If FBI Director James Comey had held that position in 1973, the Watergate scandal never would have come to light because Comey would have covered it up, former House Speaker Newt Gingrich said Wednesday.

"You're seeing the first clear, visible corruption at the FBI," Gingrich said on "The Mike Gallagher Show."

"And Comey is the agent, and it's sad. It's going to destroy his career."

Comey testified before Congress on Wednesday his agency found no evidence an IT technician was ordered by Clinton or any of her aides to delete emails from her private server. He has previously said the FBI found no evidence to support an indictment of the former secretary of state and current Democratic presidential nominee.

Gingrich said Comey's stance shows what a Clinton presidency would look like.

"It will be the most corrupt administration in American history, which I find frightening," he said. "Having a commander-in-chief that's that corrupt could dramatically weaken the fabric of American society."

The break-in of DNC headquarters in the Watergate Hotel by members of the Committee for the Re-Election of the President brought about the downfall of President Richard Nixon.
