The heavily redacted report filed in the criminal case against Manafort in Washington, D.C., comes more than a week after prosecutors accused the one-time Trump campaign chief of “committing federal crimes by lying to the Federal Bureau of Investigation and the special counsel’s office on a variety of subject matters” in breach of his plea agreement.

The report released Friday detailing those claims had been highly anticipated for its potential to shed light on Mueller’s investigation into Russian interference in the 2016 presidential election and possible collusion with the Trump campaign, an investigation that has been kept tightly under wraps.

Mueller said in the filing that after signing the plea agreement, Manafort stated he had no direct or indirect communications with anyone in the administration, but evidence demonstrates that Manafort authorized a person to speak on his behalf.

“Separately, according to another Manafort colleague, Manafort said in February 2018 that Manafort had been in communication with a senior administration official up through February 2018,” the special counsel wrote in the 10-page report.

The filing details four topics on which Manafort is alleged to have misled prosecutors. These also include his interactions with Konstantin Kilimnik, a Russian who ran the offshoot of Manafort’s firm in Ukraine and who was charged alongside Manafort with witness tampering earlier this year. An earlier filing from Mueller suggested the FBI believes Konstantin had ties to Russian intelligence in 2016. Kilimnik has remained out of reach of U.S. prosecutors.

In a heavily redacted passage, Mueller’s prosecutors wrote Friday that Manafort lied about an unknown topic that the two discussed. The filing suggests Mueller has electronic evidence and travel records to disprove Manafort’s claims. Additionally, prosecutors say Manafort lied about meeting with Kilimnik and about his role in the alleged conspiracy to tamper with witnesses.
