President Donald Trump's administration has threatened to revoke Harvard University's ability to host international students and withdraw its tax-exempt status. The Department of Homeland Security ordered Harvard to turn over records of its foreign student visa holders' activities and canceled two grants to the school. This comes after Harvard became the first university to openly defy the administration's demands related to activism, antisemitism, and diversity. The government has already frozen over $2 billion in grants and contracts to the university.
