Before sending the document to a public database for federal court filings, lawyers for Manafort had tried to black out the portion on polling data and other information about Manafort's interactions with Konstantin Kilimnik, a former business partner of Manafort's who Mueller has claimed in court filings has ties to Russian intelligence.
The unredacted filing in the District of Columbia federal court says Manafort also discussed a Ukrainian peace plan with Kilimnik, a former employee of his consulting firm who the FBI assessed as having ties to Russian intelligence.
Mueller also said Manafort lied about contacting Trump administration officials after Trump took office.
Attorneys for Paul Manafort appeared to have mistakenly filed a court document Tuesday that made portions that were supposed to be redacted completely readable.
According to The Times, Manafort and Rick Gates, his former business partner and campaign deputy, provided the information in spring 2016, around the time Trump clinched the GOP nomination.
The Mueller prosecutors, who for 20 months have been investigating Trump campaign links to Russian Federation and whether Trump, as president, tried to illegally obstruct the probe, contended that Manafort lied about least five subjects.
It showed that Mueller had questioned Manafort on his discussions with Kilimnik in 2016 on a possible peace plan for Ukraine - where the two had worked together several years earlier for a pro-Russia political party.
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.
The lawyers wrote that Manafort was "sharing polling data. related to the 2016 presidential campaign".
Donald Trump’s speech on U.S.-Mexico border wall funding
Such asylum-seekers often present themselves at official crossing points, something that would not change if a wall were built. Cory Booker of New Jersey called it an effort to "extort funds" for an 'unnecessary and nonsensical border wall '.
"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.
Prosecutors said that they met 12 times with Manafort, and he testified twice to a grand jury, on October 26 and November 2.
Mr Kilimnik was considered Manafort's right-hand man in Ukraine and has been accused by the special counsel of conspiring to obstruct justice.
The filing claims that the first alleged lie by Manafort was "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", which they argue "did not constitute outreach to the President".
Manafort told a colleague in February - four months after he was indicted - that he was in contact with a senior administration official through that time, prosecutors said.
Manafort will not ask for a hearing regarding the prosecution's accusations, according to the filings.
But in Manafort's response, the electronic formatting for the redaction could easily be bypassed, revealing exactly what Manafort was accused of lying about.
The ex-Trump aide had been hoping for leniency at his 5 March sentencing under the plea deal.
