Epicenter of the outbreak where a hard hit population is facing significant barriers to care. Many of my friends ask me, you know, why are you working in atlanta . Everybody works internationally. And i feel like we have a third world epidemic, in some ways, here. Ifill all that and more on tonights pbs newshour. Major funding for the pbs newshour has been provided by some say its a calling. Some say they lost someone they loved. Many say its to save lives, as many and as often as possible. Theres 100 reasons why someone becomes a doctor, but at m. D. Anderson, its because theres nothing and we mean nothing we wont do in making cancer history. Lincoln financial is committed to helping you take charge of your 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. Ifill attorney general Loretta Lynch urged americans today to bridge the divide between police and the communities they serve. She spoke as the president attended a service in dallas for five officers killed by a sniper. Lynch testified at a house hearing, and said stopping violence must be a rallying point for both police and minority groups. It is my hope that as we all look at these tragic incidents that we will take the opportunity to draw closer to each other, to have the Difficult Conversations about race and policing in this country, involving all sides, involving all issues and points of view. Ifill lynch also faced a battery of republican questions about the investigation into Hillary Clintons email use. She defended the decision not to charge clinton, but refused to discuss details of the investigation. Woodruff Hillary Clinton finally got the endorsement today that shes been waiting for from primaryseason rival Bernie Sanders. The vermont senator appeared with clinton in New Hampshire and promised to help defeat Republican Donald Trump in november. Well hear what each had to say, and look at what todays moves means for the Democratic Party, later in the program. Ifill in south sudan, the capital city of juba was quiet after a ceasefire took hold. At least 272 had been killed in five days of fighting between rival factions. Meanwhile, the United Nations reported at least 36,000 people are seeking shelter at u. N. Sites and other locations. And embassies and aid groups began evacuating staffers. Woodruff at least 22 people were killed in southern italy today when two commuter trains collided head on, at high speed. It happened on a single track line between two towns in the region of puglia. Rescue workers searched through mangled wreckage, looking for survivors and dozens of injured. And, the italian Prime Minister interrupted a trip to milan. translated after this very brief greeting to you, ill go back straight to rome because of the train crash. And i have ordered an immediate investigation into what happened. I think absolute clarity must be made on this. We will not stop until we understand what happened. Woodruff officials said they wont be sure of the final death toll until a giant crane can pull the wreckage apart. Ifill back in this Country HouseRepublican Leaders confirmed there will not be a vote on gun control legislation until after the summer recess. Majority leader Kevin Mccarthy said it will wait until they return in september. Party leaders have been unable to round up enough votes for their bill to ban people on the terror watch list from buying guns. Woodruff and a big day on wall street the Dow Jones Industrial average reached a record high, gaining 120 points to close at 18,347. The nasdaq rose 34 points and the s p 500 was up 15, adding to its record close yesterday. Ifill still to come on the newshour president obamas call for healing at a Dallas Police memorial, will Bernie Sanders supporters follow his lead . China doubles down on its claims in the South China Sea, and much more. Woodruff dallas mourned its dead today the Police Officers cut down by a sniper. The occasion was an interfaith memorial service, where president obama offered reassurance and a summons to build a better country. It was a moment to honor the five officers who died in dallas. And, to speak to a nation on edge after days of bloodshed, protest and racial tension its as if the deepest fault lines of our democracy have suddenly been exposed perhaps even widened. And although we know that such divisions are not new, though theyve surely been worse in even the recent past, that offers us little comfort. Faced with this violence we wonder if the divides of race in america can ever be bridged. I understand how am feeling but dallas im here to say we must reject such despair im here to insist that we are not as divided as it seems. Woodruff the ceremony took place at the meyerson symphony center, minutes from the site of the sniper attack that erupted during a peaceful protest, last thursday night. Five seats were left open, Holding American flags and police caps, in tribute to the slain policemen. And despite the fact Police Conduct was the subject of protest. Despite the fact that there must have been signs, or slogans, or chants with which they profoundly disagreed. These men and this department did their jobs like the professionals they were. Woodruff the sniper Micah Johnson told negotiators, during a standoff, that he wanted revenge for Police Killings of black men, including last week in baton rouge and st. Paul. Those killings sparked widespread protests, and the president today urged each side to understand the other. When all this takes place more than 50 years after the passage of the Civil Rights Act . We cannot simply turn away and dismiss those in peaceful protest as trouble makers or paranoid. We also know that so much of the tensions between Police Departments and minority communities that they serve is because we ask the police to do too much. And we ask too little of ourselves. Protestors you know it. You know how dangerous some of the communities where these Police Officers serve are. And you pretend as if theres no context these things we know to be true. Woodruff the president had cut short his trip to europe to attend the service. He was joined by the first lady and Vice President and mrs. Biden, as well as former president george w. Bush and his wife laura who make their home in dallas. Most of us imagine if the moment called for that we would risk our lives to protect our spouse or a child. Those wearing the uniform assume that risk for the safety of strangers. They and their families share the unspoken knowledge that each new day can bring new dangers. But none of us were prepared or could be prepared for an ambush by hatred and malice. The shock of this evil has still not faded. Woodruff hundreds of others attended the tribute as well. Among them dozens of Law Enforcement officers from galveston county, texas. A local judge paid for a bus to bring officers on the 300mile, predawn trip. In the end, the president lamented he had spoken to too many Memorial Services during his time in the white house, and he appealed to americans to look deep into their hearts. And if we cannot talk about these things, if we cannot talk honestly and openly not just in comfort of own circles. But with those who look different or bring a different perspective, then we will never break this dangerous cycle. In the end its not about finding policies that work. Its about forging consensus. And fighting cynicism and finding the will to make change. Woodruff after the service, the obamas met privately with officers wounded in the attack, as well as the families of those killed. Funerals for the slain officers begin tomorrow. Ifill after winning 13 million votes, 22 states, and raising 200 million, vermont senator Bernie Sanders formally stepped aside today, throwing his weight to Presumptive Democratic nominee, Hillary Clinton. Then both turned their focus to donald trump. It was everywhere emblazoned on the campaign stage, and all of the signs stronger together, the Clinton Campaign motto. But today, it took on an unmistakably altered meaning, as Bernie Sanders and Hillary Clinton joined forces for the first time. I have come here to make it as clear as possible as to why i am endorsing Hillary Clinton. Ifill the announcement came in portsmouth, New Hampshire, the state that handed sanders his first democratic primary victory, and set up the protracted battle for the partys nomination. It is no secret that Hillary Clinton and i disagree on a number of issues. At the democratic Platform Committee, which ended sunday night in orlando, there was a significant coming together between the two campaigns and we produced, by far, the most progressive platform in the history of the Democratic Party. Ifill sanders did not get all he wanted in the proposed platform, but now, it does include a plank calling for tougher regulations on wall street, language supporting a 15an hour federal minimum wage, and stronger words on climate change. Today, sanders called clinton far and away the best candidate in november. Clinton, in turn, appealed to his supporters. Im asking you to keep working in the weeks, months, years ahead. You will always have a seat at the table when i am in the white house. Ifill the event also allowed the former rivals to form a united front against a common foe republican nomineein waiting, donald trump. While donald trump is busy insulting mexicans, muslims, and women, and African Americans and veterans, Hillary Clinton understands that our diversity is one of our greatest strengths. Trump and his cronies are trying to pull the wool over our eyes, let them give us same failed policies. Ifill in response, the Trump Campaign fired off press release after press release, many of them contrasting sanders past statements about clinton with his endorsement today. One trump attack took aim at clinton for the former secretary of states past involvement with the transpacific partnership, a proposed trade deal that sanders strongly opposes. Clinton repeated today that she now opposes the t. P. P. As well. Still to come details on sanders role at the partys upcoming convention, and in the fall campaign. Will the sanders supporters get on board . We look at that road ahead for democrats with sanders supporter and former ohio state senator, nina turner, and former sixterm vermont governor and president ial candidate howard dean a clinton supporter. Does an endorsement like that, you have been here, on the campaign trail, youve conceded before, does an endorsement like that matter . It does matter. Its actually harder for the supporters to get on board than the candidate, but the candidate leads the way, and this is a big deal. Ifill nin nina turner, a lot of sanders supporters, maybe not in that room, have been saying sanders sold south. Whasold sold out. What are you telling them . When the senator said he would do everything he could to defeat mr. Trump and part of that promise begins with today. I agree with the governor, it is definitely hard for supporters and probably harder than the candidate, and yes, all over twitter and my direct messages, texts phone calls, there are people who