The office of special counsel Robert Mueller III 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.
