"We have a serious problem, and it's a temporary ban -- it hasn't been called for yet, nobody's done it, this is just a suggestion until we find out what's going on," the presumptive Republican presidential nominee told Fox News Radio's Brian Kilmeade.
Trump first introduced the proposed ban back in December and he explicitly and authoritatively said in both a speech and in a press statement: "Donald J. Trump is calling for a total and complete shutdown of Muslims entering the United States until our country's representatives can figure out what is going on."
