More than 200 people have been charged in the investigation into “fake news” during the 2016 U.S. election.
The news organization BuzzFeed News first reported the indictment Wednesday.
The Associated Press previously reported that more than 100 of those arrested in the case are believed to be members of Russia’s security service GRU.
The AP also reported that two of the defendants are alleged to have helped organize fake news sites that promoted Trump and other candidates during the campaign.
The indictment says two of those accused in the probe, Alexei Kovalyov and Aleksey Pushkov, worked for a firm called SputnikNews.
Sputnaz was a paramilitary group in the Soviet Union and its members served as agents for the Kremlin.
Sputnik News was founded by former Russian security services agent Sergei Magnitsky in 2009.
He uncovered widespread fraud and abuse of power in the Russian government, and later died in a Russian prison.
In February 2016, Russian investigators opened a criminal investigation into Sputniks for alleged links to the Trump campaign, according to the indictment.
The AP previously reported the investigation was closed in May 2016.
