In response, Dotcom tweeted "Let me assure you, the DNC hack wasn't even a hack. It was an insider with a memory stick. I know this because I know who did it and why," adding "Special Counsel Mueller is not interested in my evidence. My lawyers wrote to him twice. He never replied. 360 pounds!" alluding of course to Trump's "400 pound genius" comment.
Dotcom's assertion is backed up by an analysis done last year by a researcher who goes by the name Forensicator, who determined that the DNC files were copied at 22.6 MB/s - a speed virtually impossible to achieve from halfway around the world, much less over a local network - yet a speed typical of file transfers to a memory stick.
