Patten, 47, pleaded guilty in August to communicating with U.S. lawmakers and news media organizations on behalf of a Russia-aligned political party in Ukraine called the Opposition Bloc without disclosing that work to the Justice Department, in violation of the Foreign Agents Registration Act (FARA), among other offenses.
Patten is a former business partner of Konstantin Kilimnik, a Russian national indicted by Mueller and accused of having ties to Russian intelligence.
