Rep. Devin Nunes, the top Republican on the House Intelligence Committee, said Thursday that certain evidence obtained by special counsel Robert Mueller would be thrown out if ever taken to court.

During an interview on Fox News, Nunes was asked about recent leaks of Justice Department official Bruce Ohr's testimony last year before Congress.

Ohr told investigators that he acted as a back channel between certain FBI officials and Christopher Steele, the author of the Trump dossier. He also said he believes he not only briefed senior Justice Department personnel, including lawyer Zainab Ahmad and fraud unit head Andrew Weissmann who now work for Mueller, but also informed them that the information he took from Steele was likely biased and unproven.

Steele's dossier, which contains unverified claims about Trump's ties to Russia, was then used by the FBI to obtain the authority to spy on a Trump campaign official who had suspicious ties to Russia.

"You have two people that are currently on the special counsel that were in the chain," Nunes said. "They were taking evidence that now they're using."

Nunes, who while chairman of the House Intelligence Committee led its Russia investigation, noted that DOJ and FBI officials told the panel that they didn't know about the dossier until right before a surveillance warrant was obtained for onetime Trump campaign official Carter Page, but recent revelations show officials knew long before.

Asked to confirm if Mueller's team were to bring "any of this" to court, with officials having not revealed any conflicts, Nunes said "yes," the evidence would be thrown out in a court of law.

Zainab Ahmad serves as a lawyer on Mueller's team, while Andrew Weissmann is one of the special counsel's top prosecutors.

Ohr said he also spoke with two former members of Mueller's team: ex-FBI lawyer Lisa Page and former FBI agent Peter Strzok, both of whom were kicked out after it was revealed they exchanged text messages, amid an affair, with a clear bias against President Trump.

Ohr, formerly the associate deputy attorney general and director of the Organized Crime Drug Enforcement Task Force, was demoted after it came to light he met with Steele and Fusion GPS co-founder Glenn Simpson. His wife, Nellie Ohr, had done Russia research work for Fusion GPS and also passed along a thumb drive to her husband to give to the FBI.
