Columbia University handed down sanction decisions for student protesters who occupied Hamilton Hall in April of last year, the university announced in a statement Thursday.

The sanctions come as the university faces crippling attacks from the Trump administration over its handling of the protests last year, including the loss of $400 million in federal funding, which could lead to mass layoffs and program cuts.

The university has not released the names of affected students, nor more details about how many will be expelled or suspended.

The punishments, determined by the university judiciary board, are unusually harsh, ranging from multiyear suspensions and expulsions to temporary degree revocations for graduates, according to the email. While occupying the building—which students renamed Hind Hall in honor of a 5-year-old Palestinian girl killed by Israeli soldiers—students damaged property and broke windows. 

Last year, only a few of the students who occupied the building were punished, and most remained in good standing with the university, according to documents the university gave to Congress last year. Of the 22 students who occupied the hall, only three received sanctions, the most severe being short-term suspension. At the time, Columbia said the disciplinary process was “ongoing for many students.”

University spokespeople told Inside Higher Ed that the decisions were the culmination of a months-long investigation. For all other student protests last spring, the judiciary board “recognized previously imposed disciplinary action,” according to the email.

Last weekend, Columbia graduate and legal U.S. permanent resident Mahmoud Khalil was arrested and threatened with deportation for his role in the pro-Palestine protests. Yesterday, Khalil sued the university, along with Barnard College, for allegedly sharing private student disciplinary records with members of Congress and other third-party groups.
