WATCH: Trump Reveals New Nickname for Hillary

Donald Trump went after Hillary Clinton's maiden name on Monday, unveiling a new nickname for his presidential opponent: "Hillary Rotten Clinton."

"Why did Hillary get rid of her middle name, huh?" Trump asked during a town hall in Roanoke, Va., repeating "rotten" several more times instead of "Rodham."

"Hillary Rotten Clinton, right? Maybe that's why: It's too close," Trump said.
