"I have not even given it a thought", he added, when asked about a potential pardon.
Manafort pleaded guilty September 14 in the Washington case to a wide-ranging conspiracy involving obstruction of justice, money laundering, secret overseas bank accounts and false statements to the Justice Department. He pleaded with the judge not to impose any additional prison time.
The breadth of Manafort's criminal activity - and his own written agreement with prosecutors - led to a recommended sentence double that amount.
Manafort has asked for mercy given his age and fragile health, while arguing that Special Counsel Robert S. Mueller III prosecuted him in fruitless pursuit of evidence that the Trump campaign colluded with the Russian government.
Manafort's lawyers countered that their client should be given credit for admitting his guilt while also stressing that none of the Mr Mueller's charges related to the special counsel's core mandate: collusion between Russian Federation and the Trump campaign. Shortly before the NY announcement, Manafort, 69, was ordered to serve an additional 43 months on federal conspiracy charges, bringing his total sentence between two federal courts to 7.5 years in twin cases stemming from the Mueller probe.
At his sentencing hearing, Manafort said he was sorry for what he had done.
The political environment since Manafort's indictment has been "very harsh", attorney Kevin Downing told the judge.
"I believe that is not reflective of someone who has learned a harsh lesson".
"The most damning thing she said was she accused him of not being candid with her during the sentencing".
Jackson said Manafort's crimes were "not just a failure to comply with some pesky regulations" but "lying to the American people and the American Congress".
"The no-collusion mantra is simply a non sequitur", she said, suggesting that those arguments were meant for an audience outside the courtroom - presumably a reference to the president, who has expressed sympathy for Manafort and not ruled out a pardon.
Manafort was facing up to 10 years in prison in the D.C. case, which stemmed from alleged money laundering in connection with money Manafort earned for political work in Ukraine. That makes seven and one-half years for Manafort, coming on top of the roughly four-year term he received last week in a separate case in Virginia.
The issue of whether Manafort might have been involved with the Russians who interfered in the 2016 election is a red herring, Jackson said, unconnected to his actual court case.
The jury was unable to reach a verdict on 10 counts, including conspiracy to commit bank fraud and bank fraud. He was convicted at trial in the Virginia case and pleaded guilty in Washington to two conspiracy counts, each punishable by up to five years in prison.
But Manafort admitted guilt on all charges in his Washington plea.
