerous course." the public infighting comes as the biden administration this week said israel did not have a political plan for what's next in gaza. nick schifrin has been following this, and is here with me now. what happened today in israel? it looks like the private infighting has burst into public view. nick: for months the israeli military has been pushing netanyahu to look beyond individual military operations and lay out a political plan for the future of gaza, lay out the goals the military operations that he has ordered are designed to achieve.

today, the defense minister said since october, he and military commanders have been pushing for a plan to have governance in gaza led by palestinians with international actors and that would presumably require the palestinian authority to participate and today, he said that his proposal was never even debated and no alternative had ever been proposed. >> indecision is in essence a decision and this leads to a dangerous course which promotes the idea of israeli military and civilian governance in gaza. this is a negative and dangerous option for the state of israel, strategically, and from a security standpoint. we must make tough decisions for the future of our country, favoring national priorities above all other possible considerations. even with the possibility of personal or political costs. >> those personal or political costs he's speaking about is a direct reference to netanyahu. there are senior u.s. official

-- officials i spoke with who are increasingly concerned that netanyahu is prolonging the war in order to remain prime minister. netanyahu of course denies that and said today his plan was to install gazan families unaffiliated with either hamas or the palestinian authority, but the plan was blocked by hamas. >> therefore all of the talk about the day after, though hamas remains intact, will remain words devoid of contact -- content contrary to what is being claimed. we have been engaged in efforts to resolve this problem for months. there is no alternative to military victory. the attempt to bypass it with this or that claim is detached from reality. there is one alternative to victory, defeat, military, diplomatic and national defeat. nick: detached from reality, he is speaking about his own

defense ministries. netanyahu is worried about his coalition staying intact, members of which have called for the reoccupation of gaza and they were punishing military operation. the national security minister tweeted that gallant failed on october 2, continues to fail now and must be replaced. geoff: is the biden administration view this? nick: they have been pushing netanyahu to accept the palestinian authority to run gaza after the war and that would unlock some of the larger proposals that the biden team has been pursuing especially unlocking air participation in the day after plan. and this week, jake sullivan made another criticism public. he said that netanyahu needed to embrace some kind of political strategy. those goals that he wanted to achieve in order to win the war and u.s. officials tell me that call has not been heeded. geoff: israeli forces are expanding their operation in

rafa. is this the same in -- operation that the biden administration has been advising israel against? nick: officials say the operation so far has been targeted at the border to prevent hamas from smuggling and -- smuggling weapons and people in. officials said they have been doing that, as well as the eastern part of rafah. half a million people from your rafah has fled and he said that "the humanitarian catastrophe that has been spoken of has not been realized nor will it. " we spoke with one of 10 american doctors who has been stuck there in rafah since israeli forces seized the border and closed the border. he served in iraq and he helped save the life of senator tammy duckworth in 2004 when she was injured. that injury cost her both her legs. he said today that conditions in his hospital were both dire and tragic. >> the hardest thing for me is honestly the little children that are coming in with

life-changing injuries. the boy i took care of today that lost an arm, two legs, and part of his remaining hands. i took care of both u.s. military, iraqi military, i took care of contractors, i took care of civilians that were injured in the fight, but the degree and the level of casualties that are innocent civilians, most of my patients have been young children, women, and elderly people that are in their 60's and 70's. geoff: israel blames hamas for the civilian casualties and duckworth says she is appealing to the israeli and u.s. government to try to help. geoff: we appreciate that. thank you. ♪

geoff: inflation cooled somewhat last month, according to new numbers from the bureau of labor statistics. the consumer price index rose at an annual rate of 3.4%, in line with expectations. but overall, inflation hasn't yet come down quite to the levels that many people have been hoping for. our economics correspondent paul solman has the story. paul: the latest cpi data, prices of goods and services did rise last month, but at a slightly slower pace. chris: i think this is good news, particularly because what the federal reserve generally looks at is core cpi, and that's down to 3.6% year on year, which is actually the lowest level since april 2021. paul: core cpi, in other words, explains new york university's chris conlon, everything but food and fuel prices. chris: one of the things that's been pushing up cpi this month has been the increase in gasoline prices. paul: but we shouldn't

necessarily be looking at that. chris: yeah, i think there are a lot of reasons why gasoline prices tend to be volatile, particularly this time of year. that have nothing to do with sort of overall inflation. crude prices are actually been heading downwards. paul: and food prices can be similarly jumpy, for short-term reasons, in contrast to the longer-term causes of, say, the great covid inflation that started all this. though by now, you may be as tired of hearing them and seeing the foage as we are. backed-up supply chain ships due to the stuck-at-home spending spree, stimulus checks, labor shortages, firms hiking prices above their own costs, but today, that's pretty much behind us, according to the harvard business school's alberto. alberto: goods inflation has come down significantly. and we are back to pre-pandemic levels. what still remains is the impact of shelter inflation or rents, which is a category that tends to lag a lot. paul: shelter costs, measured mostly by rents, are more than a

