(CNN) — WINDHAM, New Hampshire Donald Trump pumped up his attacks on Hillary Clinton’s character Saturday night by suggesting that the former secretary of state is not mentally fit to be president.

“She took a short-circuit in the brain. She’s got problems,” Trump said, seizing on Clinton’s explanation that she “short-circuited” a recent answer about her truthfulness in discussing her email server.

“Honestly, I don’t think she’s all there,” he added.
