President Donald Trump’s administration has canceled grants and contracts totaling $400 million to Columbia University in New York City due to “inaction in the face of persistent harassment of Jewish students,” the General Services Administration said Friday.

The U.S. government said the canceled funds would come out of $5 billion in grants committed to Columbia, the GSA said in a joint statement with the Department of Justice, the Department of Education and the Department of Health and Human Services.

Columbia has been at the center of college protests in which demonstrators demanded an end to U.S. support for Israel due to the civilian deaths and humanitarian crisis in Gaza.

There were allegations of antisemitism and Islamophobia in protests and counter-protests. Columbia has previously said it made efforts to tackle antisemitism.

“Canceling these taxpayer funds is our strongest signal yet that the federal government is not going to be party to an educational institution like Columbia that does not protect Jewish students and staff,” said Leo Terrell, who leads the Justice Department’s antisemitism task force.

It was not immediately clear which grants and contracts were being cut.
