in january 2019, paul manafort's lawyers submitted a filing to the court, in response to the robert mueller special counsel's accusation that manafort had lied to investigators while supposedly co-operating with the investigation. through an error in redacting, the document accidentally revealed that while manafort was donald trump's campaign chairman, manafort met with konstantin kilimnik, gave kilimnik polling data related to donald trump's 2016 united states presidential campaign, and discussed a ukraine-russia peace plan for the ongoing russia invasion of ukraine with kilimnik. as a russian main intelligence directorate gru agent, konstantin kilimnik is known member of russia's intelligence community. although most of the polling data was reportedly public, some was private trump campaign polling data managed by brad parscale. manafort asked kilimnik to pass the data to ukrainians serhiy lyovochkin and rinat akhmetov.
