A Columbia University student, Ranjani Srinivasan, fled to Canada after federal immigration agents showed up at her apartment searching for her. Srinivasan's student visa had been revoked, and she left the country before the agents could detain her. The Department of Homeland Security later issued a statement accusing Srinivasan of being a terrorist sympathizer, but her lawyers deny the allegations. Srinivasan's case is part of President Trump's crackdown on pro-Palestinian demonstrators, and she is one of several noncitizens targeted at Columbia University.
