President Donald Trump's administration has escalated its ongoing battle with Harvard, threatening to revoke the university’s ability to host international students, who make up 27% of the campus.

The Department of Homeland Security Secretary also announced the termination of two grants totaling more than $2.7 million to Harvard.

The Trump administration on Monday froze $2.2 billion in federal funding for Harvard after the school refused to agree to a list of White House demands.
