Thank you. Sreenivasan its the eve of the president ial primaries in the Hoosier State. 57 delegates are at stake for republicans and ted cruz is trying to wrestle whatever he can away from his rival donald trump. John yang has our report. You are the problem, politician. You are the problem. Reporter ted cruz went for broke today, trying to pull off a crucial primary win indiana. This afternoon he faced off with backers of republican frontrunner donald trump. I think anyone that wants to be president owes it to the people of this state to come in front of you and ask for your support. And im running to be everyones president those who vote for me and those who dont. We dont want you. Well, youre entitled to your views, sir. And i will respect it. Do the math. You asked kasich to drop out its your turn. Take your own words. Reporter but the words drop out dont seem to be in cruzs vocabulary yet anyways. I am in for the distance as long as we have a viable path to victory. I am competing to the end and the reason is simple. Listen. This isnt about me. It isnt about donald trump. It isnt about any of the candidates. This is about our country and our future. Reporter and Associated Press analysis has cruz trailing trump in the race for the nomination, by more than 400 delegates. Unable to win the delegates he needs to win on a first ballot, cruz is trying to keep trump from locking up the nomination before julys cleveland convention. Trump spent the day making his final pitch in the indianapolis area. Honestly, if we win indiana, its over. Its over. And if we dont, well win it next week, or the week after, or the week after, thats fine because they have no path, whereas i have a very easy path. I mean, well win it on the first ballot. Reporter farther south in evansville, democrat Bernie Sanders was whipping up support. Not just for the indiana primary, but also for his effort to keep his campaign viable until the convention. The way the system works, you have establishment candidates who win virtually all of the superdelegates. It makes it hard to make insurgent candidacies like ours to win. But you know what, were going to fight for every last vote. Reporter Hillary Clinton has a commanding lead in delegates and seemed to be looking beyond the convention. Today she campaigned in kentucky. Here in eastern kentucky, and obviously west virginia, and southeast ohio, appalachia coal has taken a huge hit. Its something that im really worried about because, talk about a ripple effect, it is just decimating communities. Reporter late today, she paid a visit to west virginia. For the pbs newshour, im john yang. Sreenivasan well take a deeper look at the president ial campaign with politics monday right after the news summary. In the days other news, the u. S. Said progress is being made toward restoring a truce in syria. That came as the Syrian Military extended its own, unilateral ceasefire in some areas, including damascus. But violence continues to rage farther north in aleppo. U. S. Secretary of state john kerry was in geneva today meeting with the u. N. s envoy for syria. Kerry expressed optimism, but stopped short of detailing truce proposals. We are working over these next hours intensely in order to try to restore the cessation of hostilities and at the same time to raise the level of accountability that will accompany the daytoday process of implementing this ceasefire. Sreenivasan to that end, kerry who later spoke by phone with his counterpart in moscow said the u. S. And russia agreed to station personnel around the clock in geneva to better monitor a new truce. An Islamic State car bomb killed at least 18 people and wounded dozens more in southwestern baghdad today. Workers used shovels and water hoses to clear debris following the blast. Many of those killed were shi ite pilgrims commemorating the death of a revered eighth century imam. Puerto rico has defaulted on a 422 million bond payment that was due today. Its officials warned the u. S. Territorys debt crisis could soon worsen, without the help of congress. In washington, white house spokesman josh earnest said he hopes this creates a new sense of urgency for lawmakers, to restore puerto ricos debt restructuring authority. Sreenivasan the islands default will likely prompt lawsuits from creditors, and could foreshadow more problems to come when a much larger payment is due july first. Nearly all of detroits 97 Public Schools were forced to close today after teachers staged their latest sickout. They protested the possibility that some of them wont get paid through the summer, if the debt Stricken School district doesnt receive more funding from the state. Todays closure impacted some 46,000 students. Cancer researchers today issued a warning to new england residents who get their Drinking Water from private wells. A study from the National Institutes of health found a correlation between Bladder Cancer and arsenic levels in maine, New Hampshire and vermont wells. Bladder cancer incidence in the region is 20 higher than the rest of the country. The risk is even greater if wells were dug before 1960, when arsenicbased pesticides were common. The person behind the Digital Currency bitcoin may have finally been identified, after years of speculation. Craig wright an australian entrepreneur and Computer Scientist told several News Agencies today he invented the currency back in 2009. Bitcoins allow consumers to purchase goods or services and Exchange Money anonymously without involving banks or other third parties. In an interview with the b. B. C, wright said he came forward with reluctance. I didnt decide, i had people decide this matter for me. And they are making life difficult, not for me, but my friends, my family, my staff. I have staff here in london, i i dont want money, i dont want fame, i dont want adoration, i just want to be left alone. Sreenivasan but several publications have questioned wrights claim. Earlier today, i spoke to andy greenberg, a Senior Writer from wired via google hangouts. He said todays revelation has raised even more questions. This has only gotten hairier as a story. It was unclear at first whether this was a hoax or whether we had found the creator of bitcoin and i think weve only gone further down the rabbit hole. Sreenivasan for our full interview with andy greenberg, visit our website pbs. Org newshour. On wall street today, stocks bounced back after last weeks losses. The Dow Jones Industrial average gained 117 points to close at 17,891. The nasdaq rose 42 points. And the s p 500 added 16. The first u. S.

