Columbia University says it has expelled or suspended some students who took over a campus building during pro-Palestinian protests last spring, and had temporarily revoked the diplomas of some students who have since graduated.

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.

NEW YORK (AP) — Handcuffed and shackled, Mahmoud Khalil was rushed from New York to Louisiana last weekend in a manner that left the outspoken Columbia University graduate student feeling like he was being kidnapped, his lawyers wrote in an updated lawsuit seeking his immediate release.

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.

A top U.S. Justice Department official says the department is investigating whether Columbia University concealed “illegal aliens” on its campus.
