The U.S. Justice Department is investigating whether Columbia University concealed “illegal aliens” on its campus, one of its top officials said Friday, as the Trump administration intensified its campaign to deport foreigners who participated in pro-Palestinian demonstrations at the school last year.
Agents with the Department of Homeland Security searched two university residences with a warrant Thursday evening. No one was arrested, and it was unclear whom the authorities were searching for, but by Friday afternoon U.S. officials had announced developments related to two people they had pursued in connection with the demonstrations.
