Special counsel Robert Mueller said in a court filing Monday that Paul Manafort had breached his plea agreement by lying to investigators since signing the agreement.
In the status report, which was filed after the parties had asked for a delay in the previous deadline, Manafort denied that he had not been cooperative.
Mueller and Manafort had come to the plea agreement in October, just before the case against the former Trump campaign chairman in D.C. was about to go to trial. A jury in Virginia convicted Manafort in the case Mueller brought against him there, where the charges focused on bank fraud and tax fraud allegations that mostly predated the 2016 campaign.
In the plea deal, Manafort plead guilty to conspiracy against the U.S. and obstruction of justice, related to allegations of witness tampering.
ABC News reported earlier this month that tensions had been rising between Manafort and Mueller’s team over Manafort’s level of cooperation.
