DNC was leaked by an insider.
Hillary’s email was almost certainly hacked by Ukraine . . . and by Russia, China, France, Germany, England, Israel, Saudi Arabia, North Korea, and every other country with an intelligence service. Anyone who didn’t hack Hillary deserves to be fired for incompetence.
A DNC hack was set up ( by or from Ukraine) to look like ( or be claimed as) Russian intrusion and this was used to get the FISA process underway and get the FBI to pursue Flynn, Manafort and other Trump associates
Thats the unproven conspiracy theory
The FBI was never given access to the hacked server
The DNC hired Crowdstrike to investigate the hack ( Clinton donors) and that is the basis of the Russian meddling story
What FBI Director and FBI leadership would ever accept this?
Wait, we know
