The Daily Beast is reporting Guccifer 2.0 was a Russian Intelligence Officer:
Guccifer 2.0, the “lone hacker” who took credit for providing WikiLeaks with stolen emails from the Democratic National Committee, was in fact an officer of Russia’s military intelligence directorate (GRU), The Daily Beast has learned. It’s an attribution that resulted from a fleeting but critical slip-up in GRU tradecraft.
Mueller is involved:
The Daily Beast has learned that the special counsel in that investigation, Robert Mueller, has taken over the probe into Guccifer and brought the FBI agents who worked to track the persona onto his team.
Is Roger Stone’s time up?
Last May, Stone admitted that he’d also exchanged direct messages with the Guccifer 2.0 persona, and he released what he claimed was a complete transcript of his communications with the account. The transcript is brief and banal, showing Stone congratulating Guccifer 2.0 on returning to Twitter after a brief suspension, and then mostly ignoring him. Then and since, Stone has consistently denied that Guccifer was connected to the Kremlin.
