The Department of Homeland Security said a Columbia University student who had her student visa revoked self-deported.

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.

The US Justice Department is investigating whether individuals involved in the pro-Palestinian protests at Columbia University last year violated federal anti-terrorism laws, Deputy Attorney General Todd Blanche announced Friday.
