Former Trump campaign chairman Paul Manafort filed on Tuesday as a foreign agent for his firm’s work for a Ukrainian political party. Manafort’s filing to the Justice Department under the Foreign Agents Registration Act showed that his firm made $17.1 million over a two-year period from the Ukrainian political party. Special Counsel Robert Mueller has reportedly been investigating Manafort’s ties as part of the federal probe into alleged Russian meddling in the 2016 election.
