Manafort's sentencing judge, T.S. Ellis III, ruled that any talk of Russian collusion was off limits during the trial. Mueller's prosecutors have so far not taken a position on what Manafort's sentence should be, although they are expected to weigh in during the Washington hearing on whether the sentences should be concurrent or consecutive.
Manafort is facing 19 to 24 years in prison under sentencing guidelines - essentially a life sentence for the 69-year-old Republican consultant who was found guilty in August of charges that include bank and tax fraud. Manafort had pleaded not guilty to all 18 counts in the case.
This was well below U.S. federal sentencing guidelines, which called for a term of roughly 20 years, though few observers had expected Manafort to receive a sentence that long.
The government says Manafort's misconduct involved more than $16 million in unreported income, more than $55 million hidden in foreign bank accounts and more than $25 million secured through lies to banks. He said he hoped to have an opportunity "to show the world who I know I really am". It stems from his overseas work advising politicians in Ukraine.
Manafort is the only one of the 34 people and three companies charged by Mueller to have gone to trial.
Ellis also noted during the hearing that Manafort "is not before the court for any allegations that he, or anyone at his direction, colluded with the Russian government to influence the 2016 election".
In January, Manafort's defense attorneys accidentally unsealed court documents that revealed he had shared Trump campaign polling data with a business associate with Russian ties.
In just under a week, on March 13th, he faces a second sentencing hearing in federal court in Washington, D.C. on felony counts that he pleaded guilty to a year ago.

Federer surgically broke serve in the first game and took the set on his fourth set point. I think that was a secret for me. I think this number proves that.
While he faces a statutory maximum of 10 years in the Washington case, U.S. District Judge Amy Berman Jackson potentially could stack that on top of the sentence imposed in the Virginia case, rather than allowing the sentences to run concurrently.
Trump has also dangled the possibility of pardons for some of those indicted - including Manafort, who he has praised as a "good man" who has been treated unfairly.
He added, "I ask you to be compassionate".
"The cases that the special counsel have brought against Mr. Manafort have devastated him personally, professionally and financially", they wrote in a March 1 filing.
Manafort faces another sentencing next week in a Washington D.C. courtroom, where he could be handed a prison term of up to 10 years. It was not related to Manafort's role in Donald Trump's presidential campaign.
In reality, they said, he was under Justice Department investigation before Mueller was appointed special counsel in May 2017.
No, Manafort has not been charged with anything related to the special counsel's investigation into an alleged Russian plot to influence the 2016 United States presidential election.
Manafort argued he deserves credit for accepting responsibility and working with the special counsel, although a D.C. judge determined he lied to investigators after his plea.
