Seventeen candidates down and Trump is the last man standing. The presumptive Republican nominee. Let's begin. Thank you for sitting down with me. Thank you very much. My honor. It's been a long nine months. It has been a long time, I agree. I want to ask you about the beginning of your campaign. There had to be a moment on stage at a campaign rally or one night after a win where it occurred to you I could actually be the president. When was that? Well, I think the debates were really a big thing, and not to bring up an unpleasant debate, but even that first debate was pretty amazing and 24 million people watching, a record on cable television, and I think that meant something. I think that first debate meant something because I felt very, very comfortable with the subject and I felt very comfortable with the people I was competing against. Let's talk a little bit about litigation because you have threatened to sue many people in the course of the campaign, but, of course, if you wind up president, you're not going to be able to do that either. Can you go four years without threatening to sue anybody? What China has done to us -- maybe you -- you know, do you have methods of suing countries -- It's going to be a busy law firm. No, no, it's going to be busy, but it's a little different, and it's also a tactic for me. It's a business for me, and I have been successful, and I've, you know, used litigation, and sometimes I use it maybe when I shouldn't and sometimes I don't. Have you made any mistakes in this campaign? You had said publicly you thought the re-tweet about Heidi Cruz was a mistake. Let me just -- Well, I said, I could have done without it to be exact. I could have done without it. You said a mistake. Are you walking that back? No, no. I'm not walking it back but I actually didn't say it that way. I said, I could have done without it. I mean -- [Crosstalk] You shouldn't have done that, right? I wish I didn't do it. Although, you know, I guess you could say she's fair game because she's very much involved with the campaign. But that tweet was about her looks. You know what, I have millions of followers @realDonaldTrump. I have millions of followers. I have millions of Facebook -- I'm familiar. Yes. You are. The thing that gets me in trouble is re-tweets. The re-tweeter is really more of a killer than the tweets. The tweets I seem to do pretty well with. So that is one, the Heidi Cruz thing, let me just give you a list of a couple -- Sure. -- and tell me if you have any regrets on it. The comment about John McCain, you prefer people who were not captured. The comment about Carly Fiorina's face. But do you regret any of those comments? Yes, I guess so, but you have to go forward. You make a mistake, you have to go forward. And, you know, you can correct a mistake, but to look back and say, "Gee whiz I wish I didn't this or that," I don't think that is good, and I don't think in a certain way I don't even think that is healthy. I want to talk a little bit about your family. Your older brother, Fred Jr., was an alcoholic and died at a relatively young age. When I say his name, what does that bring up for you? Well, he was great. He was the most handsome person. He was a really smart guy, really, really smart guy. He had everything. But at a certain age he started drinking a little more, a little more, and ultimately it was a big problem, and he'd say don't ever, ever drink. And I'll tell what you, I never -- I have never had a glass of alcohol -- Never? I have other problems, okay? But -- What are they? Get specific. I don't want to talk to you about that. That I can't talk about. That would be too good. You've been divorced twice. Yes. Did you learn something about relationships, about love, about yourself? Well, you have to put more into it. I put so much into my business that I didn't put enough into the relationship, and I see that. And I have learned that. I mean, I have learned that. Sometimes there's nothing you can do about that because that's the way you are. I mean, if somebody told you that you have to ease up, you can only work half the number of hours that you're working, I don't know if you'd be able to do that. I'd give it a try. But even if they'd say you'd have a better relationship with your husband, I hear it's just great, but you know, I mean, I don't know that you'd be able to do that. Has anyone ever hurt you emotionally? Well, I think the big thing would be maybe the death of my brother. That was, you know, the hardest thing for me to take. It was very tough because, you know, that's natural and he saw a certain potential and he would say, don't ever have a drink. Now, I don't carry that far with people. I never had a drink. But, you know, people can have a drink or they can do it socially, but, you know, that can lead -- You tell me if I'm wrong, I feel like you're trying to get out of bounds on the emotional question to the subject of alcoholism which we discussed. Has it happened that somebody has done something to you, you know, not a death in the