FBI and Justice Department are conducting an investigation into possible US ties to alleged corruption of Yanukovich, including the work of Paul Manafort's firm, reported CNN.
The investigation is broad and is looking into whether US companies and the financial system were used to aid alleged corruption by the party of former president Viktor Yanukovych, the statement said.
In addition, the United States are conducting a probe into the work of other firms linked to the former Ukrainian government, including that of the Podesta Group, the lobbying and public relations company run by Tony Podesta, brother of Clinton campaign chairman John Podesta.
So far, the FBI, the US Justice Department, as well as the Manafort have not responded to a request for comment.
As QHA reported earlier, Ukraine found evidence proving Yanukovych paid an Adviser to Trump Paul Manafort more than USD 12 million.
