(a) An individual named as Special Counsel shall be a lawyer with a reputation for integrity and impartial decisionmaking, and with appropriate experience to ensure both that the investigation will be conducted ably, expeditiously and thoroughly, and that investigative and prosecutorial decisions will be supported by an informed understanding of the criminal law and Department of Justice policies. The Special Counsel shall be selected from outside the United States Government. Special Counsels shall agree that their responsibilities as Special Counsel shall take first precedence in their professional lives, and that it may be necessary to devote their full time to the investigation, depending on its complexity and the stage of the investigation.
(b) The Attorney General shall consult with the Assistant Attorney General for Administration to ensure an appropriate method of appointment, and to ensure that a Special Counsel undergoes an appropriate background investigation and a detailed review of ethics and conflicts of interest issues. A Special Counsel shall be appointed as a “confidential employee” as defined in 5 U.S.C. 7511(b)(2)(C).
