Harvard University is refusing to comply with a series of demands from the Trump administration, potentially risking billions in federal funding.

In a letter on Monday, Harvard University President Alan Garber said the school “will not surrender its independence or relinquish its constitutional rights” by agreeing to a series of terms proposed by the Trump administration.

The Trump administration demanded Harvard end its diversity, equity and inclusion programs, adopt merit-based admissions and cooperate with immigration authorities — or risk losing $9 billion in federal funding. Garber at the time said the loss of funding would “halt life-saving research.”

Harvard’s rejection of Trump’s demands marks the first time a majority university has pushed back against funding threats made by the Trump administration.
