Harvard’s leadership has asked a court to stop the Trump administration’s latest attempt to block international students — over a fourth of its student body — from coming to the university, according to a new court filing less than 24 hours after the latest move by President Donald Trump against the university.

A federal judge late Thursday temporarily blocked a proclamation by President Donald Trump that banned foreign students from entering the U.S. to attend Harvard University.

Harvard University expands its lawsuit against the Trump administration, challenging a new proclamation banning new foreign students from the university. A judge temporarily blocks ban on US entry of foreign nationals seeking to study at Harvard.

Harvard University is challenging President Donald Trump’s move to block foreign students from coming to the United States to attend the Ivy League school, calling it illegal retaliation for Harvard’s rejection of White House demands.

Briefly, the Trump DOJ “appeared eager,” as the Times put it, to escalate its bogus civil investigation of the Harvard Law Review for allegedly discriminating against white men into a criminal probe with allegations of obstruction of justice.

The push comes as the White House regroups after a federal judge blocked its move to bar Harvard from enrolling international students.

The president escalated his feud with Harvard on Wednesday by signing an order that deems the entry of the university’s international students into the U.S. a national security threat.

About 25% of Harvard's enrollment consists of international students, and university officials have been pushing back against White House attacks.

"I’d love to have Harvard come back to the table to negotiate with us,” Education Secretary Linda McMahon told ABC News on Wednesday amid the Trump administration's ongoing feud with the university.

The action is the president’s latest attack on the Ivy League school.

A Defense Department official told others in the Trump administration that a $12 million biological threat research grant at Harvard shouldn’t be terminated because of national security risks, according to the school’s latest court filing.
