(CNN) -- The Trump administration is unleashing additional sanctions against seven Russian oligarchs with ties to President Vladimir Putin along with 12 companies they own or control. The measures announced by the Treasury Department on Friday were also aimed at 17 senior Russian government officials and the state-owned Russian weapons trading company, Rosoboronexport, which has long-standing ties to Syria and its subsidiary, Russian Financial Corporation Bank. "Russian oligarchs and elites who profit from this corrupt system will no longer be insulated from the consequences of their government's destabilizing activities," Treasury Secretary Steven Mnuchin said in a statement, citing Russia's occupation in Crimea and its ongoing efforts to supply the Assad regime in Syria with materials and weapons.
