Applicability of the Presidential Records Act to the White House Usher’s Office

Because the White House Usher’s Office is part of the President’s “immediate staff” or, alternatively, would be “a unit . . . of the Executive Office of the President whose function is to advise and assist the President,” any documentary materials “created or received [by the Office] in the course of conducting activities which relate to or have an effect upon the carrying out of constitutional, statutory, or other official or ceremonial duties of the President” constitute “Presidential records” under the Presidential Records Act, 44 U.S.C. § 2201(2).
