Between classes, when throngs of students stream into and out of Columbia University’s campus, the security lines can back up like a TSA checkpoint. There’s a switch-back path of metal fencing that leads into a white tent, where two sets of guards check and then swipe campus ID cards before letting students in and out.

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.

The discipline includes “multi-year suspensions, temporary degree revocations, and expulsions,” according to the school.
