Bush administration officials unveiled a bold new assertion of executive authority yesterday in the dispute over the firing of nine U.S. attorneys, saying that the Justice Department will never be allowed to pursue contempt charges initiated by Congress against White House officials once the president has invoked executive privilege. Under federal law, a statutory contempt citation by the House or Senate must be submitted to the U.S. attorney for the District of Columbia, whose duty it shall be to bring the matter before the grand jury for its action." But administration officials argued yesterday that Congress has no power to force a U.S. attorney to pursue contempt charges in cases, such as the prosecutor firings, in which the president has declared that testimony or documents are protected from release by executive privilege. Mark J. Rozell, a professor of public policy at George Mason University who has written a book on executive-privilege issues, called the administration's stance "astonishing. That's a breathtakingly broad view of the president's role in this system of separation of powers," Rozell said. "What this statement is saying is the president's claim of executive privilege trumps all." The administration's stance "is almost Nixonian in its scope and breadth of interpreting its power. Congress has no recourse at all, in the president's view. . . . It's allowing the executive to define the scope and limits of its own powers," [Rozell said].
