Manafort suspected of sharing polling data with associate linked to Russian intelligence

A major court filing error led to secret details of former Trump campaign chairman Paul Manafort’s criminal case leaking out into the public sphere on Tuesday.

Defense attorneys filed a response contesting special counsel Robert Mueller’s allegations that Manafort lied to federal investigators on a variety of subjects, in breach of his plea agreement. But while portions of the filing were supposed to be redacted and shielded from the public, court watchers were able to view the filing in its entirety by copying and pasting the redacted sections.

The error resulted in Manafort’s attorneys disclosing that Mueller has accused Manafort of sharing polling data during the 2016 presidential campaign with Konstantin Kilimnik, a business associate who is suspected of ties to Russia’s military intelligence unit, the GRU.