Leicester city has won the barclays premier league, after overcoming 5,000 to one odds. The foxes finished near the bottom of the league last year. But lost only three times this season, and clinched the title today, when secondplace tottenham played to a tie. Its leicesters first championship in the clubs 132 year history. Still to come on the newshour politics monday a look ahead to indianas makeorbreak election for ted cruz. Then c. I. A. Director leon panetta on the fight against al qa five years after osama bin ladens death. How Warren Buffetts son is helping africa feed itself, and much more. Sreenivasan all eyes are on indiana in the race for the white house. We examine the heightened significance of the Hoosier State in 2016 with our politics monday team tamara keith of n. P. R, and amy walter of the cook political report. So, one of the things we saw ted cruz say in the earlier piece was a viable path to the candidacy, that hes in this till it ends. Does it end tomorrow night for him . I think its already over. I think the race effectively ended last week with the primaries up and down the northeast corridor and donald trump putting up such big numbers. Hes ahead in the polls now in indiana. Hes ahead in california. Its going to be i think all but impossible for him to be stopped before we get to the convention, and even then i think hes going to get the 1237 votes he needs before the convention, i just think the momentum is strongly behind him, cruz never caught on. The stop Trump Movement always had an antagonist, which was donald trump, but never had a protag nighs, which was its biggest challenge. There was never a challenge to voters as to what to support, its always what you can be against. Voters like supporting someone and a winner and now looks like donald trump is a winner. Sreenivasan what about the stop trump folks. Are they in denial . Is it an inevitability . Theyre still working it and ted cruz is campaigning extremely hard. His campaign between his various surrogates, his Vice President ial pick, carly fiorina, they had ten Campaign Stops in a single day. At a are working very hard in indiana but seems like if donald trump wins in indiana after this disarmament pact was announced with john kasich and, really, ted cruz has had donald trump to himself mostly, if he cant win, Donald Trumps going to be able to make a very strong argument, what are you doing if you cant win in indiana . If donald trump is able to win all the delegates in indiana, hed be 85 of the way to clinching. Thats quite a long way toward clinching. Sreenivasan this appliance between kasich and cruz, it was on on a tuesday, off by a saturday. Is it still an . Kasich wasnt campaigning in indiana today. No, he wasnt, but the stop Trump Movement has spent almost as much money on television, the outside super pacs, in indiana as wisconsin where ted cruz was successful. I think voters are desperately looking for this is one to vote for. This idea of voting against donald trump really not catching fire, plus, the one getting the momentum beyond what youre seeing in the polling data is the endorsements. Donald trump picking up endorsements from royalty in indiana. Everybody from lou holtz, the former notre dame coach to bobby knight the former indiana coach, the basketball ring very big in indiana. Sreenivasan shifting gears to the democratic side. Yes. Bernie sanders still fighting it out. Is this as much of a race now in inn snin. Bernie sanders in indiana, Bernie Sanders is demographically favored. The state looks good for him in that way. Polling shows him trailing somewhat. Shows clinton ahead. But if talking to the campaigns, you get the feeling they dont really trust the polling and think Bernie Sanders could win in indiana, and the challenge there, though, is he could wake up wednesday morning and be further behind in the chase for pledge delegates than he was when he started. What i mean is that he at this point needs to win every remaining contest by about 25 points. Thats a lot. If he wants to catch up to Hillary Clinton and pledge delegates. Thats why he held a press conference yesterday and started pitching the idea publicly of flipping superdelegates. He proposed having superdelegates support the will of the voters in their state. If that were to happen, we did the calculations, and sanders would still be behind by about 500 delegates, combining superdelegates and pledge delegates. And the argument doesnt work very well. Its not very consistent with the Bernie Sanders message which is im one of you, the people, the people are standing up. Now the people are voting for Hillary Clinton. Hes losing the popular vote, only about 41 compared to her 556 , the pledge delegate count is behind, so to argue im going to win by getting the insiders and establishment to pet me over the top rings hollow for the guy workg to break up the establishment. Sreenivasan weve seen Hillary Clinton pivot toward a general election posture. Exactly, shes campaigning the appalachia today, tomorrow, a driving tour of these states. What shes doing is a combination. Shes definitely campaigning for these states in these states but shes using messaging and talking about issues she thinks will carry her into the general election. The other thing, she is also fighting with donald trump, and there was the woman card comment that donald trump made hes immediate it repeatedly but also made it primary night last tuesday, her Campaign Announced they raised 2. 