Under the authority of Article II, Section 2, Congress has vested in the Attorney General the power to conduct the criminal investigation of the U.S. government. It has also vested in him the power to appoint subordinate officers to assist him in the discharge of his duties. Acting pursuant to those statutes, the Attorney General has delegated the authority to represent the United States in the particular matters to a Special Prosecutor with unique authority and tenure. The regulation gives the Special Prosecutor explicit power to contest the invocation of executive privilege in the process of seeking evidence deemed relevant to the performance of these specially delegated duties.
