Deputy attorney General Rod Rosenstein announced the indictments of 13 foreign individuals and three entities in the special counsel probe.
A federal court handed up indictments against 13 Russian individuals and three Russian entities in special counsel Robert Mueller's probe of Trump campaign ties to Russia.
The Russian nationals are "accused of violating U.S. criminal laws in order to interfere with U.S. elections and political processes."
President Donald Trump has disputed the widely shared view of U.S. law enforcement and intelligence services that Russia interfered in the 2016 presidential election.
The Russians named in the indictment are accused of posing as Americans on social media to influence American political discourse in an operation that started as early as 2014.
The indictment notes that the defendants were by mid-2016 "supporting the campaign of Donald Trump and disparaging Hillary Clinton," sometimes posing as Bernie Sanders or Jill Stein supporters.
Court documents also list the names of Russians involved and extensively lists their efforts, as well as identifying many of the social media advertisement campaigns conducted by the Russians.
The indictment also shows the Russians posed as Americans to communicate with "unwitting individuals associated with the Trump Campaign" and other activists to coordinate their activities, including political rallies.
