CLEVELAND — Rudy Giuliani says the criminal case against Hillary Clinton in the e-mail scandal would be revived if Republicans take back the White House — and he’d like to be the one to prosecute her.

Speaking to a fired-up New York delegation at the GOP convention on Thursday, the former mayor ignited cheers of “Lock her up!” when he said Clinton was beating the judicial system.

“We can’t do anything about that yet,” Giuliani said. “If Donald Trump becomes president, the statute of limitations is not up. There is no double jeopardy . . . We can reopen the case.”

“Go get ’em!” shouted one Republican at the Cleveland Marriott Renaissance Hotel, sparking cheers.

“She’s going to be running to try to prevent getting an orange jumpsuit,” Giuliani said.

The Justice Department has declined to prosecute Clinton for mishandling classified material on her private e-mail server while secretary of state.

But many GOP delegates believe she belongs in prison.

Giuliani told his fellow Republicans he’s “really sick with what the Clintons have been allowed to get away with.”

He then addressed Joseph Mondello, former chair of the New York state GOP and an attorney.

“Joe, what do you think we go back one more time when Trump gets elected, we volunteer to try the case?”

“Yeah,” Mondello replied.

“Dan, you want to help us?” Giuliani yelled to Rep. Dan Donovan, the former Staten Island district attorney.

“I’m in,” said Donovan, who told The Post he expects a new attorney general under Trump would give the Clinton case “a fresh look.”

“A Trump attorney general could reopen the investigation into Benghazi, reopen the investigation into the e-mails, look at whether or not she perjured herself during her testimony to Congress and also look into the non-for-profit organization, the [Clinton] Foundation, where there’s a clear conflict of interest,” Donovan said.
