Tom Fitton said the FBI reportedly investigating whether President Trump was working on behalf of Russia shortly after he fired former director James Comey shows how "out of control" the bureau is.

"They think that taking action against the FBI director is the same as treason," Fitton, president of Judicial Watch, said on "Fox & Friends First" on Monday. "This is what the deep state is -- 'you oppose the bureaucracy, we're going to target you with an illicit investigation.'"

He added that the FBI had already been "targeting" Trump for some time, pointing to the infamous anti-Trump dossier, which was used by the FBI to launch the initial Trump-Russia investigation and secure surveillance warrants to spy on Trump campaign associates.

"This is an FBI -- at the leadership level at least -- which was rogue," Fitton said, wondering why the FBI's current director, Christopher Wray, has been so silent about his predecessor's "misconduct" and why anti-Trump FBI agents like Peter Strzok were involved in the Russia probe.

He said this all goes to show that many FBI officials were focused on "getting Trump," and he called for an inquiry into possible abuses of power.

"You can't just go after someone because you don't like their politics. That's an abuse of law subject to criminal investigation," Fitton said.
