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. Oregons primary was a votebymail 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 shes well qualified. I think she understands families in this country, and what they need. Partly because of hillarys comments on coal, i think especially in Eastern Kentucky i think thats going to be a big deciding factor. And even people that i wouldnt 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 hes worth more than 10 billion, with annual income of 557 million. Hes refused, so far, to release his tax returns. Well 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. Its 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 dont 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 trains 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 statesponsored 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. Its 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, whos 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 countrys Supreme Court has ruled its unconstitutional to ban samesex marriages, but not all mexican states have legalized the practice. Racial segregation is getting worse in americas public schools. The Government AccountabilityOffice 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. Well 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 thats claimed nearly 200 iraqis lives. The deepening divide in the democratic base. Muslim students speak out as they struggle to fit in. Why higher Graduation Rates dont 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 citys 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, burnedout 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. Theyre 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 theyve 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 its 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. Thats 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 iraqs ability to fight isis in the north, especially as the military pursues a new offensive to retake mosul, the nations second largest city. For the pbs newshour, im 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 states 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, were having this conversation because its 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 its troubling what happened in las vegas. Then you had Bernie Sanders put out a statement saying its defiant. He said he doesnt support this but he continued with his statement of particulars saying hes not being treated fairly. Then we had harry reid, the leader of the democrats in the senate, decry that sanders hadnt 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 wasnt 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 fools 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 didnt get their people out. They didnt 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 whats to come in philadelphia in july . I know a lot of people dont 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 were 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, theres 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 shouldnt forget that. Shes 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 hes 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 weve 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 thats where shes focusing on . I think its a question of depth as opposed to breadth in this sense i dont think this has anything to do with policy, what we saw in nevada and whats going on across the country among the Bernie Sanders supporters. Sanders tapped into something in this country, theres no doubt. You can call it antiestablishment. You can say that its millennials getting involved and wanting to make change, but what we saw in nevada and what i think youre 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 its unleashed. I think you see that Bernie Sanders now doesnt 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. Im not sure hes 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. Im 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 wont know that until late july. Sreenivasan how long does it take for them to bury the hatchet . Theyve been pretty intense over the past few weeks and months. Its not just one convention. They can say, were all good, lets go ahead and attack donald trump. Its going to take some time. Hes not going to turn on a dime and have the Bernie Sanders supporters say, were 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 wasnt the nominee, if Hillary Clinton turned out to be the nominee, they would vote for donald trump in november. Thats 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 its 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 socalled protest against the aknownment of Hillary Clinton. Now its become more real as he did better than people thought he would do, as hes 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 hes being cheated. Thats not what happened in nevada, no matter
