The U.S. law firm representing a Russian business charged in a special counsel's case in Washington should not be permitted to share sensitive information with the company's officers and employees outside the United States, federal prosecutors told a judge Wednesday.

In a new court filing, prosecutors revealed that nonsensitive discovery materials provided to Reed Smith, the U.S. law firm representing the Russian company Concord Management and Consulting, had been altered and disseminated online in October as part of an apparent effort to discredit the investigation into Russian interference in the 2016 election.

The documents were posted publicly from the Twitter account @HackingRedstone, which claimed to have retrieved the papers by hacking into a Russian server. The Twitter account, as of Wednesday afternoon, was “suspended” and not publicly viewable.

Concord's lawyers at Reed Smith have quarreled for weeks with special counsel prosecutors over who can have access to information being produced in the case. The Reed Smith team, led by partners Eric Dubelier and Katherine Seikaly, said in December that prosecutors had produced nearly 4 million documents, and designated 3.2 million of them as “sensitive.”

Dubelier and Seikaly were not immediately reached for comment Wednesday. Prosecutors did not accuse either lawyer, or their law firm, of leaking or otherwise facilitating any unauthorized release of discovery material. Reed Smith said in a statement Wednesday:

“Reed Smith and its lawyers have at all times complied with the protective order in this case. As such, no data was obtained via a breach of Reed Smith systems and we are confident that Reed Smith systems have not been breached. We maintain the highest levels of security and protection for all of our systems and their contents.”

Prosecutors said the public dissemination of nonsensitive discovery illustrated why sensitive materials should not be shared with Concord's officers in Russia.

“Concord's request to send the sensitive discovery to the Russian Federation unreasonably risks the national security interests of the United States,” prosecutors wrote. They added: “Nothing has occurred during the pendency of this litigation to ameliorate these risks. On the contrary, the government's concerns are only heightened by the apparent release and manipulation of information produced to Concord as 'non-sensitive' discovery in this case.”

The government said some of the material online matched certain nonpublic case file markers, and that “the file names and structure of the material produced by the government in discovery are not a matter of public record.”

“The FBI's ongoing review has found no evidence that U.S. government servers, including servers used by the Special Counsel's Office, fell victim to any computer intrusion involving the discovery files,” prosecutors said in their court filing.

Reed Smith said in its statement that the firm has “never hosted or maintained any of the data at issue here produced by the government in the Concord case on Reed Smith computer systems. A third party vendor has hosted all such data and has assured us that there has been no breach of the database that maintains the data.”

Concord Management and Consulting was among the 16 Russian entities and individuals charged in Washington's federal trial court with participating in a scheme to sow discord in the U.S. electorate in 2016. No other law firm other than Reed Smith has entered an appearance for any of the defendants.

“In this first-of-its-kind prosecution of a make-believe crime, the Office of Special Counsel maintains that it can unilaterally—and for secret reasons disclosed only to the court— categorize millions of pages of non-classified documents as 'sensitive,' and prohibit defense counsel from sharing this information with defendant Concord for purposes of preparing for trial,” Dubelier wrote in a court filing in December.

The defense lawyers added: “The position of the court and the Special Counsel creates an insuperable obstacle to defense counsel preparing for trial.”

Featuring prominently in the prosecutors' filing Wednesday was Yevgeny Prigozhin, a Russian oligarch whose restaurants and catering businesses have hosted dinners attended by Vladimir Putin, earning him the nickname “Putin's chef.” As an officer of Concord, Prigozhin was among the Russians charged last year with conspiring to interfere in the 2016 election.

In late June, U.S. District Judge Dabney Friedrich set restrictions on discovery the government deemed sensitive, preventing Reed Smith from sharing such materials without her permission. Friedrich also ordered Reed Smith to store sensitive materials in a locked room at its U.S. offices “when they are not in the actual possession of defense counsel.”

On Wednesday, prosecutors said Prigozhin could potentially view sensitive materials if he traveled to the United States.

“To the extent that Concord faces challenges in mounting its defense, it is because Prigozhin refuses to come to the United States to review the sensitive discovery,” prosecutors wrote. “That is a problem of Concord's own making.”
