The field for possible Republican presidential candidates in 2012, still wide open. And though there are many names on the short list, there is one that you're sure to recognize -- Donald Trump. He's a real estate mogul, reality TV superstar. He's also proving to be quite popular politically. In fact, an NBC/Wall Street Journal poll puts Trump high on the list of potential GOP candidates and the current favorite among Tea Party supporters. Still, there is a lot of controversy circling around a potential bid from "The Donald." Donald Trump joins us live on the phone to set the record straight. Mr. Trump, thank you so much for being here, CNN Newsroom. First and foremost, got to ask you, are you running for president? Well, first of all, thank you for that nice introduction. That was lovely. But I have looked very hard, and I am continuing to look, and I'll be announcing some time prior to June. I hate what's happening to our country. Our country is literally just not respected. It's becoming, in some circles, a laughing stock throughout the world. And I just -- as a person that truly loves the United States, and is proud of the United States, I hate to see what's happening. And you know what's happening right now, we're all paying very close attention, is the potential that the federal government will shut down because Republicans and Democrats can't seem to get on board with the budget. Under a Trump presidency, would you let that happen? Well, it's all about leadership. I mean, don't forget, Barack Obama made one deal in his life, and that was with Mr. Rezko in Chicago, OK, for some land to expand his house. He didn't make deals. It's all about leadership. You have to be able to make deals. You have to know how to make deals. You have to get people in a room and get them done, get the deal done. And this is nothing compared to what's going to be happening next year, because now we're talking about billions of dollars. Next year you're going to be talking about trillions of dollars. Well, President Obama has said that he's summoned them to the White House, he's going to get them in the same room. What more should he be doing? What would you do if you were in his place? Well, it's all up to the messenger. I mean, you could have two people grabbing people and putting them in two separate rooms. They could be the same people, and one messenger gets the job done and one messenger can't. So, it's really very simple. I mean, you have people -- they have to know how to get things done. How would you handle this? And under Obamacare -- which is a total disaster, by the way -- it's going to prove to be an economic disaster if it's not overturned, which hopefully it will be. But you have to be able to get the deals done. You have to get the Republicans -- How would you get this deal done, Mr. Trump? How would you get this deal done? You have to deal with the various people between Mr. Boehner and Mr. Reid, Senator Reid, all of the people. You deal with them and you get something done that everybody's happy with. Would you suggest they take out the social issues, the EPA, the issue of abortion, Head Start? Would you say, you know what, this is not an ideological battle, we've got to pull this from the budget debate and let's just deal with the hard numbers? Well, whether you pull it or not, it's part of the process, and that's part of getting it all done. And obviously Planned Parenthood is coming up, and a lot of other things are coming up, and it's part of the process. It's part of the so-called deal-making process. And if you can't lead them to a proper conclusion, then I guess you're not supposed to be doing what you're doing. You know, you mentioned the Republicans and the long-term plan. We're talking about $6 trillion worth of cuts in the next 10 years. That's the blueprint that they have laid out for the next budget battle. Do you agree that Medicare should be changed fundamentally, as the Republicans have suggested, to more of a system where the elderly would be offered vouchers for private insurance? I'd have to study the plan. I will tell you, I think it's very dangerous for the Republicans to go on this ledge, because I, for one, would have to be very, very careful. I will cherish our seniors. Our seniors are great. And I will cherish our seniors, and I wouldn't do anything to hurt the seniors. Now, what is happening -- and I have a lot of respect for Paul Ryan, but what is happening is the Republicans are going way, way, way far out on the ledge. And the Democrats are saying, oh, gee, look what they're doing. This -- whatever plans and whatever changes are going to be made, it has to be done in a bipartisan way. I don't think the Republicans should be out on this ledge. It should be led -- something has to be done, and it should be led by the president. What would you do? So I think what Paul has done is very dangerous for the Republican Party and very, very dangerous for the upcoming election. I think he's too far out. Again, I have great respect for Paul Ryan. Tremendous respect. But I think he's really going very, very far out in terms of -- he shouldn't be leading this process. Well, whether you pull it or not, it's part of the process, and that's part of getting it all done. And obviously Planned Parenthood is coming up, and a lot of other things are coming up, and it's part of the process. It's part of the so-called deal-making process. And if you can't lead them to a proper conclusion, then I guess you're not supposed to be doing what you're doing. You know, you mentioned the Republicans and the long-term plan. We're talking about $6 trillion worth of cuts in the next 10 years. That's the blueprint that they have laid out for the next budget battle. Do you agree that Medicare should be changed fundamentally, as the Republicans have suggested, to more of a system where the elderly would be offered vouchers for private insurance? I'd have to study the plan. I will tell you, I think it's very dangerous for the Republicans to go on this ledge, because I, for one, would have to be very, very careful. I will cherish our seniors. Our seniors are great. And I will