If the President intended to bar all Muslims from entering the U.S., he would have (and easily could have) restricted travel from all 57 Islamic countries.
He didn’t do that, though, did he?
Trump’s original stance had nothing to do with specific countries whether they be 7 or 57. His original statement was
“a total and complete shutdown of Muslims entering the United States until our country’s representatives can figure out what is going on,” a campaign press release said.”
