The dems made up Guccifer 2( the person behind guccifer one is in prison) they called it guccifer 2, to imply it was russian. They had Guccifer 2 publish some of the dnc emails( non important ones) in order tomake it look like the russians hacked them, and was not an inside job with Seth Rich.
They knew Rich probably gave them to wikileaks so they created the fake guccifer 2 as a cover. The y began releasing non important emails 2 weeks after Rich was murdered, under that guccifer 2 guise in order to get ahead of the story and control it.
Guccifer 2 does not exist, nor did they hack anything.
