Trump is removing Geoffrey Berman as Manhattan's chief federal prosecutor, Attorney General William Barr says. Attorney General William Barr on Saturday informed Manhattan's chief federal prosecutor, Geoffrey Berman, that President Trump was removing him from office after the prosecutor refused to resign.
