Transcript for Rudy Giuliani Reacts to Donald Trump Firestorm

Okay, Tom, thanks. One of Donald Trump's top supporters. Rudy Giuliani. Hi. Thanks, George. You heard the speaker saying this is a joke gone bad. Apologize. Well, first of all, I was there and I'd like people at home to kind of get an idea what happened in the presidential campaign. What he said is that they should vote against her. He never used -- He was talking about after the election. He was talking about the election in general. He wasn't talking about after the election. You know how speeches go. He was talking about how they have the power to keep her out of office. That's what he was talking about. That is what -- Jem but specifically he was talking about he can't do anything after the election except the second amendment people. We know Donald Trump is not particularly indirect. If Donald Trump was going to say something like that he would say something like that. I was there. I'd like the people at home to realize that the first time that any of us had any idea that that is way it was interpreted is when the Clinton spin machine interpreted it that way, spun it out to a press that is willing to hit him every day, bang, bang, bang, bang, bang. But in realtime you had people like Michael Hayden raising the same question. It wasn't in realtime. The Clinton spin machine spun it out in eight minute, bam, like that. That is not what he intended. What he intended is very, very simple, that he should vote against her. With a crowd like that if that's what they thought he meant -- We did see that one guy -- Which brings me to the guy behind Hillary Clinton who is the father of a person who killed 49 people who wounded 53 people, ends up being invited to sit in a prime position behind Hillary Clinton and you got to ask yourself, number one, who invited him? We still don't know and, number two, what drew him -- They said they didn't invite him and disavowed -- Why is he such a big supporter holding up a sign about how great a president she would be. He supports the Taliban. He is anti-american who himself has supported terrorist organizations who has said that god is going to punish homosexuals. He is a homophobe of the worst kind and he is a very, very radical islamic extremist. What's drawing him to Hillary Clinton? People should ask that question. What brings him to Hillary Clinton? I believe it's her soft stance on islamic extremist terrorism, which he and -- which she and the president have had since the president has been in office. He shows up at her rally. She disavows that supporters. You have 50 national security officials in the republican administration say they cannot support Donald Trump because he lacks self-control. Would be the most reckless president in American history including people you supported strongly in the past. Michael chertoff, Tom ridge, former homeland security secretary, these are not democrats. These are not Clinton supporters. These people are worried about Donald Trump. Well, first of all, there are some of them that I respect a lot and they're good friends of mine and will remain good friends of mine but I have a disagreement with them. They don't know Donald Trump the way I do. I've known him for 28 years. I know he is a responsible man, successful man who achieved a great deal and can be trusted much better than Hillary Clinton who has found to be extremely careless with the use of national security information, extremely careless is like, oh, gosh, the kindest way you could say it. E-mail after e-mail is spilling out one after another after another and we still have 30,000 that she destroyed. Now, and -- what I suspected is true. What I suspected is that she destroyed a lot of those e-mails because it shows a connection between Hillary Clinton as secretary of state and the money being raised for the foundation and bill Clinton speaking fees. Doesn't Donald Trump have to get more careful with his words if you want to get that message out. No, you have to stop misinterpreting and stop putting words in his mouth that he didn't say, that he didn't mean. I drove from that venue to the plane, got on the plane, I was with him all throughout. He had no idea that anybody would interpret his words that way, that is not the way he meant it. It was a big surprise. My first reaction when I heard the call was, oh, this will go away in a minute. Such a stupid thing to suggest that he would say something like that, and it was so obvious to all of us what he meant. Mr. Mayor, thanks for joining us this morning.
