“Chairman Nunes’ recusal is critical in order to preserve the integrity and independence of the U.S. House of Representatives,” they wrote in a Tuesday letter to Ryan.

“Congress must come together in a bipartisan fashion to understand the nature of this attack and the scope of Russian ties to [President Trump’s 2016] campaign, transition team and presidential administration,” they added.

“This is about country, not party. Chairman Nunes has demonstrated his bias, and the public will no longer accept the results of this probe as legitimate under his leadership.”

Nunes has faced bipartisan criticism over his actions while the House Intelligence panel probes Russian meddling in the 2016 presidential race.

Nunes, who was involved in Trump's transition, created an uproar last month by publicly revealing he had seen evidence members of the transition team were incidentally surveilled during a broader intelligence probe.

The California lawmaker visited the White House one day before making the revelations, sparking concerns about where he got the information, which was not immediately shared with fellow committee members.

Reports emerged last week that two White House officials helped Nunes acquire the information he made to claim Trump’s transition was swept up in foreign surveillance.

National Security Council member Ezra Cohen-Watnick and Michael Ellis, a national security lawyer with the White House Counsel’s Office, are purportedly the two individuals who aided Nunes.

Nunes quickly briefed Trump on the reports after speaking with the press, drawing ire from Democrats on the panel.

Critics worry Nunes’s decisions have cast doubt on his panel’s ability to remain impartial while scrutinizing Russian’s election interference last year.

Many Democrats have called for Ryan to remove Nunes from the chairmanship. Ryan has so far stood by his colleague.
