It is basic from looking at the timing and events. HRC devices were hacked by Russian (probably Chinese) malware when she was overseas and then brought it home to her server. She then spread that to DNC server as the FBI agent Hawkins noted it phoning home. DNC had to bring in all devices to scrub them and did not allow FBI access (Awan and DWS really outed to insiders of Dem party at that point). Sometime in here Seth mad at the Bernie cheat downloaded files. Then DNC and HRC used the projection technique and intelligence agencies to push all that on Trump. Not too long after first action was pinging Trump Tower
