President Trump‘s controversial travel ban was put on hold over the weekend after a federal judge issued a nationwide temporary order that reopened the flow of travelers from seven predominantly Muslim countries. The order came in response to a lawsuit filed by Washington and Minnesota arguing that the ban amounts to religious discrimination against Muslims in violation of the U.S. Constitution.

The Justice Department appealed the order, saying the judge “second guessed” the president on national security, but early Sunday the U.S. 9th Circuit Court of Appeals denied the administration’s request to immediately reinstate Trump’s travel ban, instead asking both sides to file arguments by Monday.
