In a speech at the University of North Carolina, Trump suggested gun owners could take Clinton out in order to prevent her appointing judges to the Supreme Court.

"If she gets to pick her judges," Trump said, "nothing you can do, folks. Although the Second Amendment people, maybe there is."

Trump also argued that he is being held to a different standard than Clinton, saying that "it would be a whole different ball game" if he used the same excuses she did.

"She said the other day, she short-circuited," he said, according to a transcript of his remarks. "Could you imagine if I said that I short-circuited? They would be calling for my execution. Electric chair, they'd bring back the electric chair."

Clinton said that she "may have short-circuited" in an interview with Chris Wallace on "Fox News Sunday" when she said that FBI Director James Comey had called her answers about her email use "truthful."

Trump went on to call Clinton "wacky," questioning her judgement and ability to lead the nation.

"It's one thing to make bad decisions," he said. "It's another thing to be wacky and make bad decisions."
