A review of the historical experience and legal rulings pertinent to congressional access to information regarding the law enforcement activities of the Department of Justice indicates that in the last 85 years Congress has consistently sought and obtained deliberative prosecutorial memoranda, and the testimony of line attorneys, FBI field agents and other subordinate agency employees regarding the conduct of open and closed cases in the course of innumerable investigations of Department of Justice activities.
