MSNBC's Mika Brzezinski visited Trump Tower in New York on Tuesday shortly after “Morning Joe” wrapped up its telecast. But why she was there — and with whom she was meeting — was a mystery as she entered the building.

A pool reporter covering President-elect Donald Trump's transition team reported that Brzezinski, who often criticized Trump during the campaign, was cagey about the nature of her call.

“She was asked if the meeting was with PEOTUS, and the response was unclear,” Yahoo national correspondent Hunter Walker reported. “Brzezinski did not respond to a question from your pooler about whether she will be seeing Kellyanne Conway.”

Citing an unnamed source, Politico's Dylan Byers reported Tuesday afternoon that Brzezinski met with Ivanka Trump to discuss Brzezinski's "Know Your Value" seminar series for women.

Brzezinski and co-host Joe Scarborough met with Donald Trump in September, ostensibly to discuss moving past a feud that had intensified over the course of several months. The “Morning Joe” tandem was among the first to treat Trump as a serious contender for the Republican presidential nomination last year, and the real estate executive was a frequent guest on their show early in the campaign.

When Trump won the New Hampshire GOP primary in February, he appeared on the program the following morning to say, “You guys have been supporters, and I really appreciate it.” Trump amended his thanks a moment later: “Not necessarily supporters, but at least believers.”

A turning point came later that month when Scarborough came down hard on Trump's initial refusal to disavow the endorsement of former Ku Klux Klan leader David Duke. The former Republican congressman called Trump's response to Duke's support “disqualifying.”

Brzezinski and Scarborough ramped up their criticisms of Trump from there, and the billionaire reacted by boycotting the show and composing nasty tweets.
