Two primary sources cited in Nunes memo question its credibility

Two of the primary sources cited in the controversial memo crafted by Congressman Devin Nunes (R-CA) explained on MSNBC's "The Beat" that the manner in which their work was cited caused them further distrust.

"I was as surprised as anybody to see my story cited in the memo as having been extensively cited to the FISA court," Yahoo News chief investigative reporter Michael Isikoff admitted.

"Everything in the story that I broke in Yahoo News in September of 2016 was information that was already known to the FBI," Isikoff noted. "So it is a little baffling as to why they would have needed to cite my story to the FISA court."

"I have to say it's a rather dubious honor to be part of a stunt this way," said David Corn, the Washington bureau chief for Mother Jones.

"Like my friend and co-author, Mike, I was surprised to see me in there because they're just citing public information," Corn continued.

Isikoff and Corn are the co-authors of the upcoming book Russian Roulette: The Inside Story of Putin's War on America and the Election of Donald Trump.

"When you look at one thing I know well here and I see them exaggerate it, it makes me wonder about everything else," Corn noted. "It's an impossible document to work with if you're trying to get to the truth of any of this."

"He is saying that his primary interaction with the same set of facts makes him come to the collusion that this is not a straight telling, it's exaggerated in places. What is your view?" Melber asked Isikoff.

"That is patently obvious. It is clearly a sketchy account of what went into that FISA application," Isikoff replied.
