“No. 1, it is illegal what she did here,” added the GOP’s presumptive presidential nominee. "But it’s also bad judgment.

“I’ve always heard that once an email gets sent out, it never really leaves you. Our enemies likely have a blackmail file on her, which should actually disqualify her from running for office.”

“Is there a single person here who believes if you had done what Hillary Clinton had done that you would not be prosecuted?” he asked before introducing Trump.

“They are once again making the case that there are two Americas,” Gingrich added. "There’s the corrupt Washington of the old order and there’s all the rest of us."

Shortly before the campaign rally, Attorney General Loretta Lynch announced that per the FBI's recommendation, the Department of Justice would not press charges against Clinton.
