That's the exact title of CTH's post: Roger Stone Questions DOJ on Predicate of Russia DNC Hack. This is, IMO, an important development. There are many--including acknowledged experts in the field such as William Binney--who have challenged the entire "Russian hacking" narrative. That narrative--bolstered by the tendentious and misleading (at best) IC "assessment" and by repeated hacking hoaxes falsely attributed to Russia--is finally being challenged in court. Here's the Wikipedia summary of Binney's position:
Binney claims the U.S. intelligence community's assessment that Russia interfered in the 2016 presidential election is false, and that the Democratic National Committee e-mails were leaked by an insider instead.[23][24][25] He has appeared on Fox News at least ten times between September 2016 and November 2017 to promote this theory.[18][23][24] Binney said that the "intelligence community wasn't being honest here".[23] He has also been frequently cited on Breitbart News.[18] In November 2017 it was reported that a month earlier, Binney had met with CIA Director Mike Pompeo at the behest of President Trump.[23]
Stone's motion to suppress contains two attachments that provide technical support for his position. The first is a Declaration by Binney that provides his background and expertise hand his opinions and conclusions regarding the purported hack of the DNC server. The second attachment is the statement of another acknowledged expert who presents his analysis and conclusions, which agree with those of Binney.
