A step that means athletes no u. S. To legally work there. While the cuban public is enthusiastic about the president s outreach, the castro government has been slow to make many of the changes that the administration asked for. Relations with the United States have to overcome the great obstacles of history. And there is still a suspicion that, this normalization process is a trojan horse. Designed to kill the cuban revolution with love rather than with aggression. In many ways that is the strategy. The Obama Administration hopes that increased financial opportunity will bring irreversible change to this authoritarian state. Michelle, tomorrow, president obama will meet cuban leader raul castro to press for more reform. All right, margaret. Thank you.

Trade policy a hot button issue on the campaign trail with candidates on both sides trashing deals that they say cost america jobs. Secretary cost us 800,000 jobs nationwide. But i will say trade deals are absolutely killing our country. The question is are International Trade deals helping or hurting the American Worker . Here is cbs News Business analyst jill schlessinger, which is it . Little of both. The north American Free trade agreement, 1984, the one Bernie Sanders said cost 800,000 jobs, probably didnt. It was probably a wash. According to economists. And chinasen troo into the World Trade Organization was a game changer. Look at exporting and manufacturing in the u. S. Since then, down 9 . Chinese exports and manufacturing up by 12 . Remember overall. U. S. Consumers buy goods a lot cheaper since all the trade deals. Trade shuffles the deck. Who are the winners and losers here . I think that manufacturing has been a loser. We should note manufacturing jobs actually peaked in 1979. So thats 15 years before nafta. Whats really changed the game . Technology. Automation. Sectors around technology, we saw technology up 30 since 2003. And we should also note one big winner, the world, because we have seen millions of people lifted out of poverty. What about the folks back home . How do you help those people who lost their jobs . Not ripping up trade agreements. Trade wars are terrible for economies. But by really spending money on retraining and offering Financial Assistance in the form of tax credits. Thats probably the best solution. Cbs News Business analyst, jill schlessinger.

Coming up, while many were sleeping the unblinking eaglecam made the catch of the announcer this is the cbs overnight news. Welcome to the overnight news. Im michelle miller. The next stop on the president ial campaign trail comes tomorrow. The democrats will hold a caucus in idaho, utah and arizona will be holding primary elections. Arizona is a winner take all state. And it saw its share of antidonald trump protests over the weekend. Trumps gop opponents, ted cruz and john kasich are hoping to capitalize on the unrest within the Republican Party. John dickerson spoke to kasich for face the nation. Governor, to get the nomination you would have to win delegates. How are you going to do it . First of all, nobody is going to have the delegates they need going to the convention. Everyone will fall short. The convention by the way is an extension of the political process. So, what will happen is people will go there with a certain number of delegates. Well go into cleveland with momentum. Then the delegates are going to consider two things. Number one, who can win in the fall . I am the only one that can. Thats what the polls indicate. Number two, john, a crazy consideration like who could be president of the United States . And i think when they take a look at my record, both in washington and in ohio, with the job growth, the wage growth, you know, reforming the pentagon, and then, they can understand that i have the crossover appeal. I think i will be picked. I dont think anybody is going to get there with the delegates that they need to win. Why should the person who goes into the convention, dont why shouldnt they get the nomination . You know what . Its like one of my daughters said like i had an 86. My other friend had less than that. I should get an a. Weve got rules. You know, sweetie, you got to make a 90 to get an a. We have rules as to how many delegates you should get. If you go in way ahead you are likely to be picked. Whats interesting in the ten contested republican conventions, you know that the leader going in only got picked three times. And again, john, i have to tell you that, who is going to win in the fall . Who is going to beat hillary . These folks cant win. They cant win ohio, i can tell you that. In addition, look at the resume. Look at the record. Who actually can fix this country . Who can get us moving again . Both the domestically and with foreign policy. So that should be a consideration now, not much of one, to be honest with you, but when we get to a convention, see, because i was there when Ronald Reagan actually can you imagine how many people were mad at reagan . But his message mattered. He came close. He ultimately became one of the greatest president s we have ever had. The convention is a very interesting thing. And delegates take things extremely seriously. Has anyone let me also tell you, john, if somebody can get the numbers, they would win. Has anybody theyre not going to get the numbers. Everybody chill out. Some people suggested you should drop out so somebody can get the numbers. Ted cruz is closer to the number than you are. He needs 80 of the vote to get it. Thats not going to happen, john. You know it. I know it. Has anyone asked you to drop out though . Nobody is calling me directly and asking me to drop out . And by the way why dont they drop out. John, why dont they drop out . Im the one who can win in the fall. You know another interesting thing. This party has run around for seven years saying, how is it that we elected a one term president who never had the experience. Whatever happened to that . Remember that . So, heres what i would say. I can win in the fall. They cannot. You say you are delivering a