Harvard University President Claudine Gay responded to criticism by students and alumni including Bill Ackman that the school isn’t doing enough to protect Jewish students, saying it would expand its diversity program to combat antisemitism.

The Ivy League university has come under intense criticism that started the day of the Oct. 7 Hamas attack on Israel. More than 30 student groups issued a statement that blamed Israel for the attack and not Hamas, which is classified as a terrorist group by the US and European Union.
