(CNBC) -- Special counsel Robert Mueller is asking a judge to grant immunity from prosecution for five potential witnesses whose testimony Mueller wants to compel at the upcoming federal criminal trial of former Trump campaign chief Paul Manafort, according to a court filing Tuesday.
The five individuals would either refuse to take the witness stand, or refuse to answer questions because of their Fifth Amendment right against self-incrimination if they are not granted immunity and compelled to testify with that protection from prosecution, according to Mueller's filing in U.S. District Court in Alexandria, Va.
Mueller has also asked Judge T.S. Ellis to seal the court motions detailing the witnesses.
