The presumptive GOP nominee had made a number of harsh remarks aimed at Kelly on his Twitter account following a GOP primary debate in August. The Twitter spree included his retweeting of accounts that had called Kelly crude names such as a "bimbo."
That debate, during which Kelly asked Trump a question about his treatment of women, sparked the Manhattan billionaire's vitriol toward the Fox host.
Asked about his Twitter habits on Tuesday - specifically, some of the crude tweets from other accounts that Trump has promoted on his page - the real-estate magnate said that Kelly would "be amazed at some of the ones I don't retweet."
Kelly interjected, bringing up the tweets chastising her as a bimbo.
"Well, that was a retweet," Trump said. "Did I say that?"
"Many times," Kelly responded.
"Ooh, OK," an uncomfortable-looking Trump responded. "Excuse me."
Then Trump added that the insult was "not the most horrible thing."
"Over your life, Megyn, you've been called a lot worse than that, right?" Trump asked. "Wouldn't you say? You haven't had a life that's that easy?"
