This mornings eye opener is presented by toyota, lets go places. Welcome to cbs this morning. The nations fourth largest city is struggling with deadly widespread flooding triggered by historical rainfall. More water rescues are under way in houston this morning, even as flood waters recede. Five people died yesterday in southeast texas. Nearly a foot and a half of rain reportedly fell just west of houston. More wet weather is in the forecast. Texas and nearby states face possible flash flooding through thursday. Omar villafranca is in houston where people are rushing to escape water. Reporter good morning. Some scary moments in northwest houston when rescue crews had to use boats to get residents out of an apartment complex. You can see some of the residents are here. They were able to grab basically just a few thing, some clothes they could wear today, rescue a few pets. This is also runoff from yesterdays record rainfall. The amount of rain, historic. The rescue attempts, dramatic. Streets became waterways, littered with People Holding only what they could carry in their arms, and entire neighborhoods swallowed by rising waters. We panicked. We have a 2weekold. The water keeps rising. It was unsafe for him. Its terrifying, especially if you cant swim. Reporter First Responders worked around the clock, in boats and even jet skis, saving children and seniors and pets. Bruing him through. Reporter rescuers dove into neckhigh water to save livestock from drowning. People escaped to safety any way they could. On air mattresses, in empty container bins, even inside refrigerators. Texas governor greg abbott. Please remember the easy phrase turn around, dont drown. Stay out of the rising water. Ever seen anything like this before . Last time it got like this in this area was allison. The water line came up to here. You had about a foot of water. About a foot, yeah. Reporter this is the largest flood event to hit the houston area since Tropical Storm allison in 2001, where 23 were killed in texas alone. Engineer sanita singh drowned while flood waters overtook her car. Her husband says his heart is broken. Cancer, a heart problem, i understand. But this . Theres nothing that could be done. Its a terrible loss for me, for everybody. Reporter many schools in the houston area are closed today as cleanup gets under way, but there is more rain in the forecast. Gayle . Thats the last thing they need. Thank you very much, omar. We have breaking news from afghanistan, where dozens of people were killed in a Taliban Attack on a Government Security agency. It began with a suicide car bombing this morning outside the agencys compound in kabul. Gunmen then stormed in and started shooting. Security forces fought them off, leaving at least 28 dead and more than 300 others wounded. President obama today begins a weeklong trip to saudi arabia, britain, and germany. At his first stop, hell talk with saudi leaders facing trouble at home and abroad. Hell also meet with leaders of six persian gulf countries to discuss the fight against isis. The president talked with us about his Foreign Policy monday at the white house. We sat down after officials announced another 200 american troops will be sent to iraq. They will help local forces troo i to recapture a key city from isis. This is a long, hard fight, as i just said last week, but what weve seen is theyve lost territory. As we see, the iraqis willing to fight and gaining ground, lets make sure were providing them more support. Were not doing the fighting ourselves. But when we bprovide training, when were gaining intelligence working with the coalitions we have, what weve seen is that we can continually tighten the noose. My expectation is that by the end of the year, we will have created the conditions whereby mosul will eventually fall. When you arrived in office, i think one of the early things you said to the cia director is, i want to get osama bin laden, and you did. I assume you feel the same way about baghdadi. I feel the same way about the entire isil leadership structure, which is as wicked and as destructive as any group of individuals on this planet. And do you think youll be able to get baghdadi by the end of your term . My goal is to make sure that were doing things right and weve got a plan and we execute. You take bin laden as an example. I would have liked to have gotten him the first year, but you dont have that luxury as president. What you have the ability to do is to put and train all the pieces, intelligence, military, diplomatic, and you just keep on grinding it out. Let me turn to something thats been in the news recently, which is the 28 pages of the 9 11 report. Have you read it . You know, i have a sense of whats in there, but this has been a process which we generally deal with through the Intelligence Community and jim clapper, our director of national intelligence, has been going through to make sure that whatever it is that is released is not going to compromise some Major National security interest in the United States. There are just reams of intelligence coming through constantly. Some of them are raw and not tested. Some