They are all Republicans. Here is Nick Robertson at The Hill:
A group of six Pennsylvania Republicans called on the University of Pennsylvania (Penn) to fire its president, Liz Magill, following backlash against comments she made at a House committee hearing Tuesday.
At the hearing about antisemitism on college campuses, Magill and other college leaders controversially said that it would depend on context whether comments calling for genocide of Jewish people would be considered harassment.
“President Liz Magill’s actions in front of Congress were an embarrassment to the university, its student body, and its vast network of proud alumni,” Rep. Guy Reschenthaler (R-Pa.) said on X, formerly known as Twitter. “She has shown the entire world that she is either incapable or unwilling to combat antisemitism on the university’s campus and take care of its student body.”
Get some context here. Pennsylvania senators Bob Casey and John Fetterman have also criticized Magill, but as far as I know they have not called for Magill’s resignation.
Here is an interesting piece about why Magill is taking more heat than the Harvard president Claudine Gay and and MIT president Sally Kornbluth.
