The Trump administration is tightening its grip on efforts to quash pro-Palestinian demonstrations on college campuses, even as a protest over the detention of activist Mahmoud Khalil flared at the president’s New York City residence and resistance efforts continue in the courts and beyond.

Leqaa Kordia, a Palestinian from the West Bank, was arrested by immigration officers for overstaying her student visa, the Department of Homeland Security said.

Columbia University announced punishments, including expulsions and suspensions, for students who occupied Hamilton Hall in a pro-Palestinian protest last year.

Columbia University on Thursday said it had doled out a range of punishments to students who occupied a campus building last spring during pro-Palestinian protests. The announcement came a week after President Donald Trump's administration announced that it had canceled $400 million in federal grants and contracts in response to what it said was the Ivy League school's poor response to antisemitism on campus.
