Republican presidential candidate Donald Trump is hitting Pope Francis over his upcoming visit to the U.S.-Mexican border.
Trump says in an interview on Fox Business News Thursday, "that the pope is a very political person."
He says, "I think he doesn't understand the problems our country has."
Trump has made securing the border a cornerstone of his campaign, promising to build a wall along the length of southern border and immediately deport all of the estimated 11 million people living in the country illegally.
Trump says of the pope: "I don't think he understands the danger of the open border that we have with Mexico."