third of the cpi and a clear source of lag, says cavallo. alberto: landlords putting their houses, for rent. they don't have a very good idea of what's happening with supply, with demand. they may test, you know, high rents for a while, and it takes longer for them to internalize and realize that the conditions will require lower rents. and naturally, that, you know, makes the inflation rate take longer to come down. >> go nasa! paul: economists have a phrase to describe this, says conlon, "rockets and feathers." chris: when costs go up, prices go up like a rocket. they go up really fast. and when costs go down, prices fall like a feather. that is, they float to the ground really slowly. paul: but though inflation has swooned since peaking above 9% in 2022, we remain preoccupied. why? stefanie: people tend to associate inflation with a bad economy. we feel like it is eroding our living standards.

paul: harvard university's stefanie stantcheva. stefanie: when i ask people what emotions, you know, do you feel when you see rising prices? predominantly, it's very negative emotions such as anger, fear, and stress. and while they're quite widespread, they're especially concentrated among lower income respondents. paul: and crucially, that's because inflation hits different folks differently, says cavallo. alberto: we all tend to focus on what we call average inflation for an average consumer. but each one of us experiences an actual different inflation based on the products we do buy. we have, for example, low income households consuming a lot more food, than high income households if they're suddenly a lot of inflation in food. the low income households actually experience more inflation. paul: so yes, the data show price hikes tapering, but not for everyone equally, echoes stantcheva. stefanie: we know there's inflation inequality where the basket of goods that people consume will vastly shape the inflation experience. i think this is very important to bear in mind when thinking about people's, you know, stress

responses, reactions, lived experience that might just not well be captured by our official statistics. paul: which may help explain why consumer sentiment sank in may. many americans worried that inflation hasn't dropped fast enough, and could even get worse. for the pbs newshour, paul solman. ♪ amna: today ukrainian troops fell back to defensive lines amid one of russia's largest offensives since the beginning of the full scale invasion more than two years ago. president volodymyr zelensky has postponed all foreign travel, and the u.s. secretary of state announced new weapons deliveries while in ukraine. but as nick schifrin reports, in north-east ukraine's kharkiv, the front is fragile. nick: along the border, ukrainian troops try to hold the

september 2022, military and engineers built defensive lines but because we are so close to the russian border and because of the constant fighting and shelling, perhaps we were not as successful in putting these defensive lines again as -- in as we were in other areas. nick: the russian offensive has captured more territory than any went since february 2022. usn ukrainian officials say russia's goals are to push far enough into the kharkiv region to be able to reach kharkiv city with artillery and to draw ukrainian forces away from fierce fighting in the donbas. inside the city, soldiers go door-to-door to convince villagers to evacuate including natalia, who has been in hiding. >> for five days, we never left the house. we did not see anyone. we were so afraid to go out, we never even opened the door. >> it is pretty hectic and you no, a lot of schilling's -- shelling and it is everywhere. nick: this humanitarian worker with the rescue committee.

the deaths of tens of millions of birds from europe to antarctica. but as william brangham reports, as h5-n1 continues to jump into mammals, most recently into dairy cows, many scientists are concerned that we're not watching closely enough as this virus continues to spread. a warning, this story contains scenes of animals in distress. william: evolutionary biologist michael worobey at the university of arizona is one of many scientists around the world trying to untangle bird flu's latest twist, how and when it spread to dairy cows. michael: the jump into cattle probably took place between mid-november and mid-january, and so we're months into this already. william: and since then, it's spread like wildfire, infecting dairy cows in at least 46 herds across nine states. michael: it seems to be spreading cow to cow in some fashion, but we don't know exactly how that is. for example, it could just be

mechanical transmission as one cow leaves a milking machine, leaves virus on it, and then the next cow comes in. or is this going respiratory like flu does with humans? william: in late april, the usda mandated that milking dairy cows being transported across state lines need to be tested for bird flu. do you think we have got now enough surveillance out there to know what this virus is doing and where it's moving? >> i think we still have a long way to go, honestly. we are still sort of dealing with a pretty limited number of samples from a limited number of farms. and that limits exactly how much we can understand, for example, you can actually figure out, just like we did with covid, you know, the number of people infected is doubling every two days. we still don't know that with cattle. william: but even the initial

