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

Harvard University received a letter from a federal task force Thursday outlining policy demands tied to nearly $9 billion in federal funding, a university spokesperson told CNN.

The Thursday letter follows an announcement earlier in the week that nearly $9 billion of the school’s federal grants and contracts is under review. The demands include slashing DEI programming and cooperating with law enforcement officials.
