Mueller team attorney Jonathan Kravis made the argument Thursday during court proceedings in a case against a Russian company that allegedly gave money to a troll farm accused of spreading misinformation and propaganda during the 2016 election.

He said the 3.2 million documents could be used to find out what information the U.S. government does and does not have and "recreate the steps of the investigation."

"That information, used by a foreign adversary, could be used to avoid detection in the future," Kravis reportedly said.

The company, Concord Management and Consulting, is reportedly run by Russian President Vladimir Putin's associate Yevgeny Prigozhin. It is one of three firms charged in the troll farm case. Thirteen people, including Prigozhin, were also charged.

Mueller's team is investigating whether Russia interfered in the 2016 presidential election. As part of that probe, it is also investigating whether the foreign power colluded with the Trump campaign.
