Donald Trump admits his campaign regrets in interview with Megyn Kelly

Donald Trump sat down with Megyn Kelly for the first time following months of relentless attacks by the presumptive GOP presidential candidate against the Fox News personality.

The two wasted no time getting down to business Tuesday night on Megyn Kelly Presents.

"I have great respect for you that you were able to call me and say, 'Let's get together and let's talk,'" he said.

Trump said he has regrets about the way he acted during his campaign but he did not elaborate.

Trump never apologized for anything he said about Kelly, but did say he wanted to put the contentious past behind him. Kelly joked that was a good thing because he now has her cell phone number.

Trump had an axe to grind with Kelly ever since the first GOP primary presidential debate last year when she, in his opinion, showed a bias against him with her first question about his sexist statements over the years.

"I thought it was unfair," he told Kelly Tuesday night.

Since that time, Trump launched an all-out verbal assault on Kelly in interviews and over social media, calling her "crazy," among other terms.

Trump told Kelly after the success he felt following the first debate on Fox News, he realized he could actually become president.

Trump told Kelly he was disappointed some of his social media followers said vile comment to Kelly.

"The thing that gets me in trouble is the re-tweets," Trump said about social media backlash he has faced during his campaign.

As far as being called a "bimbo," Trump told Kelly "over your life Megyn, you've been called a lot worse."

Kelly has said it was not easy holding back while talking the bombardment, but she wanted to remain professional.

Trump talked about the death of his brother and his previous marriages. He told Kelly he put more time and work into his businesses and not as much into his relationships, which is why they failed.

Trump was live-tweeting during the primetime interview, which aired on Fox. The hour-long special also welcomed guests Michael Douglas, Laverne Cox and former O.J. Simpson attorney Robert Shapiro.
