The special counsel in the Russia investigation is accusing former Trump campaign chairman Paul Manafort of violating his plea agreement by repeatedly lying to federal investigators, an extraordinary allegation that could expose him to a lengthier prison sentence — and potentially more criminal charges.
The torpedoing of Manafort's plea deal, disclosed in a court filing on Monday, also results in special counsel Robert Mueller's team losing a cooperating witness from the top of Donald Trump's presidential campaign who was present for several key episodes under investigation. That includes a Trump Tower meeting involving Donald Trump Jr. and a Russian lawyer he was told had derogatory information on Democrat Hillary Clinton.
The move signals a return to the acrimonious relationship Manafort has had with the special counsel's office since his indictment last year. Before his plea agreement, Manafort aggressively challenged the special counsel's legitimacy in court, went through a bitter trial and landed himself in jail after prosecutors discovered he had attempted to tamper with witnesses in his case.
In the latest filing, Mueller's team said Manafort 'committed federal crimes' by lying about 'a variety of subject matters' even after he agreed to truthfully cooperate with the investigation.
Prosecutors said they will detail the 'nature of the defendant's crimes and lies' in writing at a later date to the judge.
Through his attorneys, Manafort denied lying, saying he 'believes he provided truthful information' during a series of sessions with Mueller's investigators. He also disagreed that he breached his plea agreement. Still, both sides now agree they can't resolve the conflict, and US district judge Amy Berman Jackson should set a date to sentence him.
Manafort, who remains jailed, had been meeting with the special counsel's office since he pleaded guilty in September to conspiracy against the US and conspiracy to obstruct justice. He cut that deal to head off a second trial after being convicted last summer of eight felony counts related to millions of dollars he hid from the IRS in offshore accounts.
Both cases stemmed from his Ukrainian political work and undisclosed lobbying work he admitted to carrying out in the US in violation of federal law.
As part of his plea agreement, Manafort pledged to 'cooperate fully, truthfully, completely, and forthrightly' with the government 'in any and all matters' prosecutors deemed necessary. That included his work on the Trump campaign as well as his Ukrainian political work, which remains under investigation by the US attorney for the Southern District of New York.
Prosecutors there are looking into the conduct of longtime Democratic lobbyist Tony Podesta, former Obama White House counsel Greg Craig and former Republican congressman and lobbyist Vin Weber to determine whether they violated federal law by failing to register as foreign agents with the justice department. None of the men has been charged with any crimes.
As part of his plea deal, Manafort also forfeited many of his rights as well as his ability to withdraw the plea if he broke any of the terms.
In return, prosecutors agreed to not bring additional charges against him and to ask a judge for a reduction of his sentence if he provided 'substantial assistance.'
But with prosecutors saying he breached the agreement, Manafort now faces serious repercussions such as the possibility of prosecution on additional charges including the 10 felony counts prosecutors dropped when he made the deal.
Manafort already faces up to five years in prison on the two charges in his plea agreement. In his separate Virginia case, Manafort's potential sentencing under federal guidelines has not yet been calculated, but prosecutors have previously said he could face as much as 10 years in prison on those charges.
He is scheduled to be sentenced in that case in February. His co-defendant, Rick Gates, who spent a longer time on the campaign and worked on the Trump inaugural committee, has not had a sentencing date set yet. He continues to cooperate with Mueller.
