MSNBC's Mika Brzezinski abruptly ended an interview with author Michael Wolff after he refused to take responsibility for hinting that UN ambassador Nikki Haley was having an affair with President Donald Trump.
The author of "Fire and Fury" appeared Thursday on "Morning Joe," where he discussed a new report about Steve Bannon and Hope Hicks discussing Donald Trump Jr.'s meeting with Russians -- which Wolff witnessed himself.
"At one point she and Bannon had a screaming fight, and it was sort of about Bannon said to her, 'If you don't go and get a lawyer now, I'm going to call your father and make him get you one,'" Wolff said.
He said Bannon, who has been subpoenaed by special counsel Robert Mueller, knew everything going on in the White House -- and then Republican political strategist Susan Del Percio changed the subject to Haley.
"You said you believed it was true but you had no proof that the president had an affair with someone in his administration," Del Percio said, and Wolff agreed. "Then you kind of led and indicated that if you follow the bread crumbs you can figure out who it was. After a lot of rumors came out, it was speculation that you meant Nikki Haley, and you said, 'She's embraced it.' Don't you find it irresponsible at this point in time, where we are as a society, when you're talking about a woman who's a high-profile woman in the Trump administration to go after her without any evidence, without any facts, it just seems that it is so irresponsible."
Wolff insisted he hadn't accused her of having an affair with the president, but he said it was "puzzling" Haley would deny the relationship -- and that's when Brezinski stepped in.
"I'm going to go as far as to say you might be having a fun time playing a little game dancing around this, but you're slurring a woman -- it's disgraceful," Brzezinski said.
Wolff again insisted Haley had been accused of nothing but still denied the affair, but Brzezinski wasn't buying it.
"Are you kidding me? You're on the set of 'Morning Joe' -- we don't BS here," she said.
Atlantic editor Jeffrey Goldberg asked whether Wolff had used ambiguous language to hint at the affair, and the author asked them to read what he'd written or said to suggest that.
"Are you kidding? I'm not reading you anything," Brzezinski said. "If you don't get what we're talking about -- I'm sorry, this is awkward. You're here on the set with us, but we're done. Michael Wolff, thank you. We're going to go to break now. Bye, everyone."
Wolff snapped back at Brzezinski a short time later on Twitter.
