President Trump’s Muslim travel ban has been dealt another legal blow. On Monday, the United States Court of Appeals for the Ninth Circuit unanimously ruled that President Trump had overstepped his legal authority in signing an executive order seeking to ban from entering the United States all refugees and citizens of six majority-Muslim nations. The court wrote, “The order does not offer a sufficient justification to suspend the entry of more than 180 million people on the basis of nationality. National security is not a 'talismanic incantation' that, once invoked, can support any and all exercise of executive power.” In its opinion, the court also cited Trump’s tweets, as well as a White House statement confirming that all of Trump’s tweets are considered to be official statements by the president.
