Columbia University’s interim president resigned from her position at the embattled Ivy League Friday night, just days after she told the Trump administration she would implement a mask ban — while privately promising faculty she would not.

Armstrong — who previously spent 17 years at Penn — assumed the role of interim president after then-Columbia University President and former Penn professor Nemat “Minouche” Shafik resigned in August.

Columbia University appointed a new acting president Friday. Claire Shipman, co-chair of the school's Board of Trustees, will assume the role effective immediately, according to an announcement on the school's website.

According to the Columbia Spectator, Shipman worked at CNN for a decade where she earned a Peabody Award for her coverage of the USSR’s dissolution. After a brief stint at NBC News, she moved to ABC in 2001 to become “Good Morning America’s” senior national correspondent.

Claire Shipman, an award-winning journalist and Columbia alumna, has been appointed acting president of Columbia University following Katrina Armstrong's resignation amid political pressure and a £320 million funding crisis.

University gives no reason for Katrina Armstrong's decision to step aside and return to her previous post, says board of trustees co-chair Claire Shipman to take over for now
