Current and former Palestinian students and staff at Columbia University filed a lawsuit in New York alleging the institution failed to protect them from harassment and applied biased disciplinary processes since late 2023. The suit follows campus protests after the October 2023 Hamas attack and Israel's subsequent military operations in Gaza, including the May 2025 suspension of more than 65 students for a library occupation. Columbia University has denied systemic discrimination, condemned hate, and declined to comment on the litigation while facing federal funding cuts from the Trump administration over antisemitism concerns.
