NBC News reported last March that Manafort was associated with at least 15 bank accounts and 10 companies in Cyprus. And The New York Times discovered in
August 2016 that the Party of Regions designated nearly $13 million in undisclosed cash payments in Manafort's name.
The Atlantic also published several emails last year that appeared to show Manafort using his elevated role in the Trump campaign to resolve a financial dispute with Russian oligarch Oleg Deripaska.
Manafort was also one of three top Trump campaign officials who attended a June 2016 Trump Tower meeting with two Russian lobbyists who offered the campaign dirt on then-Democratic candidate Hillary Clinton.
