Khalil’s arrest casts Columbia University into the spotlight almost a year after protesters set up an encampment on the Ivy League school’s lawn to protest the war, sparking a nationwide movement on campuses across the country. It also signals the Trump administration’s escalating approach to pro-Palestinian activism on college campuses.

Federal agencies canceled $400 million in grants and contracts to Columbia University over failure to address antisemitic harassment during pro-Palestine protests.

U.S. President Donald Trump said on Monday that the arrest of a Palestinian graduate student who has played a prominent role in pro-Palestinian protests at New York's Columbia University will be followed by others.
