Mueller also said he expects to file a sentencing submission in the case with Ellis later Friday.
Manafort, who has been in jail without bond since June after being accused of witness tampering in his cases, already is scheduled to be sentenced March 13 in the Washington case.
He had been scheduled to be sentenced in Virginia on Feb. 8. But that was postponed due to the dispute in the Washington case over whether Manafort had breached his plea deal with Mueller.
Manafort’s lawyers did not immediately respond to a request for comment from CNBC.
The longtime Republican operative was convicted Aug. 21 of eight felony counts — which included tax fraud, failure to file a report of a foreign bank and financial accounts, and bank fraud — after trial before Ellis in Virginia. A jury deadlocked on 10 other counts in that case.
That case related to income Manafort made while doing consulting for a pro-Russia political party in Ukraine, work that preceded his tenure as chairman of Trump’s presidential campaign in 2016.
On Sept. 14, Manafort pleaded guilty in Washington federal court to conspiracy charges, just three days before he was due to go on trial there. That case also related to his work in Ukraine.
Manafort as part of his plea agreed to cooperate with Mueller’s ongoing probe of Russian interference in the presidential election, and possible collusion by members of the Trump campaign in that meddling. President Donald Trump denies any wrongdoing by his campaign.
