Organizers and supporters of pro-Palestinian demonstrations at Columbia University are being sued for allegedly functioning as Hamas's 'propaganda arm' and 'in-house public relations firm' in New York City and on campus. The lawsuit was filed by victims of Hamas's October 2023 attack on Israel and two individuals affiliated with Columbia who reported mistreatment. The plaintiffs accuse the defendants of coordinating their efforts with Hamas to further its attacks. The civil lawsuit accuses the defendants of violating US antiterrorism law and seeks unspecified compensatory, punitive, and triple damages.
