Rep. Devin Nunes, the top Republican on the House Permanent Select Committee on Intelligence, charged Friday that special counsel Robert Mueller is the real source of collusion that people should be focused on.

In a Fox News interview, Nunes said Mueller's team essentially colluded with Democrats to bring down President Trump, by accepting the Democrat-generated Steele dossier as evidence against Trump, and using it to further their investigation.

"These guys were meeting with the Democrats, they were taking in this Steele dossier, which was the dirt," said Nunes, R-Calif.

"So these guys were involved in this the whole time," he added. "They're part of it. The Mueller team is part of the collusion."

Nunes said related evidence was seen this week, when former Trump lawyer Michael Cohen met with House Intelligence Committee Chairman Adam Schiff, D-Calif., before Cohen's public testimony before Congress. Nunes said that meeting was likely an effort on how to coach the witness.

"They met with Cohen, they clearly were trying to devise how they're going to roll out a new narrative. So the last two weeks was all about rolling out a new narrative," Nunes said.

"No matter how much witness tampering you do, you're not going to find collusion in this, unless you talk about the collusion that the Democratic Party and the Clinton campaign were doing with Russians," he added.