family, but has done something to you to wound you? Well, you know, I can say this. It would be something I could certainly think about and, you know, come back with an answer -- No, it's okay. I mean -- But I will say this, when I'm wounded, I go after people hard, okay? And I try and unwound myself. Most kids between the ages of six and 16 have been bullied at some point in their lives. Were you ever bullied? No, I wasn't. But I have seen bullying, and bullying doesn't have to just be as a child. I mean, I know people are bullied when they're 55 years old. It can happen when you're 45. It happens, right? But you've got to get over it, fight back, do whatever you have to do. Let me ask you about that. Because most American parents try to raise their kids to not bully, to not name call, to not tease, not taunt. How can they effectively bring that message when the front-runner for the Republican nomination does all of those things? Well, I do it, really -- you know, I've been saying during this whole campaign, that I'm a counter-puncher. You understand that. I'm responding. Now, I then respond times, maybe, 10. I don't know. I mean, I respond pretty strongly. But in just about all cases, I've been responding to what they did to me. So it's not a one-way street. Let's talk about us. Okay. [Commercial break] Let's talk about us. Okay. We were always friendly. Right. Good relationship. Right? And then came the August 6, 2015 debate and I asked you a tough question about women using only the words that you had used. I thought it was a fair question. Why didn't you? I thought it was unfair. First of all, I didn't think it was really a question. I thought it was more of a statement. That's the first question that I have ever been asked during a debate and I have never debated before. I mean, my whole life is a debate but I never actually debated before and I'm saying to myself, man, what a question. And then of course you have Bret doing his thing. So, I'm saying to myself, I have two hours of this? I don't really blame you because you're doing your thing, but from my standpoint I don't have to like it. Afterwards you said that you didn't feel that the moderators had been nice. But do you think it's the journalist's role to be nice to presidential candidates at a debate? Fair. I don't care if they're nice. You used the word nice. Well, okay, no, I don't think so. I mean, I might have said they weren't nice but that doesn't mean they have to be nice. Uh-hm. You know, it's not a cocktail party. I mean, in a certain way what you did might have been a favor. Because I felt so good about having gotten through -- I said if I can get through this debate with those questions, you can get through anything. You seem to stay angry for months. Was that real or was that strategy? Well, I'm a real person. I don't say, oh, gee, I'm angry tonight but tomorrow you're my best friend. See, I do have a theory -- and this could happen again with us. I mean, it could be even doing this particular interview. I have great respect for you that you were able to call me and say, let's get together and let's talk. To me I would not have done that. I don't say that as, you know, a positive. I think it's a negative for me, and you walk into Trump Tower. We didn't have like on a neutral site or over at Fox or something. That would be a whole different thing and I wouldn't have done it. I think the doormen are still recovering. I think the whole building is recovering. People are going like, this can't be possible. Right? And this is the first you and I have ever discussed what happened between us over the past nine months because you and I did not talk about that in the meeting. No, we didn't discuss it. We didn't discuss it. So, when you look back on the past nine months from that first debate to now, any regrets? Absolutely I have regrets. I don't think I would have discussed what the regrets are but absolutely. I could have done certain things differently. I could have maybe used different language in a couple of instances, but overall I have to be very happy with the outcome. And I think if I didn't conduct myself in the way I have done it, I don't think I would have been successful actually. If I were soft, if I were, you know, presidential, okay, presidential. In a way it's a bad word because there's nothing wrong with being presidential, but if I would not have fought back the way I fought back, I don't think I would have been successful. You're no longer just Donald Trump, businessman or Donald Trump host of "Celebrity Apprentice." Now you're steps away from the presidency. Have you given any thought in this position to the power that your messaging has on the lives of the people you target and on the millions of people who take their cue from you? I have. I have. And I see suffering. I mean, I see tremendous suffering and I understand. I have a very big heart. A lot of people don't understand that, but people that know me do. And we have to take care of our country, and I do feel America first. I mean, America has