A federal judge has halted President Donald Trump’s latest attempt to block international students from coming to Harvard University. The temporary restraining order issued late Thursday by US District Judge Allison Burroughs came hours after the university urged the judge to step in on an emergency basis to block a proclamation Trump signed a day earlier that suspends international visas for new students.

President Donald Trump is moving to block nearly all foreign students from entering the country to attend Harvard University, his latest attempt to choke the Ivy League school from an international pipeline that accounts for a quarter of the student body.
