Trump Designates Oval Office as National Monument by Proclamation

President Donald Trump signed a proclamation on November 5 establishing the Oval Office as a national monument. The designation covers the Oval Office itself (Room 110), the Outer Oval Office (Rooms 106 and 108), and the Cabinet Room (Room 105). It was issued under section 320301 of title 54 of the United States Code, the Antiquities Act.

The proclamation directs the Secretary of the Interior, through the National Park Service, to manage the monument in a manner that protects its historic character, architectural integrity, and association with the presidency. It calls for a management plan that prioritizes preservation and requires documentation and review before substantial alterations. The document states that it does not restrict the president's authority to redecorate, select furnishings, or make ordinary operational and security modifications that do not substantially impair the historic structure or architectural character.

The White House and its grounds are already a National Historic Landmark administered as part of the President's Park. The proclamation notes that the Oval Office merits specific recognition as a discrete historic structure. It does not alter existing statutory exemptions for the White House under the National Historic Preservation Act or diminish Congress's authority over federal property.

Trump told reporters the designation would prevent future presidents from destroying or substantially reshaping the room. He has renovated the space during his second term. The order was signed the day after the midterm elections in which Republicans lost control of both chambers of Congress. Legal scholars have noted that the power of a subsequent president to revoke a national monument designation has not been fully tested in court.

The White House issued a fact sheet describing the action as ensuring preservation and proper care of the space that has served as the principal working office of the president for nearly a century. The monument boundaries are defined as the smallest area compatible with the proper care and management of the objects of historic interest. Management will involve coordination with the Committee for the Preservation of the White House and other advisory bodies.

The designation adds a formal layer of protection to rooms that have long been treated as historically significant. Its practical effect will depend on how future administrations and courts interpret the proclamation and the limits of the Antiquities Act when applied to the White House complex.
