Columbia University is investigating students who have expressed criticism of Israel, with cases ranging from sharing social media posts to hosting off-campus art exhibitions. The new disciplinary committee, the Office of Institutional Equity, has sent notices to dozens of students and is raising concerns among students, faculty, and free speech advocates. The university is under financial pressure after federal agencies announced they would consider cutting contracts and grants due to its inaction in the face of harassment of Jewish students. House Republicans have also launched a review of Columbia's disciplinary process.
