Veteran Intelligence Professionals for Sanity disproved the "hacking" allegations long ago: "Some members of the Veterans’ Intelligence Professionals for Sanity argue that metadata evidence points to a local download from the Democratic computers, in other words a leak, rather than a hack. They write the NSA would have evidence of a hack and, unlike this indictment, could make the evidence public: “Given NSA’s extensive trace capability, we conclude that DNC and HRC servers alleged to have been hacked were, in fact, not hacked. The evidence that should be there is absent; otherwise, it would surely be brought forward, since this could be done without any danger to sources and methods.”
That argument was either ignored or dismissed by Mueller’s team."
