Donald Trump reacted forcefully today to a statement from Pope Francis which suggested the GOP frontrunner isn't Christian because he wants to build a wall on the U.S.-Mexico border.

"A person who thinks only about building walls, wherever they may be, and not of building bridges, is not Christian," the pontiff said in a statement today.

Trump responded by reading from a written statement, something he very rarely does, to get his point across:

"No leader, especially a religious leader, should have the right to question another man's religion or faith, especially when they feed all sorts of false information into him. They're using the pope as a pawn and they should be ashamed of themselves -- that's the Mexican government -- especially when so many lives are involved and when illegal immigration is so rampant."

As John Roberts was reporting from a North Charleston restaurant on The Real Story, Mr. Trump walked over for an impromptu interview.

Trump said that he sees the pope's comments as an effort by Mexico to take the focus off of other things that are coming into America via the southern border.

"I do respect the pope. It's not really his fault," he said.

Trump noted that in New Hampshire, voters kept asking him about what he could do about the heroin and drug problems there. 

"We have to close up the border," said Trump.
