Federal prosecutors are no longer required to argue in support of a reduced prison sentence for Paul Manafort, a federal judge ruled Wednesday, finding the special counsel had adequately demonstrated that the former Trump campaign chairman lied to authorities after pledging to cooperate.

The judge, Amy Berman Jackson, concluded that prosecutors are not obligated to advocate for a reduced sentence for Manafort, who pleaded guilty in September to various charges rooted in his lobbying work for Ukraine. The plea agreement followed Manafort’s conviction in Alexandria, Virginia, on multiple financial fraud charges.
