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.

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

Columbia University has suspended dozens of students and barred alums and others who participated in a pro-Palestinian demonstration inside the school’s main library earlier this week.
