Special counsel Robert Mueller has communications between longtime Trump associate Roger Stone and WikiLeaks, according to a new court filing from prosecutors.

In the course of investigating the Russian hack of Democratic Party emails, "the government obtained and executed dozens of search warrants on various accounts used to facilitate the transfer of stolen documents for release, as well as to discuss the timing and promotion of their release," prosecutors wrote Friday to a federal judge.

"Several of those search warrants were executed on accounts that contained Stone's communications with Guccifer 2.0 and with Organization 1,” they said, referring to WikiLeaks as Organization 1.

Stone was charged in January with lying to Congress, witness tampering, and obstructing the special counsel’s investigation into Russian interference in the 2016 election. The 66-year-old pleaded not guilty to all charges.

Prosecutors said at the time that Stone lied about his communications with WikiLeaks and senior Trump campaign officials and that their evidence of wrongdoing was “ both voluminous and complex.”

It’s unclear if the communications Mueller has between Stone and WikiLeaks goes beyond those that were reported by the Atlantic and the Daily Caller in February 2018.

A judge also issued a gag order in the case against Stone on Friday, forbidding attorneys for both Mueller and Stone from “making statements to the media or in public settings that pose a substantial likelihood of material prejudice to this case.” Stone is also not allowed to speak about the case in or around the courthouse.
