Devin Nunes: Congress has seen no ‘credible evidence’ justifying the Russia investigation

House Intelligence Committee Chairman Devin Nunes said Monday that Congress has yet to see any solid rationale for the Justice Department’s decision to launch the Russia investigation against President Trump, and said he’s hoping to see more when he meets with officials Wednesday.

“We have yet to see any credible evidence or intelligence that led to the opening of this investigation,” the California Republican said on Fox News.

Nunes has been pushing the Justice Department to explain how it justified the launch of the special counsel investigation that has hounded Trump for a year now. He and House Oversight and Government Reform Committee Chairman Trey Gowdy, R-S.C., are keying off a statement from Fusion GPS’ Glenn Simpson, who said a source within the Trump campaign provided information for the controversial Trump dossier.

Nunes said if there was a “spy” of some sorts in Trump’s campaign, that could look bad for the Justice Department, since it could give the appearance that they were trying to set up Trump for a fall.

“I think what it really means, I think it will look badly on the Department of Justice and the FBI on how they conducted this investigation,” he said.

Nunes said he believes that Simpson was telling the truth about a source within the campaign, which is why they are pushing the Justice Department to explain what it knows.

“We believe he was telling the truth, and what we’re trying to do is get the documents to figure out did they actually have… what methods were used to open this counterintelligence investigation,” he said.

He also said the department never should have opened a counterintelligence investigation into Trump, which is a step that isn’t normally taken against a political campaign.

“I believe they never should have opened a counterintelligence investigation into a political party,” he said.
