Harvard is the first school to sue the administration after a back-and-forth between President Alan Garber and most of Trump's team.

A judge has ordered a temporary restraining order blocking the Administration from revoking Harvard's certification.

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.

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.

The larger legal battle between Harvard and the Trump administration could raise questions of retaliation versus executive authority.

"... the government can’t pick and choose which information to share based on ideology," a senior staff attorney with the ACLU said.

Harvard and the federal government are locked in a battle that boils down to turning over records on international students. But Harvard says it is also about the First Amendment.

Harvard University sued the Trump administration Friday over its decision to revoke the school’s ability to enroll international students.

Some of Harvard’s sports teams would be virtually wiped out by a Trump administration decision that would make the Ivy League school ineligible for international student visas.

Dr. Jeremy Faust spilled on the words he "never thought" he'd tell someone who considered going to graduate school at the Ivy League institution.
