ICE agents arrested Palestinian activist Mahmoud Khalil -- a leader in Columbia University's encampment movement -- on Saturday night, said attorney Amy Greer.

Student protesters at Columbia University criticized the Trump administration's decision to rescind more than $400 million in federal grants to the university as a "scare tactic."

The Trump administration says it’s pulling $400 million from Columbia University. Multiple federal agencies announced Friday that they're canceling grants and contracts because of what the government describes as the Ivy League school’s lackluster efforts to squelch antisemitism on campus.

Columbia University's interim president said the school is working to address the "legitimate concerns" of U.S. President Donald Trump's administration after $400 million of federal government grants and contracts to the university were canceled over allegations of antisemitism on campus.
