Columbia students reported feeling threatened when masked protesters stormed the campus library, chanted anti-Israel slogans, and mocked the Israeli hostage crisis.

The Trump administration said Thursday it was “encouraged” by Columbia University’s response to a pro-Palestinian protest at the main campus library Wednesday where police took 80 people into custody.

Federal authorities are reviewing the visa status of all those taken into custody, U.S. Secretary of State Marco Rubio said on X.
