The Trump administration is tightening its grip on efforts to quash pro-Palestinian demonstrations on college campuses, even as a protest over the detention of activist Mahmoud Khalil flared at the president’s New York City residence and resistance efforts continue in the courts and beyond.

Mahmoud Khalil, an Algerian citizen of Palestinian descent and a US green card holder, is facing deportation after being arrested by federal immigration officials on March 8.A leader of student protests at Columbia University,

In a campus-wide email, Columbia University said a judicial board had ordered action against students who occupied Hamilton Hall in 2024 to protest the war.

Mahmoud Khalil, one of the most prominent faces in the campus's protest movement that erupted in response to Israel's conduct of the war, was arrested Saturday, the Student Workers of Columbia union said.

Columbia University on Thursday said it had doled out a range of punishments to students who occupied a campus building last spring during pro-Palestinian protests. The announcement came a week after President Donald Trump's administration announced that it had canceled $400 million in federal grants and contracts in response to what it said was the Ivy League school's poor response to antisemitism on campus.

Mahmoud Khalil, a permanent US resident who hasn’t been charged with breaking any laws, was arrested outside his apartment and faces deportation.

Demonstrators from a Jewish group filled the lobby of Trump Tower on Thursday to denounce the immigration arrest of a Columbia University activist who helped lead student protests on the Manhattan campus against Israel's war in Gaza.