4 million in three days on the woman card, 42 of those new donors. Sreenivasan so she has two flanks shes battling on. Yes, although i would argue shes focusing on the general campaign and she said to Bernie Sanders i hired Campaign Managers in the big swing states. Yes im campaigning for the primary still but the general election really has started. Sreenivasan amy walter, tamera keith, thank you so much. Yes, maam r youre welcome. Youre welcome. Sreenivasan five years ago u. S. Special Operations Forces launched one of the most daring raids in history. They invaded a u. S. Ally to kill the most wanted man on the planet. I recorded this conversation last week with a reporter who visited the scene shortly after the battle. With Nick Schifrin who visited the scene shortly after the battle. Nick schifrin was the First Western reporter todrive in abbottabad pakistan and delivered exclusive video, images inside the compound hours after bin laden was killed. At the time nick was abc news correspondent in the region and now a newshour special correspondent and joins me in the studio. What did he r we see in that did video . Saw how the worlds most wanted man lived and died. In terms of how he lived, we see a bedroom, a large bed bigger than anywhere else in the house. We saw the medications he was on simple medications available at the local pharmacy. We saw a pantry where there was a weeks worth of food stored up. We saw so many signs of children. There was a red wagon outside in the backyard, there were 12 kids living there, half were bin ladens. We also saw a satellite dish outside, a oneway communication device. He used to watch tv on the dish but never used it to communicate with the outside world. We s how he died, the pools of blood in his room, the room of his son and the mess navy seals left when they ransacked the rooms for the computers with what intelligence commercials confirmed were th the abbottabad files. Sreenivasan explain the shift from al quaida. Al quaidas kind of become microsoft. Its still got a decent share of the market but its not preeminent, its not seen as cutting edge and doesnt really appeal to the Younger Generation and that is becae of what we call core al quaida, the al quaida leadership as was defined in 9 11 and the years after has been decimated, and that started before bin laden was killed, about two or three years before, probably 2009, the c. I. A. Moved a lot of assets and technology into the region and drones started picking off the leaders. Sreenivasan what about the al quaida affiliates that spread in other parts of the world and are active, franchise operations . Exactly. There was a reason they were killed before bin laden was killed because core al quaida was on the run so you had to have these affiliates and they still have some scuks and thats still the threat of al quaida today. The most prominent al quaida Arabian Peninsula based in yemen, the group thats come closed to attacking the west. The understoodwear bomber, the print cartridge bomb that didnt go off, a member of the team that attacked Charlie Hebdo in paris probably got training from al quaida. But one of the core tenants is ingratiating the population, something i. S. I. S. Doesnt do. Theyre gaining ground in yemen. Right now they actually doing quite well in yemen. Three more affiliates, the most prominent alnusra in syria, again also working with the local population, working with other groups that fight assad, no longer only focused on the west. A. K. I. M. In west africa is grabbing head lines and alshabaab, totally focused on the Somali Government and kenyons who have come into somali. Al quaida still fields the team, still on the field, but not a lot of long passes or touchdowns, trying to gain two or three yards at the time and while the koch isnt liked well by the players, cant communicate well, the bench is still weak but a threat. Sreenivasan thanks. The raid by blandens compound was watched closely by president obama. Among them leon panetta watched the raid unfold in real time from the agencys langley headquarters and joins me now. Secretary, what was that day like for you . It was a culmination of a lot of work that went into it for years. It was. It was an awful lot of work that stretched back ten years almost to 9 11, and an awful lot of people deserve tremendous credit for that the c. I. A. , the intelligence agencies, those involved with the special forces operation. There were just an awful lot of people who did various pieces of the intelligence effort and the military effort that resulted in the raid itself, but it was something that, as an individual responsible for kind of overseeing the operation from the
