The piles of papers, which show details from grand jury subpoenas sent to 15 people, and movements likely including opposition research firm Fusion GPS, was produced this month after lawyers representing Sussmann. Sussmann denies any wrongdoing and demanded more information while calling the allegations that he lied to the FBI five years ago 'vague and confusing'.
A grand jury returned an indictment last month that focuses on a September 2016 meeting between Sussmann and then-FBI General Counsel James Baker in which the lawyer passed along information about concerns of covert communications between Russia's Alfa Bank and the business of former President Donald Trump, who was the Republican presidential candidate at the time.

Although Durham claimed Sussmann told Baker he was not going for any specific client, the special counsel asserts Sussmann was secretly doing the bidding of former Secretary of State Hillary Clinton's presidential campaign while billing her team for it and working on behalf of technology executive Rodney Joffe.

In the court filings Wednesday, Durham said his office gave results of discovery to the defense on Oct. 7, which "included more than 6,000 documents, comprised of approximately 81,000 pages."
Among these reports, the special counsel said, were those "received in response to grand jury subpoenas issued to fifteen separate individuals, entities, and organizations — including among others, political organizations, a university, university researchers, an investigative firm, and numerous companies."

The investigative firm in question is likely Fusion GPS. Durham said his office "has provided the identity of that investigative firm to the defense, even though counsel was undoubtedly already aware of that firm's identity."

Fusion GPS hired British ex-spy Christopher Steele in 2016 to collect his now-discredited anti-Trump dossier. Sussmann, a Perkins Coie law firm partner, met with Steele during the 2016 election and talked with the opposition research firm that year.

Durham's team spoke with Sussmann's lawyers seven times in September and October "to discuss discovery issues, answer counsel's questions, address technical issues, and preview its forthcoming discovery productions," the court filings in the U.S. District Court for the District of Columbia said.

After Sussmann was indicted, his lawyers began to pick apart the case. "The Special Counsel has brought a false statement charge on the basis of a purported oral statement made over five years ago for which there is only a single witness, Mr. Baker; for which there is no recording; and for which there are no contemporaneous notes by anyone who was actually in the meeting," his lawyers said. "Not only that, but the Special Counsel has brought this false statement charge even though Mr. Sussmann has consistently maintained — including in testimony under oath — that he met with Mr. Baker on behalf of a cyber expert client."
