A U.S. judge on Thursday ordered another block on President Donald Trump's repeated efforts to ban foreign students from attending Harvard University.

In a court order, U.S. District Judge Allison D. Burroughs blocked Trump's latest proclamation aiming to bar new Harvard international students from entering the country, saying the university had shown that without a restraining order it risked sustaining "immediate and irreparable injury before there is an opportunity to hear from all parties."
