Trump signs proclamation designating Oval Office and Cabinet Room a national monument
Where it stands
The official proclamation establishes the Oval Office National Monument under the Antiquities Act and directs preservation review, but it does not impose Trump's stated blanket requirement for congressional approval of every major change.
Sources reviewed: Nov 5, 2026 · 9:01 PM EST
President Donald Trump's November 5 proclamation invokes the Antiquities Act and establishes the Oval Office National Monument. The defined monument includes Oval Office Room 110, Outer Oval Office Rooms 106 and 108, and Cabinet Room 105.
The proclamation directs the Interior Department and National Park Service to prepare a management plan, document existing conditions, study alternatives and review preservation effects before substantial alteration or demolition. It also directs evaluation of changes affecting historic character.
The response.
Trump said major modifications would require congressional approval and described the designation as protection against destruction or substantial alteration. The official text does not contain that blanket condition. It expressly preserves presidential authority to redecorate, select furnishings and make ordinary operational or security modifications that do not substantially impair historic structure or character, while stating that it does not diminish Congress's constitutional authority over federal property. AP reported that proclamations can be reversed and noted that Trump has rolled back earlier national-monument designations. No court ruling on this proclamation was identified.
