In a court filing Monday, the office of special counsel Robert Mueller said that former Trump campaign chair Paul Manafort repeatedly lied to investigators, invalidating his plea deal. The court documents do not detail the lies, but both prosecutors for the special counsel and Manafort’s lawyers have asked the judge in the case to move to sentencing Manafort. Meanwhile, former Trump adviser George Papadopoulos reported to federal prison in Wisconsin Monday to start a 14-day sentence. Papadopolous pleaded guilty last year to lying about his communications with Russian contacts during the 2016 presidential campaign.
