Donald Trump on Saturday sought to attach to Hillary Clinton one of the concerns that some have about him, portraying her as a mentally unstable person who is unfit for the presidency.

"She took a little short-circuit in the brain. She's got problems," Trump said, zeroing in on Clinton's comment last week that she had "short-circuited" an answer related to her honesty in discussing her email server.

"Honestly, I don't think she's all there," said Trump, who spoke during an evening rally in Windham, N.H. "I think the people of this country don't want somebody who's going to short-circuit up here."
