BOSTON (AP) — The federal government says it’s freezing more than $2.2 billion in grants and $60 million in contracts to Harvard University, after the institution said it would defy the Trump administration’s demands to limit activism on campus.

In a letter to Harvard Friday, President Donald Trump’s administration had called for broad government and leadership reforms at the university, as well as changes to its admissions policies. It also demanded the university audit views of diversity on campus, and stop recognizing some student clubs.

The federal government said almost $9 billion in grants and contracts in total were at risk if Harvard did not comply.

On Monday, Harvard President Alan Garber said the university would not bend to the government’s demands.

“The University will not surrender its independence or relinquish its constitutional rights,” Garber said in a letter to the Harvard community. “No government — regardless of which party is in power — should dictate what private universities can teach, whom they can admit and hire, and which areas of study and inquiry they can pursue.”

Hours later, the government froze billions in Harvard’s federal funding — marking the seventh time the Trump administration has taken the step at one of the nation’s most elite colleges.
