"Hillary Clinton is a weak person. Hillary Clinton is totally scripted. Hillary Clinton is a thief. And Hillary Clinton should be in jail for what she did to our national security," the presumptive GOP presidential nominee said at the event in Redding, Calif.

“If you choose Hillary Clinton, this country is going to die.”

Responding to Clinton's assertion that he is unqualified to be president, Trump hit her with a similar insult.

"I think that Hillary Clinton is unfit to lead our country, certainly at this time,” he said. "I call her 'Obama light'; I think it's going to be as bad or maybe worse."

Trump ripped Clinton for using a teleprompter in her Thursday speech.

"I don't have teleprompters; I don't need teleprompters. It's called up here, it's called memory, it's called other things," he said, pointing to his head.

"A lot of people didn't know that — she was reading a script. She'd read a line, and then she had the phony audience," Trump said, accusing her of having a staffer prod the audience to clap.

"If I ever did that, I'd be run out of town, but for Hillary, it's ok," he said.

Trump also criticized Clinton for using a private email server while she was secretary of State, promising that the Justice Department would look into charging her with a crime under his administration.

"Everything will be fair, but we will have an attorney general, and the attorney general is going to take a look," he said.
