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.
