An executive order from President Trump promoting a federal crackdown on campus antisemitism and his threats to cancel visas of pro-Palestinian international students have put California university leaders and activists on alert after many of the nation's largest and most contentious protests unfolded at their schools.

The Department of Education is launching an investigation into U.S. universities “where widespread antisemitic harassment has been reported."

Northwestern University and four other schools are under investigation by the U.S. Department of Education for what the federal agency is calling “widespread antisemitic harassment” after mass student protests that broke out last spring against the Israel-Hamas war.
