Donald Trump turned his guns back on Hillary Clinton today, asking why she stopped using her “middle name.”

“Why did Hillary get rid of her middle name?” Trump asked a crowd in Roanoke, Virginia.

“No, but why did she get rid of it,” he said as the audience shouted out answers.

“Hillary Rotten Clinton,” he said, repeating, “Rotten Clinton.”

“Maybe that’s why,” he added, “it’s too close,” referring to her maiden name, Rodham.
