Special Counsel Robert Mueller said in a court filing Friday that former Trump campaign manager Paul Manafort lied about his contacts with the Trump administration after President Donald Trump took office.

In the heavily redacted document, Mueller also said that Manafort lied about his communications with Konstantin Kilimnik, an alleged Russian intelligence agent.

As summarized above, in his interviews with the Special Counsel’s Office and the FBI, Manafort told multiple discernible lies–these were not instances of mere memory lapses. If the defendant contends the government has not acted in good faith, the government is available to prove the false statements at a hearing. Further, to the extent that the defendant contests specific false statements that implicate ongoing investigations, the government is available to provide relevant evidence to the Court ex parte.

Manafort pleaded guilty to conspiracy charges in September and is scheduled to be sentenced in March.
