Rep. Matt Gaetz (R-Fla.) tore into special counsel Robert Mueller, saying Mueller would have to get credentials for the mainstream media if he were any more biased.

"It's just outrageous to see this biased Mueller probe continue," Gaetz, a frequent critic of Mueller, said during an interview on Fox News on Tuesday.

"If Bob Mueller were any more biased, we'd have to give him credentials for the mainstream media."

He noted during the interview he has been calling for Mueller to be fired for months.

"We've got an attorney general who's a spectator rather than the leader of the Department of Justice and that undermines our democracy," Gaetz said during the interview.

"There's no legal requirement for him to have recused himself in this matter. He needs to step up, be the attorney general, fire Mueller and appoint a second special counsel to evaluate the Clinton Foundation."

Earlier this month, Gaetz said he spoke with President Trump Donald John TrumpSteele Dossier sub-source was subject of FBI counterintelligence probe Pelosi slams Trump executive order on pre-existing conditions: It 'isn't worth the paper it's signed on' Trump 'no longer angry' at Romney because of Supreme Court stance MORE personally to tell him that Mueller's probe was "infected with bias" against Trump, according to Politico.

A few other Republicans who have been critical of Mueller's probe have also indicated they previously communicated with the White House about the Russia investigation.

Mueller, a former FBI director, is investigating Russian interference in the 2016 presidential race and whether the Trump campaign colluded with Moscow.

President Trump has repeatedly referred to the Russia probe as a "witch hunt" has denied collusion between his campaign and Russia.

Trump this past week took to Twitter to step up his attacks on FBI officials.
