Rep. Trey Gowdy, R-S.C., suggested in an interview that FBI Deputy Director Andrew McCabe may soon lose his job as scrutiny over the agency intensifies.

McCabe is scheduled to testify Tuesday in front of the House Intelligence Committee on the subject of FBI agent Peter Strzok, who was removed from special counsel Robert Mueller's Russia inquiry team because of text messages that were critical of President Trump during the 2016 campaign.

"I'll be a little bit surprised if he's still an employee of the FBI this time next week," Gowdy, a member of the House Judiciary Committee, said of McCabe in an interview Friday night with Fox News.

Trump and congressional Republicans have accused the FBI of apparent political bias and conflicts of interest after some agents and their associates were revealed to have connections to Democratic politics, including ties to Hillary Clinton.

Republicans charge that the bias has tainted the FBI and Mueller's investigation into possible ties between the Trump campaign and Russia.

Trump in July suggested on Twitter that McCabe should have been fired already.

"Why didn't A.G. Sessions replace Acting FBI Director Andrew McCabe, a Comey friend who was in charge of Clinton investigation but got...big dollars ($700,000) for his wife's political run from Hillary Clinton and her representatives," Trump said at the time. "Drain the Swamp!"
