George is not here. Not george. Not george. His dancing shoes. George is off. David muir is here for us and weve got a lot to talk about about the president ial race. Yeah, weve been talking about it before we even came on this morning. The fiery debate, republican candidates on that stage, marco rubio, ted cruz once again taking aim at donald trump and trump, of course, firing back. Thats right. Absolutely. Take a look at this. Hillary Clintons Campaign having a little fun during the debate. There they are tweeting out an image of three republican candidates arguing and a shot of clinton looking, well, slightly less than impressed. We are going to hear from senator rubio in just a moment but first lets get right to abcs tom llamas in detroit for good morning, tom. Reporter robin, good morning to you. You know, the debate went to a very weird place last night and donald trump forced to confront a pattern of flipflops that was shown in a video at the debate. Overnight, the Republican Debate starting with a low blow. He referred to my hands, if theyre small, something he must be small. I guarantee you theres no problem. I guarantee you. Reporter the wild night even had a moment of zen. That is not what you said. I know its hard not to interrupt but try. Breathe, breathe. Lying ted. When theyre done with the yoga can i answer the question. You cannot. I really hope that we dont see yoga on this stage. Hes very flexible so you never know. Reporter when it was serious, trumps rivals focusing on his record as a businessman. He can start tonight by announcing all the donald trump clothing will no longer be made in china and mexico but here in the united states. Here we go. They devalue their currencies and they make it impossible for clothing makers in this country to do clothing in this country. Reporter trump and comoderator megyn kelly remaining civil after their epic battle in the first debate. Mr. Trump, hi. Hello. How are you doing. Nice to be with you, megyn. Great to have you here. Youre looking well. Youre looking well. As are you. Reporter but later kelly putting Trump University in the spotlight. The business now the subject of lawsuits over claims they defrauded students out of thousands of dollars promising to teach the secrets of real estate. The rating from the Better Business bureau was a d minus. Thats the last publicly available rating in 2010 and it was a result of the number of complaints. Reporter and trump forced to defend a montage of his flipflops throughout the campaign. You change your tune on so many things and that has some people saying, what is his core . Megyn, i have a very strong core. But ive never seen a successful person who wasnt flexible. Reporter the debate coming just hours after former republican president ial nominee mitt romney took on trump in a blistering speech. Donald trump is a phony, a fraud. But you say, wait, wait, wait, isnt he a huge Business Success . Doesnt he know what hes talking about . No, he isnt. And, no, he doesnt. Reporter trump responding to romney right at the top of the debate. He was a failed candidate. Reporter i asked trump if he was worried about the establishment working against him . The establishment is trying to wraesle this nomination away from you. What are you doing to make schauer that doesnt happen. Look, we have a lot of delegates and will have a lot more after this weekend. This ive run the country into hell. Reporter and that moment about trumps hands, Melania Trump telling me senator rubio is desperate in his attacks on her husband. Well, its just desperation. Hes desperate and hes nowhere going in that low attack. Reporter now, senator rubio made the argument at the debate that so far twothirds of voters have voted for somebody other than trump, that a majority of the Republican Voters dont want trump yet. That said and all that talk about a contested convention, all four nominees yesterday said they would support all four candidates said they would support the eventual nominee. Tom, thanks. Republican president ial candidate marco rubio joins us now. Senator rubio, thanks for being here this morning. Good morning. Senator, i wanted to ask you first about the tenor of this campaign. Parents watching, kids watching too. You and donald trump have traded personal insults in recent days and trump responding to your comments about the size of his hands and without going any further, this is a morning show, you have young children. Gone. Look, i regret the way the campaign has become, absolutely, because donald trump for the last year has made it one of the American History offending everyone running for president , jump journalists, the disabled but do you regret look, sometimes when someone is as offensive as he is repeatedly he needs to get a taste of his own medicine. Nothing i have ever said comes anything close to what donald trump says regularly on a daily and routine basis. Let me turn to some of the issues you brought up. You went after him raising concerns about Trump University among other things. You said hes making promises he has no intention of keeping. Hes trying to con people into giving them their vote. Hes trying to con the american voter. Absolutely and hes done this in his business career. What hes done throughout his business career, look, im this successful businessman, i know how to get this done and i can do it for you. Sign up with my brand. Well, thats what hes doing except instead of money hes looking for votes. Changed his position on immigration and at least on one key aspect of immigration. He has no answers on health care. We saw that last week. He had no serious response to Foreign Policy other than to attack me personally by namecalling. There is not a single issue he has ever given a thoughtful, serious answer on and hes asking to become the president of the united states. Senator, you know i think thats evidence of someone you know theres been a lot of talk about this republican revolt from members of the republican establish many. Mitt romney now leading the charge. Romney saying if republicans choose trump as our nominee the prospects for a safe and prosperous future are greatly diminished. A safe future diminished. Do you agree with that. First, i would say its not the republican establishment alone. There are plenty of constitutional conservative, people that believe strongly in the conservative principles who understand he is not a conservative and that could end the end of the modern conservative move many as we know it. The world is a dangerous place and some of the rhetoric that donald trump has and some of the outlined a little bit are reckless and dangerous. But if you think hes going to make america less safe, you think hes conning the american voter, you did say last night that you would support donald trump if hes the nominee, how do you square the two . Yeah, i mean thats the quandary we find ourselves in. Thats what im trying to avoid. If it comes down to that which i dont believe it will then our choice is between Hillary Clinton which is just awful, you know, email investigation that has her own fbi investigation, i think disqualified from being commander in chief because of benghazi and donald trump who is just disgust. I wish people would have a better choice. Youre aware of the primary in your home state donald trump leading. Is it a must win for you. Were going to win florida and, you know, polling, i dont believe i know that poll is not accurate. I know for a fact. That said, you know, we were down 20 points in virginia and almost basically beat him, would have had there been less people on the ballot. Very strong listen, no, ive never categorized any state as must win but well win florida and im very confident of that. All right, senator rubio, we can hear your voice hoarse this morning. We hope you feel better. Thank you. All right, david, thank you. For more on the Republican Debate and the impact of mitt romneys speech we bring in abcs matthew dowd, what a night, what a week, what a year its been. How about last night, anything to change the momentum from donald trump. One would have thought the behavior as we went from a stage that had the size of a nascar race to a Football Team to a Baseball Team to a Basketball Team and now to a golf foursome we certainly didnt have golf etiquette on the stage last night. I dont think it changes anything really because fundamentally many people are going are turned off by it so wont change their vote. It keeps doing this, it prevents donald trump, his behavior and not having really the answers he needs to have prevents him from expanding his lead hes able to coalesce the party which is why some things are not just personal. They are issue based, say Trump University. Anything like that stick . I dont think in the course of last night. People were sort of lost in the conversation last night. I think the only way that sticks is if the issue is framed in person, not by elected officials but by people impacted so if they have that, then they can stick to it. If its elected officials it wont work. You have thoughts about mitt romneys speech yesterday. I think the problem with mitt romneys speech is that hes a flawed messenger. Good guy, flawed messenger. If you took the dictionary and looked up establishment mitt romneys picture was there and that benefits donald trump. All right, always, matt, thank you. Thanks. Now to a big headline this morning about north korea and reports that kim jongun has ordered Nuclear Weapons to be made ready for use. The white house now responding this morning.
