The office of special counsel Robert Mueller III has accused former Trump campaign chairman Paul Manafort of breaching his plea agreement with special counsel prosecutors, writing in a Monday court filing that he committed federal crimes by lying to federal investigators.

In a status report filed late Monday, prosecutors asked U.S. District Judge Amy Berman Jackson of the District of Columbia to schedule a sentencing date for Manafort. They said Manafort's alleged breach of his plea agreement meant there was “no reason” to delay sentencing.

“After signing the plea agreement, Manafort committed federal crimes by lying to the Federal Bureau of Investigation and the Special Counsel's Office on a variety of subject matters, which constitute breaches of the agreement,” prosecutors wrote in the court filing.
