Donald Trump to Megyn Kelly: 'I have regrets'

NEW YORK (FOX 5 NEWS) - Fox News host Megyn Kelly sat down with presumptive Republican nominee Donald Trump in the first edition of "Megyn Kelly Presents" on FOX.

During the interview, they talked about their exchange at the first Republican presidential primary debate last August when Kelly asked Trump about his temperament and his history of calling women he doesn't like "fat pigs," "dogs," "slobs" and other names.

There were some uncomfortable moments in the interview that aired Tuesday night. Kelly said she thought her question during the debate was fair.

"I thought it was unfair. First of all, I didn't think it was really a question," Trump said. "I thought it was more of a statement. That was the first question that I've ever been asked during a debate and I've never debated before. I mean, my whole life is a debate, but I've never actually debated before. So I'm saying to myself 'I've got two hours of this?'"

After the debate question that Trump thought was unfair, he launched an attack on social media against Kelly calling her names, including "bimbo."

"Did I say that?" Trump asked.

"Many times," Kelly said.

"Ooh, OK. Excuse me," Trump said. "Over your life, Megyn, you've been called a lot worse, is that right, wouldn't you say?"

Kelly asked Trump who actually does all of his tweeting on Twitter.

"During the day, if I'm in the office, I have a number of people that I'll just call out a tweet to," Trump said. "After like 7 or 8 o'clock, if I'm home I'll do it myself."

Trump calls the social media attacks a modern-day form of fighting back against someone who he feels has attacked him. 

Kelly said that every topic was on the table; nothing was off limits.

She asked Trump about the insults he has hurled at Sen. John McCain, Carly Fiorina, and Sen. Ted Cruz's wife, Heidi, among others. She asked him if he has any regrets.

"Absolutely I have regrets. I don't think I want to discuss what the regrets are but absolutely I could've done certain things differently," Trump said. "But overall, I have to be very happy with the outcome. If I were soft; if I were presidential, OK, presidential -- in a way it's a bad word because there is 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."

Trump said he views himself as a messenger in this presidential cycle.

And if he doesn't become president?

"I will consider it to be a total and complete waste of time, energy and money," Trump said.