discovery that bird flu had jumped species and was now circulating in cows was thanks to a bit of epidemiological work by a handful of veterinarians. >> the main common denominators with the cattle were a sudden decrease in feed intake, a sudden decrease in milk production, variable fevers, variable manure consistency. william: doctor drew magstadt is a veterinarian at iowa state's vet diagnostic lab. he was helping colleagues in the texas panhandle and kansas who were dealing with a bunch of sick cows, but then a new clue emerged. on these same farms where cows were sick, a lot of cats had gone missing, gotten sick, or had died. so you thought we have to check h5n1, the bird flu, because it's been in this area, but you really didn't think that was going to be the case. >> well, yeah and we didn't end up ruling it out, we ended up finding the virus. the intriguing part here is that this virus in cattle doesn't seem to be causing any

mortality. after several weeks, the animals recover, so it's very different from the infection in other mammalian species. william: in fact, unlike cows, this bird flu has been deadly to the nearly two dozen other mammal species that've been infected in this u.s. from a polar bear in alaska to a mountain lion in colorado. to racoons and foxes, many of those animals were likely infected by eating dead animals that were carrying the virus. but by far, the biggest impact here in the u.s. has been on birds. since this strain of avian influenza first arrived in the u.s. in early 2022, brought here by migratory birds, more than 90 million domestic birds, mostly chickens and turkeys, have died or been intentionally killed across 48 states. and unlike previous outbreaks, this variant has affected more wild birds, and spread across a

wider geographic area, crossing down into south america at the end of 2022. dr. vanstreels: i think the alarm really went off when it reached peru, and that's a massive seabird community and we saw ju unprecedented mortality in the seabirds there. william: uc davis' dr. ralph vanstreels is a wildlife veterinarian based in argentina, and he watched as the virus arrived and decimated bird populations, and then made another jump into mammals. an estimated 24,000 sea lions died from the outbreak. it was one of the earliest known mass mortality events from bird flu in mammals. dr. vanstreels: at first, we weren't sure if each of those sea lions was getting infected by eating a bird. but it became pretty obvious pretty quick that this was spreading from mammal to mammal. william: in argentina, dr. vanstreels estimated that the virus killed 17,000 elephant seal pups and an unknown number

of adults, a blow to that population that may take decades to recover. dr. vanstreels: it's definitely very distressing. i can say we've worked with these animals for many years. so we've known these populations, we've seen these colonies. and on the one hand, we are prepared because we expected it. on the other, nothing can prepare you for it. william: earlier this year, researchers confirmed that bird flu had spread all the way to antarctica, primarily affecting birds known as skuas, but so far, antarctica's iconic penguins haven't been affected. dr. vanstreels: but this virus can mutate quite quickly, right as it did when it started infecting mammals, so it could mutate again and start infecting penguins. so we're not quite out of the woods yet. william: and it's that possibility of mutation, where the virus adapts and becomes better suited to spreading from mammal to mammal, that has many on edge. particularly now that h5n1 was discovered spreading in all those dairy cows.

while experts stress it's still very unlikely that this outbreak will lead to the next human pandemic, and government officials say pasteurization kills the virus in milk and dairy products, there are real risks for those who work in close contact with cows. in march, a farm worker in texas was infected, but had mild symptoms and recovered. the cdc says it's monitoring people exposed to infected cattle, but admits that only 33 people have been tested. >> what we have is a situation where the virus, in a sense, has more shots on goal to jump from a related species, mammal like us. and now, people are no doubt being exposed on a daily basis in pretty large numbers. william: worobey says it's a stark reminder that we have not learned as much as we hoped from the covid pandemic. michael: we need to be spending billions more to do things like routinely monitor not the tip of

the iceberg of cattle who are visibly ill, but routine monitoring to just fine, ok, is there something that shouldn't be spreading in this animal species or in humans? and we are still not doing that. william: and with more than 9 million dairy cows in the u.s. alone, getting eyes on where this virus may go next remains a monumental challenge for animal and human health. for the pbs newshour, i'm william brangham. ♪ amna: latino americans make up nearly 20% of the u.s. population, and this year are expected to be a critical constituency for both republicans and democrats in swing states. and yet, as judy woodruff reports, the very idea of latinos voting as a block betrays the diversity of history, culture, and

are trying to come into this country without documentation? sylvia: they must be pretty desperate to walk thousands of miles to to get here and to go through all that agony. but as far as being on the border, i've been down there. i mean, we're 100 miles from nogales, from the border. we're not getting overrun by millions of immigrants. judy: that's not how polo sees it. raf: i think they need to come in legally. a lot of the folks that are coming through, they're not good people. rapists. murderers. and i'm pretty convinced that terrorists are here. judy: when it comes to former president trump, who famously launched his campaign by denigrating mexicans -- >> they are bringing drugs, they are bringing crime. they are rapists. and some, i assume, are good people. judy: he has repeatedly

