NEW YORK (AP) — Columbia University announced disciplinary action Tuesday against students who participated in apro-Palestinian demonstrationinside the Ivy League school's main library before final exams in May and an encampment during alumni weekend last year. A student activist group said nearly 80 students were told they have been suspended for one to three years or expelled. The sanctions issued by a university judicial board also include probation and degree revocations, Columbia said in a statement. The action comes as the Manhattanuniversity is negotiatingwith PresidentDonald Trump's administration to restore $400 million in federal funding it has withheld from the Ivy League school over its handling of student protests against the war in Gaza. The administrationpulled the funding, canceling grants and contracts, in March because of what it described as the university's failure to squelch antisemitism on campus during theIsrael-Hamas warthat began in October 2023. Columbia has since agreed to aseries of demandslaid out by the Republican administration, including overhauling the university's student disciplinary process and adopting a new definition of antisemitism. "Our institution must focus on delivering on its academic mission for our community," the university said Tuesday. "And to create a thriving academic community, there must be respect for each other and the institution's fundamental work, policies, and rules. Disruptions to academic activities are in violation of University policies and Rules, and such violations will necessarily generate consequences." It did not disclose the names of the students who were disciplined. Columbia in May said it wouldlay off nearly 180 staffersand scale back research in response to the loss of funding. Those receiving nonrenewal or termination notices represent about 20% of the employees funded in some manner by the terminated federal grants, the university said. A student activist group said the newly announced disciplinary action exceeds sentencing precedent for prior protests. Suspended students would be required to submit apologies in order to be allowed back on campus or face expulsion, the group said, something some students will refuse to do. "We will not be deterred. We are committed to the struggle for Palestinian liberation," Columbia University Apartheid Divest said in a statement. Columbia was at the forefront of U.S. campus protests over the war in spring 2024. Pro-Palestinian demonstrators set upan encampmentand seized a campus building in April, leading to dozens of arrests and inspiring awave of similar protestsnationally. Since returning to the White House in January, Trump hascut fundingto several top U.S. universities he viewed as too tolerant of antisemitism. The administration has also cracked down on individual student protesters. Columbia University graduate studentMahmoud Khalil, a legal U.S. resident with no criminal record, was detained in March over his participation in pro-Palestinian demonstrations. He is nowsuing the Trump administration, alleging he was falsely imprisoned, maliciously prosecuted and smeared as an antisemite.
