The University of Pennsylvania has announced a new interim president on Tuesday, after Liz Magill resigned on Saturday.

Dr.  J. Larry Jameson will serve as the interim president of the university, UPenn announced Tuesday. Previously, Jameson was dean of the university's medical school. 

Magill resigned following criticism stemming from her appearance at a congressional hearing, where she failed to say if calls for the genocide of Jews would violate university policy.

"I write to share that J. Larry Jameson, MD, Ph.D., has graciously agreed to serve as Interim President of the University of Pennsylvania, effective immediately. Dr. Jameson has served as Executive Vice President of the University of Pennsylvania for the Health System and dean of the Raymond and Ruth Perelman School of Medicine, which together comprise Penn Medicine, since 2011," Interim Board of Trustees Chair Julie Beren Platt wrote in a statement Tuesday. "Jonathan A. Epstein, MD, executive vice dean and chief scientific officer of the Perelman School of Medicine and senior vice president and chief scientific officer of the University of Pennsylvania Health System, will step in as Interim Executive Vice President for the Health System and dean of the Perelman School of Medicine.

"Penn is fortunate to have the benefit of Dr. Jameson’s experience and leadership during this time of transition.

Magill resigned following a congressional hearing on Dec. 5, where she gave a non-answer to New York Republican Rep. Elise Stefanik's question asking if, "calling for the genocide of Jews violate[s] Penn’s rules or code of conduct? Yes or no?"

"If the speech turns into conduct, it can be harassment, yes," Magill responded, later adding, "It is a context-dependent decision."

"This is unacceptable. Ms. Magill, I’m gonna give you one more opportunity for the world to see your answer. Does calling for the genocide of Jews violate Penn’s code of conduct when it comes to bullying and harassment? Yes or no?" Stefanik then asked.

"There was a moment during yesterday's congressional hearing on antisemitism when I was asked if a call for the genocide of Jewish people on our campus would violate our policies. In that moment, I was focused on our university's long-standing policies aligned with the U.S. Constitution, which says that speech alone is not punishable," Magill said. "I was not focused on, but I should have been, on the irrefutable fact that a call for genocide of Jewish people is a call for some of the most terrible violence human beings can perpetrate."