of them are and some of that may be in the 28 pages. Some of that may be in the 28 pages and i dont know. The point is, its important for there to be an orderly process where we evaluate this because what can end up happening is if you just dump a whole bunch of stuff out there that nobody knows exactly how credible it is, was it verified or not, they could end up creating problems. But the point is, its been a long time. Yeah, it is. A long time. That i can acknowledge. Hopefully this process will come to a head fairly soon. And what about this legislation in the congress that will allow families to sue the saudi government . And other governments in similar circumstances. This is not just a bilateral u. S. Saudi issue. This is a matter of how generally the United States approaches our interactions with other countries. If we open up the possibility that individuals in the United States can routinely start suing other governments, then we are also opening up the United States to being continually sued by individuals in other countries. Really interesting as the president is embarking on a trip to saudi arabia today. Yes, and the interesting thing, talking about the 28 pages, you get a sense, theres so much talk about it, that something is going to happen soon in terms of releasing that. Theres a lot of stuff in there that may not be incriminating, as some suspect, but a lot of stuff because they did a lot of investigations at that time. It has been a long time. Why now . Couldnt they have done this earlier . In our next hour, the president talks about russian president putin. You can watch the entire conversation tonight on my pbs program. The polls are open right now in new yorks crucial president ial primary. Hillary clinton and donald trump want top wi widen the gap betwe them and their opponents. Trump is expected to win most of the 95 republican delegates. We begin with major in the republican race. Hes at a Central Synagogue in midtown manhattan. Major, good morning. Reporter good morning. Light turnout so far, where donald trump is expected to arrive and cast a ballot for himself in the next couple hours. Big question as you indicated, how many of new yorks 95 delegates will trump win tonight . His top strategists believe hell win most. By that, they mean a range of anywhere from 88 to 92. That will propel trump toward five primaries next week and keep alive his hopes to claim the republican nomination outright. Were going to start winning, winning, winning. Reporter its been almost a month since donald trump won a primary, but with a new york victory in sight, hes starting to talk like a presumptive nominee. Were going to do it on the first ballot. Were going to get to that big 1237. Reporter trump expects to do well in five states voting next week, and hes well positioned to win a solid share of the 172 delegates awarded or influenced by the primary outcomes. No new yorker can vote for ted cruz, and no new yorker can vote for kasich. Reporter despite trumps bravado, kasich said trumps complaints about gop rules prove he has doubts. Were going to go to an open convention. Theyre beginning to realize that. They dont like the idea of an open convention. Reporter and trump tried even harder than ever to celebrate 9 11 heroism, but the effort fell short. I was down there, and i watched our police and our firemen down on 7 11, down at the World Trade Center right after it came down. Reporter trump also suggested he had a personal hand in cleaning up after the attacks. Everyone who helped clear the rubble, and i was there and i watched and i helped a little bit, but i want to tell you, those people were amazing. Reporter we asked Trumps Campaign what he meant by saying he helped out a little bit at ground zero, but gayle, we never heard back. All right. Theres still time. Thank you very much, major. Hillary clinton is down playing talk of a big victory but appeared confident yesterday. The New York Post headline says the former senator is feeling the bern, shows her sweating a little bit, as her brooklyn born challenger tries to pull off another upset win. Nancy is at clintons polling place in new york. Nancy, good morning. Reporter good morning. Behind me is the Elementary School where clinton herself cast her own ballot the two times she ran for senate. Shes feeling so good about her homefield advantage that in a slip of the tongue late yesterday, she said that shes hoping that she can wrap up the nomination today. Now, mathematically, that is not quite possible, though a win in this delegaterich state certainly would help. She quickly amended herself to say shes not taking anything for granted. And she cant because Bernie Sanders is the one who has been drawing massive crowds here in new york. 15,000 here, 25,000 there, and he has shown he can close the gap before. He was ten points back in michigan, for example, just as he is here, and he ended up with a narrow win. The big difference here in new york is that clinton has virtually the entire new york power structure on her side. Shes been campaigning with both new york senators, with new york citys mayor, with the new york