Former Trump aid Paul Manafort is expected to register as a foreign agent. According to CNN, Manafort and his lobbying firm have been under FBI and Justice Department scrutiny as part of a broader anti-corruption probe. Manafort's consulting firm did work for a not-for-profit called European Centre for a Modern Ukraine, which was closely tied to Ukranian president Viktor Yankuovych. He is expected to register as a foreign agent representing Ukraine's interests between 2012 and 2014 in order to resolve lingering questions. Manafort worked on Trump's campaign for nearly five months in 2016, and led the campaign for about three months.
