Students and professors in Chicago are concerned that President Trump's crackdown on antisemitism on college campuses, including the detention and possible deportation of a Columbia University anti-Israel activist, will have a chilling effect on academia. The activists' arrest has raised fears that universities may feel pressured to crack down on student protests and limit free speech. Critics argue that the detention and possible deportation of the activist is a violation of his First Amendment rights and an attempt to curb speech the Trump administration disagrees with. Secretary of State Marco Rubio has defended the arrest, stating that it is not about free speech but about individuals who do not have a right to be in the United States.
