Lawyers for Paul Manafort apparently mistakenly filed a court document Tuesday that revealed redacted material— including accusations Manafort shared 2016 campaign polling data with a Russian national linked to the Kremlin.

Defense attorneys for the former Trump campaign manager had filed a response Tuesday contesting special counsel Robert Mueller's allegations Manafort lied to federal investigators on a variety of subjects in breach of his plea agreement.

But according to The Hill, court watchers were able to see the whole filing by copying and pasting the redacted sections.

The goof resulted in Manafort's legal team revealing Mueller has accused Manafort of sharing polling data with Konstantin Kilimnik, a business associate suspected of ties to Russia's military intelligence unit, the GRU, during the 2016 presidential campaign, The Hill reported.

The filing also showed Manafort discussed a "Ukraine peace plan" with Kilimnik, according to the lawyers.

Mueller had previously accused Manafort of lying about his interactions with Kilimnik, a Russian national who used to run the offshoot of Manafort's consulting business in Ukraine.

Kilimnik has been charged alongside Manafort with witness tampering as part of Mueller's sprawling investigation into Russian interference and is believed to have links to the GRU, the Russian intel unit blamed for hacking Democrats' emails in 2016.

In another faultily redacted portion, Manafort's lawyers disclosed an unnamed third party texted Manafort last May asking to use his name as a point of introduction if the person met with President Donald Trump, The Hill reported.

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.

Manafort's attorneys disputed the characterization Manafort authorized the unnamed person to communicate with Trump on his behalf, according to the redacted details of the filing, The Hill reported.

Though there was no comment from Manaford's legal team, a new, corrected filing was quickly posted on the docket that no longer allowed the public to see the redacted paragraphs, The Hill reported.
