Donald Trump and Megyn Kelly exchange awkward pleasantries at GOP debate

Fox News moderator Megyn Kelly and GOP frontrunner Donald Trump on Thursday exchanged their first direct words since the August GOP debate.

After that debate, Trump launched repeated attacks on Kelly, and he refused to appear in a recent Fox News debate hosted by Kelly.

Here was the exchange:

Kelly: "Mr. Trump, hi."

Trump: "Hello."

Kelly: "How you doing?"

Trump: "Nice to be with you, Megyn."

Kelly: "Great to have you here."

Trump: "You're looking well."

Kelly: "As are you."

Kelly then asked Trump about whether the tapes of an off-the-record editorial-board meeting he had with The New York Times contained any contradictions about "the wall" - one of his biggest campaign promises. Since the start of his presidential run, Trump has promised that he'll build a wall along the US-Mexico border and that Mexico will pay for it.

Trump said that, to be fit to be president, you have to be willing to negotiate. But then he added that he's not very flexible about the wall.

He also said that he wouldn't be releasing the tapes.
