Harvard sued and asked for a restraining order less than 24 hours after the Trump administration had said it would block current and future international students from attending the university.

Some Harvard students have started transferring due to the uncertainty of the feud between the White House and university.

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.
