President ial visit to the island in 88 years. The last time was 1928 when calvin koolidge went to havana. Part of the mission during the 2day trip this time constructing a frank dialogue about human rights issues, and other differences that sparked a 50yearold cold war between the two nations. The visit is not without detractors, here and in cuba. Republican leaders continue to bash the president for what they call supporting an oppressive regime. Support correspondent joins us. How is the president addressing the objections that some have to the visit . One of the ordinarily goals is to cement and solidify the president s initiative. You recall it was on september 2014 where he made a surprise announcement that he was going to pursue the normalization after 53 years of estrangement between the United States and cuba, followed by the mutual openings of embassies, and the fanfare around that. Removing some of the context around that and the american companies. Part of a goal to expose cubans to american society, open communication with america itself. What the president is trying to do here first and foremost. And you see it with the stage craft and choreography. The president landing aboard aircraft one, touching down with his wife in to you. Spring breakers. Malia and sasha, and his motherinlaw. One of the first things hes done, a tour, public tour looking at the sites around me, we expect the president in the square, in a couple of minutes. Perhaps unfortunately, a discord nant note. It poured rain the moment air force one touched down. Part of the reason is the president is trying to cement this in case a republican is elected to succeed him in the white house in the midst of the election year. Who knows what could happen. The first place bass an address to embassy staff, where he called this an historic opportunity. Everything we have accomplished so far. Americans coming to cuba, engagement with the cuban people. Still societies, faith groups. Entrepreneurs, young people, more opportunities to improve their lives, its happening because of you. The president continues his tour of old havana. He has a full slate of activities. This is a state visit. A lot of pomp and ceremonies. Nothing has changed using the old policies of the u. S. He wanted to do something. He has not been able to change something that would be fundamental to relationships to any nation, and that is the trade embargo. Where do they stand between the u. S. And cuba. The president. In this is almost a commercial trip. He has ceos of major organizations, head of zero, paypal, b b and others. They sense an opportunity, the administration is doing all that it can to loosen things up. Incrementally theres mail between the United States and cuba. Cubans can be paid through u. S. Banks. That will benefit Baseball Players and a number of other cubans that go to the United States. The trade embargo has to be raised by congress. Lifted by congress. Its been in place since the castio regime came into power. Coddified in 1996. Republicans show no inclination to do that. You pointed out at the top they have been critical of the president visiting the craft roe regime. Still, the president. Ignoring that, pushing it aside, as said many times, the past policies of the United States isolated cuba. It has not worked. Hes turn the page in a high profile way today and the next two days. What is on the agenda for tomorrow, mike . Tomorrow begins the official state visit portion. He visits a memorial to the 19th sendury cuban nationalist hero, before he visits the president , raul castro, fidel castro having ceded the presidency toies younger brother.

Brett neumann has more from the leader who has been mending fences. In size and character, raul castro could not be more different from the brother that he replaced as president of communist cuba.

To everyones surprise, he released restrictions on Small Business and travelling abroad. Raul is more liberal. We have to open up. Reporter raul is a prague in theist. Me mag mattist. He is more like we have to solve the matters for the people. He feels the revolution must be saved by helping the people. Reporter he is, in fact, pragmatic enough to put ideology and years of mistrust aside in order to reconcile with the arch enemy. Raul castro is equally committed to maintaining cuba as a oneparty communist state. The same way we have never suggested the United States change its political system, we demand respect for hours. Reporter raul castro is due to step down in two years. With the clock ticking on the castro era, he is determined to follow vietnams example make peace with the United States, open up the economy and maintain the grip on political power coming up at 8 30, president obamas visit to cuba in the week ahead. Well take a look at where u. S. Cuba relations stand and how the president will push his agenda in his final months in office. Now to america votes. Donald trump is downplaying the latest violence at one of his rallies. Video from arizona yesterday appears to show Trumps Campaign manager reaching for the collar, trump and calling him spirited saying he wanted to remove offensive signs from the event.

O. P. Race. Along the way he picked up 164 delegates. Who gets the delegates now. The answer is not as simple as winner take all. Paul beban takes a look at the options. I want to congratulate donald trump on his victory, a big victory. It was the final blow for marco rubio. A disappointing finish in his home state. Now that he has no longer in the running, what happens to the delegates. The answer, because the Republican National committee allows each state to set rules, its complicated. First there are three states where marco rubios supporters can or will be reallocated without them haivng a say. Next is the big group of states where marco rubios delegates would be what is called unbound. Able to vote for whomever they want, sooner or later. In a few states the delegates can choose a candidate. In others they are stuck with marco rubio until he releases them. Finally theres the states when the delegates are bound, marco rubios, until the convention. That is when things could get more complicated. Some states require the delegates to vote for marco rubio on the first ballot. Others to vote for him the entire time. Thank you and god bless you. Reporter but that and other rules could change between now and when the republicans arrive in cleveland for the convention in july, as we have seen in this campaign, the cold rules do not the old rules dont apply pull out the calendars, here is what is next.
