Deputy Attorney General Rod Rosenstein handed over documents related to the launch of the FBI's investigation into Russian election meddling after Congressman Devin Nunes (R-CA) threatened to hold him in contempt of Congress and begin impeachment proceedings against him.

On Wednesday, Nunes released a memo stating that the requested documents had been turned over to his office.

"After numerous unfulfilled requests for an Electronic Communication (EC) related to the opening of the FBI's Russia counterintelligence probe, Chairman Trey Gowdy and I met this afternoon with Deputy Attorney General Rod Rosenstein. During the meeting, we were finally given access to a version of the EC that contained the information necessary to advance the Committee's ongoing investigation of the Department of Justice and FBI. Although the subpoenas issued by this Committee in August 2017 remain in effect, I'd like to thank Deputy Attorney General Rosenstein for his cooperation today."

Congressman Devin Nunes (R-CA) told Fox News's Laura Ingraham on Tuesday that Congress has grounds to begin impeachment proceedings against Wray and Rosenstein.

Nunes, who co-chairs the House Intelligence Committee, claimed that Wray, along with Deputy Attorney General Rod Rosenstein, withheld key documents related to the FBI's investigation into Russian meddling in the 2016 presidential election.

The investigation also probed whether Russia's actions were tied to President Donald Trump's campaign. Nunes said that Wray and Rosenstein had until Wednesday night to turn over the requested documents, after which things would become "really complicated.

Specifically, Nunes referred to documents that were requested to be submitted as un-redacted. He alleges that Wray and Rosenstein intentionally turned over fully redacted and partially redacted "trickle-down" documents.

The redacted EC (electronic document) contains information that helped spark the FBI probe, and are a key piece of evidence in Nunes' investigation of the Department of Justice and the FBI.

"If the record wasn't that every time they hide something from us, that then we find out it was really bad it was bad it was hidden from us for a long time... like the texts, the FISAs, the warrants against Carter Page... just the fact that they're not giving this to us tells me there's something wrong here."

Ingraham then asked Nunes if he was planning on holding Wray and Rosenstein in contempt of Congress.

"We are going to get the documents. We are going to get the two pages. So they can either cough them up now or it will get really complicated starting tomorrow night and we'll have to get all the steps necessary to get the documents, Nunes said. "We're not just going to hold in contempt, we will have a plan to hold in contempt and to impeach."
