Megyn Kelly addressed her feud with Donald Trump in a taped interview, admitting that the billionaire businessman is “so effective” at what he does — but said he could be even better if he toned down his brash behavior.

“If he could pull himself back in just somewhat, he would be so effective,” the Fox News anchor told Charlie Rose in a clip of an interview that will air this weekend on “CBS Sunday Morning.”

“He’s already so effective, he could be so much more effective.”

Rose asked Kelly if the friction between her and the GOP front-runner really began in August of 2015, when she asked him a pointed question during the first primary debate about sexist remarks he’s made.

“Yes, it did,” she said. “Clearly, because Trump and I didn’t really have a relationship at all prior to that.”

As for the vitriol she seems to inspire in Trump, Kelly chalked it up to the mogul hating that he can’t manipulate what she says on her show or during debates.

“I think it’s very clear to him that he cannot control the editorial on my show, or from me, in a debate or other setting,” she said.

“Just that? That’s all it is?” Rose asked.

“I wouldn’t want to speculate beyond that,” “The Kelly File” host replied.

Despite the bad blood between them, Kelly said she’d have him on her show in a heartbeat.

“This conversation airs on Sunday. If on Monday Donald Trump says I want to come on your show, would you say you’re welcome, come on, we have a spot for you?” Rose asked.

“Absolutely,” she said.

And she conceded that Trump has given her more exposure.

“One of our baby sitters is from Peru,” Kelly explained. “And she came home one day and told us that she saw my name in the Peruvian papers. I don’t think that ever happened before this particular dustup. So I’m gonna have to give him that point. I certainly think it’s gotten me much more exposure.”

The anchor also said she understands why Trump could never be banned from Fox News, despite the insults he’s been slinging at her.

“What he really wants is oxygen, you know, he wants television time,” Kelly said.

“So the only thing that is really meaningful to him, the only consequence that would actually have an effect on him, we cannot enact because it would be insane. You cannot ban the presidential front runner from a channel.”

Asked if anything about this campaign season has made her think politics has “gone crazy” in America, she said, “I think one of the unfortunate things we’ve seen this go-around is a coarsening of the culture.”

“We’ve seen it in our politics in 2016, and listen, it was never a tea party here,” she continued.