disparaged immigrants as he calls for more restrictive policies. sylvia: his first comment was that all mexicans are rapists and murderers. am i supposed to have open arms? that's not true. my family is nothing like that, and most immigrants are nothing like that. i'm not going to stand by and let them say mexicans are terrible or, you know, latinos are terrible. that's not acceptable. that is not american. raf: you know, i'm from new york, so i grew up with people like donald. so it doesn't bother me. judy: and do you think he'd be a good president? raf: i think he'd be outstanding. judy: that division reflects one playing out across the country. and while latinos have long been a key constituency of the democrats, recent polling shows that the gap between the parties is tightening, with 44% of registered latino voters favoring donald trump and 52% supporting joe biden.

dr. klar: the latino community is so diverse that we want to look at every group really based on their country of origin more than anything else. judy: samara klar is a professor at the school of government and public policy at the university of arizona. she tells us these differences of opinion should not come as a surprise. dr. klar: so, you know, to say, how do cubans compare with mexicans is almost saying, like, how do canadians compare with japanese immigrants? because you're from two completely different countries, people who come here at different times under different circumstances. judy: she studies how an individual's personal identities and social surroundings influence their political attitudes and behaviors, and says because of common experiences among latinos, she sees less partisan hostility. dr. klar: so for white democrats and white republicans, there's not a lot that really bonds them. for latino democrats and latino republicans, we see linguistic ties. we see religious ties. we see experiences with discrimination. we see experiences as in the

-- as a minority or as an immigrant. judy: so as you think about latinos as a voting bloc now, what should we think about it? dr. klar: well, first, i would not think about latinos as a voting bloc. latinos are an incredibly diverse community of people. we have latinos who come from dozens of countries all over the world. different nationalities, different backgrounds, different histories, different immigration patterns, different immigration eras. it can be a little confusing because it makes it harder to understand voting patterns within this very diverse group of people. judy: at the same time, the sheer size of the latino community hasn't always translated into political power or representation. marie: we're very often not, not made to feel that we fit in. we're not in the school books. we're not in the textbooks. so this is really wonderful representation. judy: marie arana is an award winning author, journalist, and the former inaugural literary director at the library of congress, where we met. in her new book,

latinoland, she has taken on an admittedly difficult task by attempting to cover 500 years of latino history in the united states. marie: even though there are we have a great number of millions of eligible voters, we do not necessarily register to vote. and that is a problem for us. that is a real problem. judy: where does that come from? marie: it comes from the fact that you are prejudiced. discrimination, a sense of not fitting in. and there is this sense that, you know, why should we vote? we're not paid attention to anyway. judy: she believes that during this polarized period in our country, a diverse latino community can help moderate american politics. marie: there is within the latino population itself, we represent diversity within

us because of the many races that we are. and i think in general, we are a moderating force. judy: back in tucson, professor klar says her research bears that out, showing a key difference between most latinos and non-latino white voters. dr. klar: we find that for latinos in arizona and elsewhere across the country, they express much warmer feelings toward the other party. their feelings toward their own party are about the same. so it's not like they're cheerleaders for every party, but there's much less affective polarization or personal dislike between the parties within the latino community. judy: and what is this over here on the left, upper left? 2020? that is true for raf. he says he hasn't let politics get in the way of his relationships. can you talk to your friends who are democrats about your issues? raf: yeah. yeah. we're all educated. we are experienced, successful people that don't need to use short words to express themselves.

judy: you haven't built a wall between your house and the neighbor who is a democrat or a liberal? raf: no, no. we have a bunch of liberals right down the street. [laughter] judy: but sylvia gonzalez andersh prefers to steer clear of politics with her republican neighbors. she told us she has family members who support former president trump, and that she struggles with the fact that other latinos have a more negative view than she has towards new immigrants. sylvia: well, i could get really dark about that. i could really think, well, if you are willing to turn against your own people and pull up the ladder behind you, that means that you have the same traits as you know, somebody that just wants to get ahead at any cost. it's just a lack of empathy, a lack of "i got mine and i don't care if you get yours." judy: it's anyone's guess how this will break in such a hard-fought election year. but what is clear is that both campaigns will be making their

case to the 36.2 million eligible latino voters. for the pbs newshour, i'm judy woodruff in tucson, arizona. ♪ amna: south africa recently celebrated 30 years since its first racially-integrated elections, marking the official end of apartheid and making nelson mandela the nation's first black president. here in the u.s., a south african musical group continues to spread mandela's message of racial reconciliation and healing, while also reminding us that the fight for equality in both nations is far from over. special correspondent megan thompson reports for our arts and culture series, canvas. ♪
