University of Pennsylvania President Liz Magill and board chair Scott Bok resigned after coming under intense pressure from alumni, donors and lawmakers amid an escalating row over antisemitism on campus.

Magill’s departure was announced in a statement by Bok on Saturday. He then issued his own message emphasizing that Magill is not the “slightest bit antisemitic” and making clear that she was exhausted by relentless external attacks when she testified before Congress on Dec. 5 in a widely criticized performance.
