The decision to call him out as a liar effectively takes his testimony off the table, removing a valuable asset for the government. It comes after a lengthy trial where prosecutors won guilty verdicts against Trump’s former campaign chairman. “They viewed him as giant prize and that’s why they were willing to take the risk of exposing parts of the investigation by going to trial,” said Seth Waxman, a lawyer and former federal prosecutor in D.C. “To lose the cooperation of Manafort is a devastating loss for the government.” The government has accused Manafort of breaching his plea agreement by repeatedly lying to federal investigators. It asked a federal judge on Monday to move forward with Manafort’s sentencing just more than two months after he began cooperating. Mueller’s prosecutors wrote that Manafort lied to the FBI and the special counsel’s office “on a variety of subject matters,” saying they would file a “detailed sentencing submission” to the probation department and federal court laying out the nature of his lies.
