As an activist who led pro-Palestinian protests at Columbia University remains in an immigration center in Louisiana, college students across the country are protesting, believing the federal government is violating his First Amendment rights.

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.
