Judge Amy Berman Jackson effectively added about 3 1/2 years in prison to the sentence Manafort received last week from a different judge in the Eastern District of Virginia.
Jackson said Manafort could serve some of the prison sentence at the same time he was serving in prison for his other case. But the judge in Washington ultimately increased the total amount of prison time.
A federal judge in Virginia had sentenced Manafort to just under four years in federal prison and ordered that he pay $24.8 million in restitution and a $50,000 fine.
Charges in New York City
Separately on Wednesday, Manhattan District Attorney Cyrus Vance announced that a grand jury in New York City had returned an indictment of its own against Manafort.
