Harvard University is locked in a legal battle with the Trump administration after being barred from enrolling international students. Homeland Security cited national security risks, prompting Harvard to sue.

In a move that has drawn sharp criticism from academic institutions and civil liberties groups across the United States, the Trump administration has initiated a legal and administrative process aimed at revoking Harvard University’s ability to admit international students.

Before a judge temporarily blocked Trump’s ban on Harvard enrolling foreign students, China warned that the move would “damage” America’s image.
