Fox News legal analyst Gregg Jarrett said Robert Mueller's probe into President Donald Trump is "illegitimate and corrupt."

Jarrett made the remarks citing revelations that FBI Agent Peter Strzok and attorney Andrew Weissmann may have demonstrated bias against Trump.

"Mueller has been using the FBI as a political weapon," he said. "The FBI has become America's secret police."

Jarrett compared the way FBI agents entered Paul Manafort's house while he was in bed to the way the KGB "came for you in the dark of night."

He said people like Strzok were examples of agents engaging in otherwise rogue political activity.

"He's the tip of the iceberg," Jarrett said.
