Mahmoud Khalil, a recent Columbia graduate and Palestinian who is in the country legally and holds a green card, was arrested by ICE over his role in pro-Palestinian activism.

A Palestinian protest leader at Columbia University was arrested by Department of Homeland Security agents Saturday night despite having a green card, his attorney said. President Donald Trump has promised to deport international students who participated in “pro-jihadist protests” on college campuses.

Mahmoud Khalil's attorneys are challenging his arrest, which raises questions about First Amendment protections for non-citizen protesters.

Federal immigration authorities arrested a Palestinian graduate student who played a prominent role in last spring’s anti-Israel protests at Columbia University, according to his attorney.

Protests are growing in New York after the ICE arrest of a Palestinian activist over the weekend. President Trump says his arrest is in direct response to the campus protests at Columbia University last year.

Nationwide protests are planned this weekend after Mahmoud Khalil, a former Columbia University student activist, was arrested by immigration authorities, fueling tensions between the Trump administration and student movements over immigration policy.

The action came less than a week after Mahmoud Khalil, a recent Columbia graduate and a prominent figure in campus demonstrations, was arrested.
