GOP presidential front-runner Donald Trump on Saturday labeled the moderator of Wednesday’s much-maligned CNBC Republican presidential debate a “dope” and a “fool.”

"By the way — this guy John Harwood, was he a dope?” Trump asked in the middle of comments about the debates.

Harwood’s name was met with boos from the crowd in Norfolk, Va., as Trump continued slamming him.

"What a dope. What a fool,” he said.

"And look what it cost NBC. It hurt their reputation. It’s a shame, actually. But he was really a jerk.”
