The anti-Trump "resistance" appears to be turning on itself.

On Thurdsay morning, in a rare example of the antipathy many journalists feels torward "Fire and Fire" author Michael Wolff, MSNBC co-host Mika Brzezinski abruptly cut off her interview with Wolff on Morning Joe, after the author of the scandalous, if largely fictional, "tell all" book of the Trump presidency, said he never suggested that U.N. Ambassador Nikki Haley had an affair with President Donald Trump.

To that Brzezinski replied, "You might be having a fun time playing a little game dancing around this, but you’re slurring a woman. It’s disgraceful."

"We're done" the Morning Joe then cut off the interview after asking, with a straight face, "are you kidding? you're on the set of Morning Joe, we don't BS here."

The exchange comes after Wolff recently appeared on Real Time With Bill Maher, where he said he was “absolutely sure” the president was having an affair with someone, and alluded to who that person was in one paragraph of his White House tell-all—that person being Haley, according to the Daily Beast. In the following days, Haley - a former South Carolina governor - has vehemently denied any relationship with Trump.

Minutes after Wolff was kicked off, he tweeted: “My bad, the President is right about Mika"...

... followed by: "The last time I was on Morning Joe off camera Joe and Mika eager to gossip about who Trump might be sleeping with."

In more tweets, Wolff said, "It really would be hard to gossip more eagerly off camera than Mika and Joe gossip," and "To be invited on a show with the purpose of being thrown off... is the new television."

As a reminder, last summer Trump slammed Mika for being "low IQ" and "crazy" among other things.

I heard poorly rated @Morning_Joe speaks badly of me (don't watch anymore). Then how come low I.Q. Crazy Mika, along with Psycho Joe, came.. — Donald J. Trump (@realDonaldTrump) June 29, 2017

And this, ladies and gentlemen, is why you shouldn’t give credibility and airtime to a smear merchant https://t.co/Tcur0ec5Lx — Ben Shapiro (@benshapiro) February 1, 2018