cherish our seniors, and I wouldn't do anything to hurt the seniors. Now, what is happening -- and I have a lot of respect for Paul Ryan, but what is happening is the Republicans are going way, way, way far out on the ledge. And the Democrats are saying, oh, gee, look what they're doing. This -- whatever plans and whatever changes are going to be made, it has to be done in a bipartisan way. I don't think the Republicans should be out on this ledge. It should be led -- something has to be done, and it should be led by the president. What would you do? So I think what Paul has done is very dangerous for the Republican Party and very, very dangerous for the upcoming election. I think he's too far out. Again, I have great respect for Paul Ryan. Tremendous respect. But I think he's really going very, very far out in terms of -- he shouldn't be leading this process. I think this process should be led by the president of the United States. But they're sitting back and all they're doing is criticizing, and that's very dangerous for the Republicans and for the upcoming elections. All right. Mr. Trump, thank you very much. We're going to hear more from Donald Trump in just a moment after this quick break. We're back with Mr. Donald Trump. And Mr. Trump, if you would, you said you thought that Paul Ryan was really in a dangerous area looking at Medicare, actually reforming Medicare. Is there another option? What would you do in a Trump presidency when it comes to Medicare? Because it's going to be bankrupt in 10 years. How would you solve that? Well, I'm studying that situation very, very closely. And if and when I decide to run -- and I really look forward to making that decision, to be totally honest with you. But if and when I decide to run, I'll have a plan. But again, Paul is really -- he's very, very far out in front. The president should be the one that's out in front, and he's being severely criticized. And I will say this from the other side. I will say this -- the seniors have to be cherished, they have to be taken care of. And anything it's going to do that's even slightly negative to the seniors I'm against. Sure. Let's turn the corner here. Obviously, if there was a Trump presidency, you would be commander-in-chief of the troops. We know the Bush doctrine, preemptive strikes against possible terrorists and terrorist threats. The Obama doctrine seems to be a bit more nuanced here, but at least in terms of Libya, is about U.S. interests on a case-by-case basis. If you were president, what is the Trump doctrine when it comes to using the military? Well, first of all, I don't think Obama has a doctrine. And if you look at the way -- Libya has been just totally messed up. You know, at first it was humanitarian, except he was two-and-a-half weeks late, and so many thousands of people were killed. My doctrine is very simple. I want to rebuild the United States. I want this to be a great country again. When would you put U.S. troops on the ground? I want to rebuild -- excuse me. I want to rebuild the United States. And in rebuilding the United States, you know, Libya is -- whether it's Gadhafi, or the rebels -- they make the rebels sound like they're from "Gone With the Wind," very glamorous. I hear they're controlled by Iran. I hear they're controlled by al Qaeda. And I would say this -- unless we take the oil from Libya, I have no interest in Libya. So, your doctrine, would you not have any kind of humanitarian concerns if there is threats of thousands being slaughtered? Would the Trump doctrine unless it deals with oil we're not in? We don't know who's being slaughtered. I mean, who are being slaughtered? The people who shot at us when we were in Iraq? Because I hear 20 percent of the rebels were shooting at us when we were in Iraq. They were opposed to us. I hear a large percentage of them are very, very sympathetic to Iran. And I'm saying what are we doing? We cannot be the policemen for the world. We just can't do that anymore. And Libya is only good as far I'm concerned for one thing -- this country takes the oil. If we're not taking the oil, no interest. Would that apply, do you suppose, to many countries? If you don't have oil, they're not oil interests, that the United States under the Trump doctrine wouldn't get involved in say Ivory Coast where there's a civil war that's ensuing? It's very interesting. In the old days when you had a war -- the old days -- you had a war and if you won the war, you won the war. You won. If there had oil, if they had diamonds, if they gold, when you win a war, you win a war. If you look at Iraq, what's going to happen in Iraq is absolutely amazing. We deneutered the country. We've destroyed their military essentially, we've built it up to a tiny fraction of what it was. For years and years and years and centuries, they've been fighting with Iran, back and forth, back and forth. What's going to happen now is two minutes after we leave, Iran is going to take over the great old fields of Iraq, second largest, by the way, to Saudi Arabia. $15 trillion. And we've spent $1.5 trillion in Iraq. We've lost thousands of lives and wounded. And I'm saying if Iran is going to take over those oil fields, we're going to take them over. And I will tell you this. If I'm president at the time, Iran is not taking over the Iraqi oil fields. We will. Now, what's going to happen is if we leave, they're going to take over. So, I would say we take over the fields, and we have no choice. Otherwise, all of those great men and women will have died in vain. All right. I want to turn the corner, if we can. I know there's been a lot of controversy over some statements that you've made again questioning President Obama, whether or not he was born here in the United States, American citizen. You're saying you're sending a team of researchers to Hawaii to take a look at whether or not that is the case. Mr. Trump, I mean, this has been debunked by so many people on so many levels, including CNN. We did our own documentary, been to Hawaii numerous times, speaking with people not only who knew his parents but the childhood schoolteacher, the baby-sitter -- That has nothing