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.

Immigration officials have arrested a second person who participated in Pro-Palestinian protests at Columbia University, and have revoked the visa of another student

The US Justice Department is investigating whether individuals involved in the pro-Palestinian protests at Columbia University last year violated federal anti-terrorism laws, Deputy Attorney General Todd Blanche announced Friday.

New video shows the arrest of Columbia University pro-Palestinian activist Mahmoud Khalil by Immigrations and Custom Enforcement agents.

The arrest of a student protester raises questions on free speech. Is the White House picking which speech is illegal, or are they enforcing anti-discrimination laws?

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.

At least 100 people planned to be arrested as a form of protest against the detainment of Columbia University student, Mahmoud Khalil.

Columbia said it had temporarily revoked the diplomas of some students involved in pro-Palestinian demonstrations.
