And how do you know this, hmm?
Because the DNC said so? No.
Because Russian trojans were found on the DNS server by data forensics? Hell no.
So that's 80% more implausible than my theory.
Because 12 Russian agents have been INDICTED for doing that
US indicts 12 Russians for hacking DNC emails during the 2016 election
Your "theory" is identical to that being pushed by the Kremlin. You must be so proud
"The Russians used techniques including “spearphishing” and spying software, before publishing the emails through well-known online accounts including Guccifer 2.0 and DCLeaks, which purported to be independent American and Romanian hackers. Rosenstein said both personas were in fact operated by the GRU."
Not many people read that Guccifer 2.0 and DCLeaks stuff.
What people read was Wikileaks, and that didn't come from Russian hackers, sorry.
PS: "The Guardian"? Bwahahaha! If you were a rightist, that would be like using InfoWars for a source.
