Federal agents searched two student residences at Columbia University, its interim president said, a week after immigration agents detained Mahmoud Khalil, a leader of last year's campus protests, who the Trump administration wants to deport.

Federal agents arrested Mahmoud Khalil, a Palestinian student who played a major role in last year's protests at Columbia University, students said.

The Trump administration has told Columbia University that it must make a series of policy changes as a precondition for talks on restoring $400 million in canceled federal contracts and grants, ratcheting up its crackdown on the school and others where pro-Palestinian protests flourished last year.
