Devin Nunes makes serious request after glaring discrepancy found in Mueller source docs

Rep. Devin Nunes (R-Calif.), the top Republican on the House Intelligence Committee, is calling for the public release of "all backup and source documentation" related to Robert Mueller's Russia investigation after a discrepancy surfaced in source documents provided by the special counsel's office.

What are the details?

Nunes' reaction came after the public release of a Nov. 2017 voicemail transcript from former Trump lawyer John Dowd to the attorney representing former national security adviser Michael Flynn in which Dowd asked Flynn's attorney for a "heads up" if Flynn knew material damaging to the president.

The transcript released Friday included new content that was not included in Mueller's source documentation.

"It's all a fraud," Nunes said.

Side-by-side comparison shows documentation provided by Mueller left out crucial contextual details, including where Dowd explicitly said he was not asking for "any confidential information" and when Dowd said his request was "not only for the president but for the country."

Here's the complete Dowd transcript:

Hey, Rob, uhm, this is John again. Uh, maybe, I-I-I'm-I'm sympathetic; I understand your situation, but let me see if I can't ... state it in ... starker terms. If you have ... and it wouldn't surprise me if you've gone on to make a deal with, and, uh, work with the government, uh ... I understand that you can't join the joint defense; so that's one thing. If, on the other hand, we have, there's information that. .. implicates the President, then we've got a national security issue, or maybe a national security issue, I don't know ... some issue, we got to-we got to deal with, not only for the President, but for the country. So ... uh ... you know, then-then, you know, we need some kind of heads up. Um, just for the sake of ... protecting all our interests, if we can, without you having to give up any ... confidential information. So, uhm, and if it's the former, then, you know, remember what we've always said about the President and his feelings toward Flynn and, that still remains, but-Well, in any event, uhm, let me know, and, uh, I appreciate your listening and taking the time. Thanks, Pal.

Flynn, who plead guilty to lying to federal investigators in Dec. 2017, claims the call is evidence of an effort to obstruct Mueller's investigation, according to Fox News.

Dowd, however, vehemently disagrees, calling the voicemail transcript a "baseless, political document designed to smear and damage the reputation of counsel and innocent people."