been fourth and fifth and ninth. I mean -- But you know what I'm saying. When Donald Trump targets somebody and says this person is bad, that person is bad, it creates a firestorm in those people's lives and many of these people are so-called civilians who haven't put themselves out there as public figures. But it's in response to something they did -- But you are so powerful. You are so powerful now. I don't view myself as that. I mean, I view myself as a person that like everybody else is fighting for survival. That's all I view myself as and I really view myself now as somewhat of a messenger. You know, this is a massive thing that's going on. These are millions and millions of people that have been disenfranchised from this country. I was in front of a group yesterday, at least 25,000 people. The place was going crazy, and I said, I'm like the messenger. It's true but they're listening to you, and they're taking their cue from you. So that's the question is whether now so close to the Oval Office, whether you will take that responsibility seriously and change your tone to try to be more unifying and less divisive. I do take it very seriously, and I understand what's going on, and when I see the fervor, when I see 25,000 people that have seats and not one person during an hour speech will sit down, I say sit down everybody, sit down, and they don't sit down, I mean, that's a great compliment but I do understand the power of the message. There's no question about that. I want to talk a minute about the tweeting. Okay. Set the scene for me. Because I know where I was when I was on the receiving end on a lot of those tweets. But I've always wondered where you were. I picture a crushed velvet smoking jacket. You know -- lounge, slippers. Maybe not as fancy as that. Maybe not as fancy as that. Maybe probably a lot less. You said it's you if it's past 7:00 in the evening. This weekend, I picked up 114,000 people. Do you pick up your iPhone and actually tweet yourself? Yes. Usually about 7:00 or 8:00 at night I'll do it myself. But during the day when I'm in the office, I have a number of people that I just call out a tweet to. It's always my right. You call out exclamation point? I do. I say exclamation point. You know me well. You know me well. No, I'll say exclamation point. I'm familiar. So, they'll type is out for me real fast, bring it in. I'll be in a meeting. Put an exclamation point and I'll send it out. So, I don't do the physical. Now after like 7:00 or 8:00 if I'm home, I'll do it myself, and I have fans, you probably learned, and I didn't do it for this reason but when you and I were having our little difficulty, you probably had some pretty nasty tweets sent your way. I don't want to say but I've heard that. I don't want that to happen, but my fans they really love -- we have an unbelievable bond. You re-tweet some of those. Not just the fans. But not the more nasty ones. You would be amazed at the ones I don't re-tweet. Bimbo? Well, that was a re-tweet, yes. Did I say that? Many times. Oh, okay. Excuse me. What do you think with, I mean -- Not the most horrible thing. You know we're getting political. Over your life, Megyn, you've been called a lot worse, wouldn't you say? You know, you have had a life that's not been that easy, and -- Not about me. It's not about me. It's about the messaging. No, no. Young girls and to other women. It's a certain amount of fighting back. You know, it's a modern day form of fighting back. I mean, it really is, but -- Are you going to stop that as president? Well, I'm going to stop it about you now because I think I like our relationship right now, so I'm certainly not going to -- Now you have my cellphone number. That is actually much more efficient. You gave me your cellphone number. And you promised you would not use it for evil. No. I promise. You will never see that. You will never see that. If you don't become president, will this all have been for nothing? Or will you have changed America? So I got a call from a great writer who said to me, congratulations. I said congratulations on what? He said what you have done has never been done before. I said what have I done? And he talked about different things. I said, well, unless I win, I can't do the changes. I can't make America great again. I can't lower taxes and make our military strong and get along with other nations, frankly, that we don't get along with right now but do better with them so, you know, they're not ripping us off like they all are. But I said unless I win, I can't do that. He said, no, no you are wrong, what you have done has never been done before and it will go down in history. And I appreciate -- and I don't want to really talk about it because in case it doesn't work out, I'd rather have that narrative but I'm going to say this, if I don't go all the way and if I don't win, I will consider it to be a total and complete waste of time, energy, and money. Mr. Trump, thank you. Thank you very much. Just fascinating. Thank you very much. I appreciate it. Thanks, Megyn.
