Mueller broke off the plea agreement November 26 telling a judge who will oversee sentencing that Manafort continued to commit crimes, which violated the arrangement.
In the new court filing disclosed Tuesday, Manafort's lawyers decided not to contest the allegations that Manafort lied and asked a judge to move on to sentencing Manafort in the coming weeks.
While some of the redacted information was not a big deal, there was one section of the failed redaction that appears to shed light on Mueller's understanding of Manafort's roll in the 2016 presidential election.
What remains unknown is whether Trump or others on the campaign were aware that Manafort provided Kilimnik and Deripaska with polling data.
Mueller has claimed that Manafort, a political consultant, lied about his communications with Konstantin Kilimnik, who served as a translator and fixer on campaigns in Ukraine for a decade. (See Doc. 460 at 6). This includes his connection with former business partner Konstanin Kilimnik, a Ukrainian accused by prosecutors of having ties to Russian intelligence.
Defense lawyers say that even though they don't believe Manafort intentionally made false statements, they're not requesting a hearing on the government's allegations. Tuesday's filing revealed the first extensive details of what he lied about.
It's only a matter of time until those fake Craigslist job listings to be Manafort's new attorney to crop up so we might as well revel in this ongoing fever dream of incompetence. Manafort, who has been in solitary confinement, has suffered for several months from severe gout, according to the filing.
Mueller accused Manafort in December of authorizing a third party to communicate on his behalf with an "administration official", despite him telling investigators he did not recall direct or indirect communications with administration officials.
The filing says that a May 26, 2018, text message exchange with Manafort involved an unidentified "third-party" who was asking permission to name-drop Manafort if the person met with Trump.
The lawyers assented to these allegations by special counsel while arguing that, even though Manafort initially misled the government about these facts, they can not show that he was actually "lying" because the events "simply were not at the forefront of Mr. Manafort's mind". Mark Warner, D-Va., senior Democrat on the Senate Intelligence Committee, called information in filing "damning evidence of a senior Trump campaign official providing information to individuals tied to Russian intelligence in the midst of the Kremlin's effort to undermine our election".
"Mr. Manafort provided complete and truthful information to the best of his ability", Manafort's lawyers wrote.
The case is U.S. v. Manafort, 17-cr-201, U.S. District Court, District of Columbia (Washington).
Manafort was convicted in federal court in Virginia in August of bank fraud and tax evasion connected to his work in Ukraine. He is due to be sentenced in that case next month.
Under the agreement with prosecutors in his District case, Manafort also was ordered to forfeit an estimated $15 million he hid from the IRS, but was permitted to keep some property held with relatives.
Prosecutors said Manafort also lied about the circumstances of a $125,000 wire transfer in 2017.
