ALERT -- US Congressman Claims '10 ISIS Fighters' Have Been Caught Crossing Into US!

A Republican congressman claimed Tuesday that "at least 10" Islamic State "fighters" have been caught trying to cross the U.S.-Mexico border into Texas, though an administration official denied it. Rep. Duncan Hunter, R-Calif., said he learned the information from the Border Patrol, warning that the alleged attempts to cross into the U.S. raise serious security concerns. "ISIS is coming across the southern border," he told Fox News. "They aren't flying B1 bombers bombing American cities, but they are going to be bombing American cities coming across from Mexico."
