On Monday evening, the Department of Justice filed a 15-page brief defending President Trump’s executive order on immigration, and moments later, it was announced the 9th Circuit Court of Appeals will hear a challenge to his travel ban on Tuesday. Last week, a federal judge temporarily suspended parts of the travel ban against people from seven Muslim-majority countries. On Tuesday, the 9th Circuit Court of Appeals will listen to oral arguments during a hearing conducted by telephone at 6 p.m. ET to decide the fate of the restraining order. The attorneys general of Washington and Minnesota have both challenged Trump’s executive order, and say if the temporary suspension is lifted, “chaos” will ensue at airports across the United States.
