According to a report from Talking Points Memo, "Manafort’s attorneys appear to have made a mistake in the filing, allowing redacted portions to be revealed via copying and pasting the text to a new document. Most of what’s revealed relates to Manafort associate Konstantin Kilimnik, a Russian national who Mueller has linked to a Russian intel agency."
TPM adds, "Manafort’s attorneys write that he 'conceded' to special counsel prosecutors that he discussed a 'Ukraine peace plan' with Kilimnik 'on more than one occasion,' and that he is accused of lying to the government about 'sharing polling data with Mr. Kilimnik related to the 2016 presidential campaign.'"
The Washington Post notes that the "apparently inadvertent revelation indicates a pathway by which the Russians could have had access to Trump campaign data."
UPDATE: 4:04 PM ET –
On MSNBC former Assistant Director for Counterintelligence at the FBI, Frank Figliuzzi, describes Kilimnik as a "known" Russian agent.
