Harvard University professors are suing to block the Trump administration's review of nearly $9 billion in federal contracts and grants awarded to the Ivy League school as part of a crackdown on what it says is antisemitism on college campuses.

The Harvard faculty chapter of the American Association of University Professors, along with the national organization, filed a lawsuit on Friday against the Trump administration over its demanded policy changes while reviewing nearly $9 billion in federal funding.

In a letter last week, the government listed conditions that Harvard must meet to receive federal money, including a ban on protesters wearing masks.