to do with whether or not he was born in the country. [Crosstalk] You say yourself, Mr. Obama, that there's nobody who remembered him you said as a young child in Howaii. We've spoken to those people who do remember him. I want you to listen, just take a listen here to what they say, what they recall. [Begin Video Clip] He was very funny. He was really warm, friendly, kind of a prankster. Smiled. Big smile. Lefty. Nice little left-handed jump shot from the corner. And nothing but net very often. [End Video Clip] So, Mr. Trump, I mean in listening to -- Excuse me -- -- to people who were there in Hawaii who recall him as a boy. You say there's no one who recalled him from kindergarten or from his young childhood on "The View." There are people who are there who recall him being born there. The governor says that he recalls him being born there - - I didn't say that. I'm sure the governor really recalls him. I think the governor's taking a bullet for the party. Look, I didn't say that. You have to be born in the country. If he was three years old or two years old or one year old and people remember him, that's irrelevant. You have to be born in the country. There's no birth certificate. There's only a certificate of live birth, which is a totally different thing and a much, much lower standard. There are no hospital records. His own family doesn't know what hospital he was born in in Hawaii. But have you no hospital records in any of the hospitals that he was born there. There are no bills, no room numbers, no nothing. They do that for other people, but they don't have for Obama. His grandmother in Kenya said that he was born in Kenya. Now, he could have been born -- and she said it very strongly -- that he was born in Kenya, she was there when he was born. And the newspapers were a week late. So, he could have been born in Kenya and gone over to the United States. Everybody wants to be a U.S. citizen, and his grandparents put an ad in saying he was born in the United States because of all the benefits you get from being born in the United States. Mr. Trump, I have -- So, I think CNN has not done a very good job. No, I have to interrupt here because I know what you're talking about. I know the report you're talking about. Within that interview itself -- it has been discredited. There is an interview that was done here, and in the interview, Obama's step grandmother says that she was there when he was born. The interpreter realizes when the questioner again asks him if he was born in Kenya that she was misinterpreted, that that was not correct. Oh, I see. Now it is a misinterpretation. It is sort of amazing. Well, if you listen to the interview and you see the transcript here, it says, no, Obama was not born in Mombasa, he was born in America. The interviewer, the translator, asks again if this is the whereabouts of where he was born, he thought he was born in Kenya. And he says, no, he was born in America, not in Mombasa. OK. Well, you know you have a big dispute on that. Absolutely. But the Kenyan grandmother, that report was disputed within the interview itself. And you're a man of great credibility. I would assume that you would want to make sure that in fact was the case. Well, you know, you have people that dispute what you're saying, and I say it with great respect. By the way, I hope he was born in the United States. I'd like him to be. Because if I decide to run, I would like to really do it on a very, very straight-up, head-to-head, man-to-man basis. I mean, honestly I hope he was born -- because if he wasn't it is the greatest scam in history. Not political history, in history. But have you a lot of documentation and you have a lot of documentation -- by the way, not only here but stuff that's missing. Why are there no hospital records? Why does his family not even know the hospital he was born in? And just out of curiosity, why can't he produce a birth certificate? I hope he can. Well, I know -- clearly, Mr. Trump, I know you've seen the certificate of live birth -- It is not -- -- that was presented by the White House. Governor -- Governor Abercrombie says that this is the official document -- Oh, really? It's not signed by anybody. Nobody wants to sign it. Why doesn't somebody -- nobody signed it. Since when do you -- I have a birth certificate signed by three different people. Why is it that it isn't signed? A certificate of live birth -- you can't get a driver's license with a certificate of live birth. You can't get a wedding license. It is totally different from a birth certificate. I think you're -- Let me ask you this. Do you really believe that the governor of the state of Hawaii was there when he was born? Give me a break. I've spoken to the governor of Hawaii, Abercrombie, when I did the documentary on the president. He's very close friends with the mother -- Oh, really? -- as well as the father -- I wouldn't be surprised if he hardly knew them. They have a very, very close relationship. Oh, I see. He was there in the hospital when he was born. You'll have to speak to him yourself. But I mean, I have spoken with the governor, Governor Abercrombie. I know this debate continues, but I mean, clearly, there is information and there's evidence on this side that point to the fact that the president was born in Hawaii. But I know that this is not an issue that's really important to American voters. Our latest poll showing that 70 percent want to move on and talk about some other things. Well, what about the 30 percent? Do they not count? Of course they count, but I'm certainly glad that -- That's a lot of people. -- that we had an opportunity to talk about some other issues. Clearly your own doctrine, domestic policy as well as international. So, Donald Trump, thank you very much -- Well, that is my main issue. I'd just like to see the United States be great again and not be ripped off by every country throughout world, which is happening right now. That is 99 percent of what I'm all about. OK. Well, we certainly hope to focus on that if you decide that you're going to jump into the race. So, we appreciate your time. Well thank you very much, Suzanne.
