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.

Trump’s proclamation marked his administration’s latest attempt to cut off Harvard from a quarter of its student body.

Since its initial criticism of Harvard as a place where antisemitism was condoned or ignored during last spring’s pro-Palestinian protests, the government’s list of complaints about the nation’s oldest and wealthiest university has grown by the day.

President Donald Trump ramped up his campaign against top US universities Wednesday, banning visas for all foreign students coming to attend Harvard and threatening to strip Columbia of its academic accreditation.