positive message. You have stayed away from some of the back and forth. Would you not in the pursuit of your nomination not want the help of the stop trump forces . The organized efforts to stop donald trump . You know, john, im not, i am not in this for some Political Science game or some calculation. Let me just tell you, that people are nervous about their work, their wages, their kids future. Thats what i focus on. Responding to that legitimate concern that they have. And i tell them exactly how in washington. We had Great Success and balanced the budget and grew jobs. And i tell them about the 417,000 people who are now working in ohio who didnt have a job when i became governor i have people that come to my fact that i have focused on the issue of Mental Illness and drug addiction. Thinking about this antitrump group or that group. Let me do my job. Communicate to the public. Well see where it ends up. I think this is a very construct constructive message to the American People. I want you, the American People, you in your living rooms to believe you can change the world. We need you to do it. Because the you will revive the spirit of our country. But governor, the people trying to stop donald trump believe that many of the things you just described are imperilled by his candidacy. And that gets them a little exercised in the same way you are exercised. So i just wonder if you think theyre wrong, crazy, missed something . No, let them go and do. You know what is interesting . Some of the same people wanted me to get out of the race. They wanted to get behind rubio. What happened . Rubio is out. Im in. If i dont win ohio, guess what . Trump is the nominee. I win ohio now they want me to get out. What are you, these are the same establishment people that have been fighting me my entire political career. You know what . I will tell you what is in my minds eye. The people i grew up with in the mckeys rocks, people walked door to door for me. We had people from 22 States Manning phone banks in ohio. They came from all over the country to help. Theyre hopeful together we can raise this country. I dont have time to think about all this political calculation in some back room some where. Okay, john. Im any just not doing it. You have known me long enough to know that what you see is what you get. Period. End of story. But you have in fact brought on people to help you with the the calculation, people with experience. Sure. So you are in fact thinking abut the calculation. You dont want to talk about it. John, look. First of all, the convention is an extension of this process. Of course i want stu spencer, of course i want charlie black, of course i want tom ridge, of course i want the former governor of utah. I want them all to help me. What do we think the convention is some sort of subterfuge it . Is nothing more than extension of what we are doing now. If nobody gets the delegates, which they wont, then we will have to work, you know, have to work it to convention. I will spend my time convincing them about my electability and my record. If they buy it, great. If theyve dont. I will have done my best. John, i am perfectly comfortable with this. Let me ask you a president ial question about Merrick Garland put forward by the president for the supreme court. This could be a decision you have to handle. Whats your feeling about the way your republican colleagues have responded to that nomination from the president . Look, i never thought the president should send it. I knew nothing was going to happen. Frankly they probably ought to sit down and meet with the guy. My feeling end of the day who ever gets elected president able to pick, you know, who they want, and, and, the American People will decide by either voting for a republican or democrat what the makeup of the court is. I just think thats a process that can unite us. Rather than a process that right Bernie Sanders is looking for a big comeback in tomorrows nominating contest. Sanders trails Hillary Clinton by a wide margin in the delegate count, but isnt giving up the ship. Sanders spoke with John Dickerson for face the nation. Senator, we looked at the math here for the contest going forward. It looks like you would have to win almost 60 of the remaining delegates. So what is your path to the nm nation . That is a big number . It is, but the states that arizona, we are heading out west. To washington. We have alaska. We have hawaii, and we are heading to new york. We think the father forward is a prtty good path for us. Clearly secretary clinton did very, very well. In the deep south. Not a strong area for us. But i think as we go forward, are you going to see us doing better and better. I think people are going to polls. Bernie sanders does better against donald trump than Hillary Clinton does. In fact in the last poll we were 18 points ahead of donald trump than secretary clinton. I think that will play a factor in the coming states. Secretary clinton won in the illinois and thats not the deep south. Heres the point as you know she did. And we won in michigan. End of the day if you look at michigan, illinois, missouri, we come out almost the same in terms of delegates. Hillary clinton has 2 million more votes than you have. Presidency has been to create a movement, to create momentum, to gather people. She seems to be able to gather more people behind her message than you. Isnt that a threat to the, to the theory of the Sanders Campaign . No, no, no, no. John, not at all. What you are really talking about is she did very well in the deep south. She creamed us in mississippi, alabama, south carolina. Now i wish i didnt have to say this, but everything being equal, no democrat right now, i hope that changes, i think it will is going to win those elections, those states in the general election. We have now won nine states. I think in a couple weeks you are going to see us win more states. I think as we head to the west coast, which is probably the most progressive part of america, the ideas that we are fighting for, dealing with the grotesque