Columbia University disciplined dozens of students this week after its Judicial Board investigated pro-Palestinian demonstrations at Butler Library this year and at another campus location last year.

The school announced discipline Tuesday for two pro-Palestinian protests but did not specify how many demonstrators had been punished.

Columbia was at the forefront of U.S. campus protests over the war in spring 2024. Pro-Palestinian demonstrators set up an encampment and seized a campus building in April, leading to dozens of arrests and inspiring a wave of similar protests nationally.
