Columbia University has announced punishments for students who occupied a campus building during anti-Israel protests, including expulsions and suspensions. The university has faced controversy over the arrest of a student and the revoking of over $400 million in federal grants due to its handling of antisemitism. The punishments were issued by the Columbia University Judicial Board and will take effect after the appeal period. The university has been under scrutiny for antisemitic incidents on campus, including the taking over of Hamilton Hall and the harassment of Jewish students.
