A federal judge sharply questioned the Trump administration on Monday over its cancellation of $2 billion in federal funds for Harvard University, after the administration cited Harvard’s insufficient efforts to combat antisemitism as the reason for doing so.

Judge Allison Burroughs of the U.S. District Court for the District of Massachusetts held a hearing over competing motions for summary judgment from Harvard and the Justice Department, with both sides attempting to win the first legal battle without a trial. Burroughs, an Obama appointee, heard arguments from both sides but appeared skeptical of the DOJ’s arguments for canceling federal funding to the university.
