The former campaign chairman for Donald Trump, Paul Manafort has turned himself into Justice Department special counsel Robert Mueller.
Former Trump campaign official Rick Gates has also been told to turn himself in.
The two are expected to be processed separately, according to a law enforcement official. They will later be transported to federal district court in Washington.
The indictments are expected to be unsealed later today as the extent of the charges is not immediately known.
Before this indictment, the FBI in July executed a search warrant at Manafort’s home in Alexandria, Virginia, seizing financial and tax documents, including some that had already been provided to congressional investigators.
