Columbia University has launched investigations into students who have expressed criticism of Israel, including sending notices to dozens of students for activities such as sharing social media posts and joining protests. The university's new disciplinary committee, the Office of Institutional Equity, has been accused of suppressing protected speech and bowing to pressure from President Donald Trump. The committee has raised concerns among students, faculty, and free speech advocates. Federal agencies have announced they may cut millions of dollars in contracts to the school due to its inaction in the face of harassment of Jewish students.