level of income of and wealth inequality, a National Health care system through minimum wage, 15 an hour. I think the people in those be voting for a establishment politics and establishment economics they want real change. I think we are going to do well there. One last tactical question, senator. There has been a report that you might go to the convention. If you are behind in delegates try to flip the superdelegates to win through using superdelegates. Is that a strategy you are looking at . The whole concept of super delegates is problematic. I would say in states where we have won you know by 20, 25 points, you know what i think it might be a good idea for superdelegates to listen to the people in their own state. Other day. Who said, you know what. I am going to listen to my state. If my state votes for you, bernie, you will have my vote. I think that i would hope that a lot of the superdelegates take that factor into consideration. So yes that is a strategy you are pursuing . Well, to say to a superdelegate. 20, 30 points, you know you might want to listen to your state. I think superdelegates should do that. If they didnt come from a shouldnt feel compelled to go for you . Well thats, legally they have their own decision. To be made. They have their own right to make the decision. But i would argue that many of the superdelegates for them, what is most important as it is for me and secretary clinton by the way, is making sure that no republican occupies the white house. And if people conclude by the end of this campaign, if we have the energy, and an if, if we win a number of states. Thats also an if. But if that its the factor and it appears that i am the stronger candidate against trump, i think you are going to see some superdelegates saying, you know what i like Hillary Clinton but i want to win this thing. Bernie is our guy. Its been months since south carolinas republican senator for the gop nomination. Since then he has been an unofficial spokesman for the Republican Party establishment, opposing both donald trump and ted cruz. Well, graham was singing a different tune when he sat down to talk with John Dickerson for face the nation. You once said that choosing between trump and cruz is like the difference between being shot or poisoned. So, how is your health . You know, maybe they will find an anecdote for poisoning, hard once you are shot to get over it. The bottom line i believe donald trump would be an utter disaster for the Republican Party, destroy conservatism as we know it, we would get wiped out and trump candidacy. Ronald reagan had a threelegged stool of conservatism. Fiscal, social, Strong National security. Donald has a four legged stool got to be bigger. Economic populism, xenophobia, race baiting, and religious has formed. Thats his campaign. That is not conservatism. Ted cruz in my view is a real republican who i often disagree with. Ive am supporting ted i think he is the best alternative to donald trump. John kasich is the most electable republican. I dont think he has a chance to win. At the convention, because it is an outsider year. John kasich is an insider. Most delegates are looking for an outsider. I love john kasich. If he stays in the race or they dont coordinate the efforts between cruz and kasich, were going to wind up giving the nomination to trump. You say an outsider year. Your description of Trumps Campaign. A very popular campaign. People turning up to the rallies. He is getting the votes. 35 to 40 , where he is going to be. A lot of people believe that illegal immigration is a real problem. Playing on their fears. He says most of them are rapists and drug dealers, theyre not. Heres why we are losing the about your economic plan or ability to defend the nation if you are going to depart their grandmother. Im in the party of family values. I like that. There are 11 million illegal immigrants. 60 here a decade. Many have american children. American citizen, children and grandchildren. What will happen to republican friend if our position if they take their grandmother, member of the military, who is illegal. How do we get the person to vote for us if we will deport their grandmother when all she has done is violate the immigration laws. This is why we are getting killed with the hispanics.

There wasnt anything that would lead me to believe that this was on the radar that he is going to go join isis. Khweis did join isis investigators want to know how and why. U. S. Authorities say in december of last year, khweis left Baltimore Washington International airport for england there, he traveled to amsterdam, met a woman that took him to turkey and crossed into syria. He decided a month later life with isis wasnt for him. And fled. Prayer, eating and learning about the religion for, about eight hours. It is not only foreign fighters looking to get away from the Islamic State. In syria, Holly Williams spoke to a young man who fought for isis to be turned away by the groups dark side. He is treated like a dangerous criminal. And says he was trained to kill by isis. Before being captured by kurdish soldiers. But mohammad is a frightened 18yearold and asked us to hide his face for his mothers sake. She often told me to leave isis, he said. But i never obeyed her. He grew up in a muslim family in syria, but told us he knew very little about islam until he was recruited by an uncle and a village elder. They recited verses from the koran to explain that muslims then they sent me to a camp to learn about islamic law. Gradually i became convinced. Mohammad seems less a committed extremist than simply naive. It doesnt lessen his crimes. But shows the that isis which relies on fighters who kill die for the cause, has a weakness. Mohammad told us he began to lose faith in isis when he witnessed one of the groups many public executions. What did you think when you saw that . Did you still think that was the real islam . No, he said. It was horrific. I wish i had never seen it. He also told us that u. S. Coalition air strikes are taking a heavy toll on isis.
