An alleged Russian troll farm, which has been indicted by Robert Mueller, said in a court filing Thursday that the special counsel has “obtained a nude selfie” as part of his investigation.

The company, Concord Management and Consulting, filed a motion in court that claimed Mueller is unlawfully keeping materials away from it — and casually mentioned the existence of a lewd photo.

It was not clear Thursday where the alleged nude pic came from or who had taken it.

The company’s lawyer, Eric Dubelier, made the striking allegations while criticizing Mueller’s tight hold on information in the sprawling Russia probe.

“Could the manner in which he collected a nude selfie really threaten the national security of the United States?” Dubelier wrote in the memo.

The lawyer argues that the special counsel has restricted the company from viewing sensitive documents and “now seeks to completely obliterate any remaining rights of Concord to defend itself.”

Concord is accused of conspiring against the US by using a massive operation of fake social media personas to wield division and “sow discord” in the country.

The special counsel’s office did not immediately respond to a request for comment.