support the senator who are very disappointed. There has to be a grieving process, a space for sanders supporters to digest this because his supporters, people like me and others, never wanted this day to come. We always wanted senator sanders to be the nominee, so yes, there is a lot of hurt going on out there. Howard dean, how do you bring the hurting to a place that helps the nominee . Bernie had a huge influence on the platform. So for an issues point of view, most to have the sanders supporters have gotten most of what they want. That will help a lot. Second of all, sanders will do vigorous campaigning because this platform is a platform bernie likes. So over time, i think these wounds do heal. I think not only did most of pi supporters support john kerry enthusiastically, a lot of my staff went to work for john kerry, and it was tough. It was a bitter primary just as this one has been. But you have to do whats right for the country in the end and whats right is Hillary Clinton and whats wrong for the country is donald trump. Ifill Hillary Clinton in 2008 decided to concede one week after barack obama clinched the nomination. This took a little longer. Did senator sanders take too long to endorse . Absolutely not. Everybody has to do this at their own pace and with their own supporters in mind. I think bernie because bernie had such an influence on the platform, i think thats enormously helpful. He needed that extra time. The platform changed, more concessions than most expected and i think that will bring supporters on board. Ifill nina turner, did the platform change enough for you and does it matter what the platform is if the words are different coming out of the candidates mouth . It changed. But for senator sanders continuing to push, we would not have the 15 minimum wage in the federal, abolishing the death penalty, moving marijuana off the federal schedule one. So senator sanders and supporters have a lot to be proud of, but in terms of the t. P. P. , of course, we are disappointed. I was in orlando, i was one of the Platform Committee members, and we fought vigorously to get the Democratic Party to say theyd oppose any vote on the t. P. P. In the lame duck session, but that did not happen. So we still have much more work to do, gwen. Is senator always said its about us, not him, so there has tube folks out there like myself and others who will make sure, to your point, that that platform is not something thats just wonderful words on a sheet of paper, that if a democrat wins the platform is executed on a policy. Ifill you on a platform and we heard Hillary Clinton say she opposes the t. P. P. Why does it matter whether its in the platform . It needs to be in there because we affirm it strongly and if both candidates made it clear they oppose it, senator sanders had the opportunity to push the secretary further left on that, then it should not have been any problem with the Platform Committee members of both candidates voting to make sure that the t. P. P. Was not voted on in the lame duck but that did not happen, unfortunately, but, gwen, it gives us something more to continue to fight for, again. To senator sanders supporters, i want to say this is not the end, it is the beginning and the Political Revolution that he has started must continue because we have to hold people accountable to the platform because a lot of people out there, gwen, are concerned that the platform is just pretty words on a piece of paper. In fairness, there was a third problem, a third party at the table with the t. P. P. , and that was president obama. It would be incredibly unusual to have a very successful president , which president obama has been, rebuked by the Democratic Party platform and i think thats why the t. P. P. Was not in the platform. It would have been seen as a rebuke to the president of the United States whos done, i think, a great job. Hes done a tremendous job, but i dont agree with the governor on that, but, yes, the president has done a great job, but people in the same family can disagree. Ifill let me ask you about disagreeing in the family. You, nina turner, have been calling for perhaps a third party. Is that off the table now . I think both parties could certainly benefit from having another Party Challenge us to do better. I am a democrat, i have been a lifelong democrat, but im not just a democrat to be a democrat. I am a democrat because of the principles and the values we uphold, and if we are the strongest party, we should not fear other of cigs. Ifill howarcigs should nt fear competition. Ifill howard dean, what did Bernie Sanders ultimately bring to this campaign . Bernie sanders in some ways was more of a mover in this campaign than anybody else. The core issue, weve seen it all over the world, and the british just had a very unfortunate vote, where people left behind been globalization are lashing out, and bernie crystallized that and talked about the issues that we have to fix if globalization is going to work and our country is going to be strong. We have to help the people who have been left behind. We have to have better schools, better educational opportunities, better inclusion, better support of working people who arent benefiting from globalization, better tax rules that aid creation of jobs more so than creating opportunities to shift paper around on wall street. Those are the things that bernie brought to the table and those are things in the platform. I think hes transformed the Democratic Party and done it in a positive way. Ifill form
