A U.S. judge on Friday temporarily blocked the Trump administration from revoking Harvard University's ability to enroll foreign students, a policy the Ivy League school called part of President Donald Trump's broader effort to retaliate against it for refusing to "surrender its academic independence.

Harvard University is challenging the Trump administration's decision to bar the Ivy League school from enrolling foreign students, calling it unconstitutional retaliation for defying the White House's political demands. It is the school's second suit against the Trump administration.

The Administration’s move is the latest escalation in its attack on elite universities across the U.S., with heavy penalties levied on Harvard, including a threat to revoke the university’s tax-exempt status. Those penalties have only grown more severe as Harvard has refused to capitulate to the Administration’s demands.
