In its filing, the defence was trying to rebut allegations that Manafort intentionally lied to special counsel Robert Mueller's team after he had agreed, last September, to co-operate with Mueller's investigation as well as plead guilty to charges of conspiracy against the United States and conspiracy to obstruct justice.
After leveling that accusation, prosecutors filed a heavily-redacted court document describing five areas in which Manafort is accused of lying to government investigators, including misleading statements about his contacts with Trump administration officials.
Paul Manafort had almost a month to respond to allegations that he lied to the Special Counsel's Office when he was supposed to be cooperating with them as part of his plea deal in his Washington, D.C. federal money laundering case.
The redaction errors in Manafort's rebuttal show prosecutors believed he had lied about sharing 2016 polling data with Mr Kilimnik, as well as meeting him in Madrid and discussing Ukrainian politics while Manafort was managing the Trump campaign.

The two men also discussed a peace plan for Ukraine, according to the court documents.
The defense lawyers said Manafort suffers from depression and anxiety, has had little contact with his family and, on days when he met with investigators, was awakened before dawn to have hourslong interviews with little time to prepare for the questioning.
Mueller's filing said Manafort "breached his plea agreement in numerous ways by lying to the Federal Bureau of Investigation", including about his interactions with Russian associate Konstantin Kilimnik.
"It is not surprising at all that Mr Manafort was unable to recall specific details prior to having his recollection refreshed", Manafort's team wrote. Manafort spokesman Jason Maloni said Tuesday the Madrid trip mentioned in the filing occurred in January or February 2017- months after Manafort was ousted from the campaign and as Trump was taking office.
In August, Manafort, 69, was convicted of financial fraud relating to his work as a political consultant in Ukraine, which pre-dated his role with Donald Trump's presidential campaign.More news: The San Antonio Spurs decimated the Toronto Raptors in Leonard’s return
Manafort dangled the briefings as he was mired in a dispute with Mr Deripaska over a multi-million-dollar deal involving a Ukrainian cable company.
Prosecutors have also accused Manafort of lying about his contacts with Trump administration officials, which defense lawyers deny.
"The first alleged misstatement identified in the Special Counsel's submission (regarding a text exchange on May 26, 2018) related to a text message from a third-party asking permission to use Mr. Manafort's name as an introduction in the event the third-party met the President", the redacted portion reads.
In the filing Manafort's lawyers said they would not seek an evidentiary hearing to contest Mueller's allegations of lying, arguing that such factual matters could be addressed in a pre-sentencing report.More news: Clemson overwhelms Alabama to claim second national title in three years
