Immigration enforcement agents on Saturday arrested and detained Mahmoud Khalil, a legal U.S. resident and Palestinian activist.

Mahmoud Khalil, a 29-year-old legal resident of the United States, was arrested and detained by federal agents Sunday, after his green card was revoked by the Trump administration.

A Manhattan federal court is set to hear arguments in a lawsuit challenging the detention of Mahmoud Khalil, a Columbia University graduate student that the Trump Administration is trying to deport over his role in pro-Palestinian protests at the New York City school last year.

Columbia University student Jonas Du discusses the controversial arrest of pro-Palestinian activist Mahmoud Khalil and why he believes logic is on the Trump administration's side.

President Donald Trump is warning that the arrest and possible deportation of a Palestinian activist who helped lead protests at Columbia University will be the first “of many to come” as his administration cracks down on protests against the war in Gaza.

A federal judge heard arguments and issued orders in Mahmoud Khalil's deportation case. The pro-Palestinian activist helped lead the 2024 Columbia University protests against Israel's war in Gaza. CBS News' Katrina Kaufman reports.

The 12 protesters were taken into custody as scores of people rallied outside City Hall Park in lower Manhattan Tuesday evening.

A US judge temporarily blocked the deportation of a Palestinian graduate student at Columbia University who was arrested over the weekend after he led anti-Israel protests at the Ivy League campus.

The government is trying to deport Mahmoud Khalil, a permanent resident and defender of the Palestinian cause, accusing him of siding with terrorists.

A U.S. judge on Wednesday will hold a hearing over a Columbia University student's challenge to his arrest by immigration authorities, a case that has become a flashpoint of the Trump administration's pledge to deport pro-Palestine college activists.
