A major focus of the probe has been whether Stone coordinated with WikiLeaks or its founder, Julian Assange, as the group published thousands of Democratic emails that prosecutors say were hacked by Russian operatives.
Stone was not charged with any crimes related to communicating with WikiLeaks about its activities, and he has repeatedly denied that he conspired with the group.
But his 24-page indictment details numerous occasions when Stone claimed to campaign officials that he had information about WikiLeaks or was in contact with Assange — and it depicts Trump aides and allies as acutely interested in learning about the group’s plans in advance.
Among those who sought information from Stone, according to the filing, was a “senior Trump Campaign official” who “was directed” by an unnamed person to contact Stone as soon as WikiLeaks began publishing Democratic emails in the summer of 2016.
Stone also communicated about WikiLeaks with “a high ranking Trump Campaign official,” whose emails in the filing match those of former campaign chairman Stephen K. Bannon. And Stone received a query about the group’s activities from a “supporter involved with the Trump campaign,” whom he then asked to communicate via a secure messaging app, according to prosecutors.