governor, and sanders admitted to me yesterday, that this is going to be a tough race for him. He said dont count him out, but its going to be tough. And the bigger challenge looming for him is that there are five more northeastern states that are voting next week. According to almost all of the polling thats been done, hes trailing in most of them. All right. Nancy, thank you so much. Managing editor of Bloomberg Politics is here. Good morning. You just heard nancy report that, the senator saying yesterday she hopes to wrap up this no, mamination today. Could it be closer than expected . It could be closer than expected. Bernie sanders has, in most of these states where hes spent a lot of time on the ground and an the air with advertising, has tended to close the gap. If you look at the public polling and the private polling, it seems like shes going to win handily, whether thats in the high single digits, maybe low double digits. You never know what can happen on primary day. Suppose she wins. How quickly can she wrap it up, as they say . Well, the question is the definition of wrap it up. She wins a big victory here if she wins on a scale we think shes going to win, shell add a few extra delegates. If he were to win by a narrow margin, big, huge upset, he wouldnt gain much in terms of delegates. Shes still ahead 200 pledge delegates roughly speaking. But hes got the money and inclination to keep going. Shes going to have to fight through every primary and caucus through june 7th. She wont wrap this up probably until the convention because shes going to need super delegates probably, almost certainly, to be the nominee. But every contest where sanders does not close the gap by an appreciable amount is another contest in which he, in fact, is falling behind in terms of what he actually has to do. The math gets harder and harder for him every time he either doesnt win a state 60 40 or he loses, as he might today. Lets look at the republicans. If all goes according to plan, donald trump is going to win huge here in new york, according to him. I like how you say that. Now you cant say the word any other way. Every time i hear it in my head, i hear Bernie Sanders voice. How is he doing when it comes to the delegates . He doesnt seem to be holding up as well as ted cruz when it comes to garnering the delegates. Ted cruz is playing the inside game really well. Donald trump seems to have found his footing again in his home state. Hes likely to win all of most of the delegates here. As your segments earlier suggested, hes got a good calendar down the line. If he continues to win big, theres a chance he could end up getting the 1237 delegates and actually get this nomination before the cleveland convention. That is his goal. John, thank you so much. Trump is complaining about it being rigged because he knows its going to be an open convention. You buy that . Could be. Okay. Thank you, john. Rescuers from around the world are traveling to ecuador to help search for victims of the countrys devastating earthquake. The death toll of at least 413 people is expected to rise. One american is among the dead. More than 2600 people are hurt, and up to 100,000 may need aid. Reporter norah, good morning. So many people are sleeping outside this morning. Families, mothers and fathers, kids. They have nowhere else to go. Their homes have been destroyed. This morning as they sleep outside, now that we see the sun, search and rescue is resuming, and theyre still finding people alive, buried under rubble. From beneath the rubble, a sign of life. This hand belongs to a man trapped under a flattened shopping center. Firefighters pulled him out alive along with two other women on monday. They were wedged between a floor and a roof for more than 32 hours following the devastating 7. 8magnitude earthquake. I felt that she was alive, said the husband of one of the survivors. Rescuers frantically worked to free a man trapped under a collapsed hotel. As news of another survivor spread, dozens of people rushed to the scene. We spotted this woman. She looked helpless. It was her husband who was stuck. He had called her on his cell phone from underneath the rubble. Hes alive but trapped, she told us. Soon she was too overwhelmed with emotion to even speak. Moments later, firefighters p l pulled pob low out. A total of eight bodies were removed from the hotel. Pablo was the only one found alive. Despair and frustration are setting in. People have waited in long lines for food. Some people here havent eaten in days. The widespread destruction has left thousands of people in need of shelter and without power. Ecuadors president says rebuilding could take years and cost this country billions of dollars. There have been more than 250 aftershocks, and they keep coming. Gayle, every time people start running, its because someone has said, hey, i see someone under the rubble, i hear them, lets go. All the rescuers head to that location. As one rescuer said, right now were focused on finding people, were focused on those who are alive. We can come back to the bodies later. Boy, all right. Thank you, david. Reporting from ecuador.
