Special prosecutors are always on a "witch hunt," says Sen. Rand Paul (R-Ky.). Except maybe when they're investigating Bill Clinton.

Paul jumped on the Robert Mueller-condemning bandwagon on Fox News on Tuesday morning, responding to reports that the FBI raided the office of President Trump's personal attorney Michael Cohen on Monday. Paul explained how even if Mueller doesn't use information obtained in the raid that is protected by attorney-client privilege, he'll still read it. From there, he could get ideas on where to look for details he actually could use in the ongoing Russia investigation, Paul said.

That's why, Paul said, he has opposed special investigations even for officials who blatantly abused their office — a fact he seemed proud of until the skeptical anchor interrupted.

"So how'd you feel about Ken Starr in the '90s?" Fox News' Bill Hemmer asked, referring to the independent counsel who investigated then-President Bill Clinton.

"You know, I may or may not have been as consistent back then, to tell you the truth," Paul responded, with a nervous laugh. "But I've come to believe that now these special prosecutors have too much power."
