After Harvard students held an anti-Israel “die-in” at its prestigious business school, the billionaire donor whose name adorns the building next door to the protest site is urging the institution to “do more.”

“I continue to make my views known to administrators at Harvard,” an investor who is a Harvard Business School alumnus, Seth Klarman, tells the Sun. “The environment at Harvard and other college campuses is becoming exceptionally hostile to Jewish students and colleges and universities must do more. This is not a morally ambiguous situation.”
