Muller's investigation into Stone centered around Stone's contacts with Wikileaks, which he said in testimony before Congress that he had communicated with through intermediaries.

The filing repeatedly referred to Stone's contact with "Organization 1," which is believed to be WikiLeaks, which had "posted documents stolen by others" from the US government and citizens.

The filing said that Stone "released tens of thousands of documents stolen from" people including the Democratic National Committee and the personal email account of Clinton campaign chairman, John Podesta.

It also said that Stone deliberately obstructed investigations by the FBI, House Intelligence Committee, and Senate Intelligence Committee into Russian interference in the 2016 election.
