Transcript for Donald Trump on Jeb Bush Attacks: 'I Think He Had No Choice'
Okay, Jon, thanks very much. To Donald Trump right now. Still holding pretty commanding lead in the republican polls, national polls and Iowa. Mr. Trump, thanks for joining us this morning. Boy, you heard Jeb bush yesterday. You're not a conservative, you're more democrat than republican. This is all personal. Is he drawing blood? Well, I think he had really no choice. He's doing very poorly in the polls. He's a very low energy kind of guy and he had to do something so they're spending a lot of money on ads and he has a lot of money from the hedge fund guys from the special interests from lobbyists, he raised over $100 million so they control him totally so he really had no choice, I think, George. He had to go out with an ad and did a very expensive ad and let's see what happens. So far everybody that's attacked me has gone down. He also shows you praising Hillary Clinton in the video. Bottom line, who would be the better president Obama, Jeb bush or Hillary Clinton? Well, I go with the republican. Hillary was absolutely a horrendous secretary of state, probably the worst ever and I would have to go really with the republican. You know, I was obviously very friendly, I was a major business person. You've seen that and I really was very friendly with all politicians. If I'm in New York I was friendly with politicians throughout the United States. I was friendly -- that was my obligation. That was my job to do as what they just -- they turned me into a world class businessman so I had to get along with everybody. I got along with the Clintons and everybody and it was important to do so, but now, you know, you look at Jeb and see what he's doing and it's sort of an interesting thing and I think he probably had no choice. It's probably now going to stop because it seems to be backfiring on him based on the polls, seems to be somewhat backfiring on Jeb. In the video it says -- showed you answering questions saying you have no idea why you're republican. How would you answer that today? Why are you a republican? That was at a time when the republicans were not doing well and, frankly, they had some ideas that were different from my ideas and a lot of people felt that way and many republicans were saying we have no idea why we're republicans. The republicans were not doing well. But right now you say Donald Trump after weeks of attacks. Trump is standing by live to respond. First let's get the latest from Jon Karl and Jon, with trump still rising the bush camp making a big and possibly risky decision. Reporter: Big and risky but Jeb bush is way down in the polls and clearly irritated by Donald Trump. In the war of words Donald tmpru and Jeb bush, Florida governor admits it's getting personal. It's all personal for him, sure. Mischaracterry sayings of my views. Reporter: Bush is firing back not just in English but in Spanish. Accusing trump of vilifying anyone who disagrees with him. Reporter: Now the bush campaign is throwing trump's S rrdachtigk bt a him. Portraying disassociate yourself from every company that creates jobs -- I want to prohibit them but create jobs here. We need jobs in the united States, George. We don't need jobs in Mexico. We don't need jobs in China. China is eating our lunch, Mexico is eating our lunch. We need jobs here. We need plants built right here in the United States. We don't need them built in Mexico. We don't need them built in China. That doesn't help us despite what some people will try and tell you that it does. Believe me, it doesn't. I'll have jobs in the united States. I'm going to win the hispanic vote because I'm going to create jobs and I've already, if you look at polls with the hispanics I'm winning in many polls with hispanics which some people are surprised at. I'm not surprised at. But yes or no, will you dissociate from any companies or partners of yours that do business in China or Mexico? I wouldn't do that. I want to do business with them. I'm a free trader. The problem with free trade you have to have smart leaders on our side. We do not have smart leaders. We do not have good negotiators. Everything we negotiate is bad including the Iran deal. That deal is one of the worst negotiated transactions I've ever witnessed in my entire life. It's negotiated by people that are either stupid, incompetent, there's something wrong a deal that's absolutely insane. So we have bad negotiators on that we have bad negotiators on trade. If I win we're going to turn it around and bring jobs back to this country and have a lot of convict instead of always losing. Always opinionated Donald Trump, thank you for joining us this morning. Thank you very much.
