Donald Trump said Saturday that the reopening of an investigation into Hillary Clinton was the result of a "revolt" at the FBI for not pursuing Clinton earlier.

"I'll bet you, without any knowledge, there was a revolt in the FBI," Trump said while in Colorado on Saturday. "I'll bet you there was a revolt in the FBI by what they allowed to happen with respect to Hillary Clinton."

The FBI reopened its investigation on Friday into Clinton's use of a private email server to handle classified emails while serving as Secretary of State. It said it found over 1,000 new emails from a separate investigation that required it to reopen the case. The FBI had closed the investigation earlier this year after finding little evidence of major criminal malfeasance.

"The whole thing should have been over with a year ago," Trump said. "She is so guilty."

"Now the evidence is so overwhelming," he said, "because they wouldn't have done this if it wasn't overwhelming."

"Despite that the attorney general [Loretta Lynch] didn't want anything to happen to Hillary,"he added. "It's very sad."

"You have amazing people in the Department of Justice and you have amazing people in the FBI," he said. "These are great men and women." But "it deadens and saps the spirit of civic participation when you see what has gone on," he added.

"Corruption decays out trust in institutions and our legal system itself," Trump said. "When the outcome is fixed when the system is rigged people lose hope, not only in the system but in our country itself."
