Harvard alumnus and hedge fund manager Bill Ackman has called on university president Claudine Gay to take immediate action to address antisemitism on campus. Ackman described the situation as "dire" and expressed concerns about the threat of physical violence against Jewish students. Antisemitic incidents have surged on campuses across the US since the recent conflict in Israel and Palestine, with protests dividing campuses and straining relations. Ackman criticized Harvard's failure to condemn student groups that placed sole responsibility on Israel for the conflict.
