The endgame:
In documents submitted to the U.S. district court, the special counsel’s office detailed some of the evidence against Roger Stone, acknowledging for the first time they possess direct communications between Stone and Russian operatives known collectively as Guccifer 2.0, as well as WikiLeaks.
The communications were gathered in connection to an indictment that Robert Mueller brought against 12 Russian intelligence operatives last year. Those individuals, who were all members of Russia’s Main Intelligence Directorate, or GRU, operated under aliases including DCLeaks and Guccifer 2.0.
…In its initial indictment against Stone last month, the special counsel’s office revealed that a senior Trump campaign official “was directed” to reach out to Stone regarding WikiLeaks’ publication of John Podesta’s emails. Now that Stone himself was shown to have been in direct communication with Russian intelligence operatives, there is a direct line running between the Trump campaign and Russian military intelligence officials.
