A group of Republican House members are reportedly working behind closed doors to expose “corruption and conspiracy” at the highest levels of the nation’s law enforcement agencies.

The group of GOP members from the House Intelligence Committee are attempting to discredit Special Counsel Robert Mueller’s inquiry into whether the Trump campaign colluded with Russia, according to a report in Politico.

The group is led by Rep. Devin Nunes (R-Ca) and suspects the FBI and Justice Department have both worked to derail the Trump presidency while aiding the candidacy of Hillary Clinton, Politico reported.

A spokesman for Nunes pointed to a Fox News interview from earlier this month in which the congressman criticized the law enforcement agencies and mentioned a probe into their “abuses.”

“I hate to use the word corrupt, but they’ve become at least so dirty that who’s watching the watchmen? Who’s investigating these people? There is no one,” Nunes said on Fox.
