Special Counsel Robert Mueller has just handed down a set of indictments, charging 13 Russian citizens and three Russian organizations with interference in the U.S. presidential election in efforts dating back to 2014.

The indictment names the Internet Research Agency, a bot farm and disinformation operation based out of St. Petersburg as one of the sources of the fake accounts meant to create divisions in American society. Those accounts were active on Facebook, Twitter and Instagram and the indictment brings up specific examples from the internal review results that these tech companies handed over to Congress.
