Nationals from seven countries on the Trump Administration's temporary travel ban are rushing to try and enter the U.S. again, hoping to make it through a narrow window opened by legal challenges. The federal appeals court in San Francisco denied the U.S. Justice Department's effort to immediately reinstate the measure on accepting certain travelers and all refugees early Sunday. For now, it remains blocked by a judge's temporary restraining order, and federal officials have told their staffs to comply. Advocates were not taking any chances, telling people who could travel to get on the earliest flights they could find after the week-old restriction was blocked Friday by U.S. District Judge James Robart in Seattle."We're telling them to get on the quickest flight ASAP," said Rula Aoun, director of the Arab American Civil Rights League in Dearborn, Michigan. Her group sued in federal court in Detroit, challenging Doanld Trump's executive order as unconstitutional even though U.S. Code section 8 U.S. 1182 grants authority to the president to impose restrictions for a "period as he shall deem necessary, suspend the entry of all aliens or any class of aliens as immigrants or non-immigrants, or impose on the entry of aliens any restrictions he may deem to be appropriate."Protesters sought to keep up the pressure, gathering in Denver and other U.S. cities to demonstrate against the measure.
