On July 24, 2026, President Donald Trump signed an executive order directing the Interior Department to install temporary signs along National Park Service walkways leading into the Smithsonian National Museum of American History, accusing the institution of exhibit inaccuracy and ideological capture. The order, titled "Restoring Trust in the Smithsonian Institution," tasks Interior Secretary Doug Burgum, the National Park Service, and Assistant to the President for Domestic Policy Vince Haley with creating and placing the signage (The Guardian, 2026-07-25; White House, 2026-07-24).

The signs are required to notify visitors that museum exhibits should be renovated consistent with findings in a White House report and direct the public to other sources for American history information. The same group of officials is also directed to produce separate signs criticizing the Smithsonian for not sufficiently commemorating the Declaration of Independence during its 250th anniversary year (White House, 2026-07-24).

The order states that the National Museum of American History "failed to appropriately honor the 56 signers of the Declaration of Independence during this 250th anniversary year of the founding of our country" (White House, 2026-07-24). The United States semiquincentennial, marking 250 years since the 1776 Declaration, provides the political backdrop for the administration's pressure campaign.

The directive draws on a Domestic Policy Council report completed after a months-long review of the Smithsonian Institution and its National Museum of American History. The full title of the report is "Saving America's Story: How Ideological Capture at the Smithsonian Institution's National Museum of American History Erases Our Heritage." The report accuses the Smithsonian's leadership of "ideological capture" (The Guardian, 2026-07-25; White House, 2026-07-24). The National Museum of American History declined to comment on the order (The Guardian, 2026-07-25).

Section 2 of the order broadens the mandate beyond signage. It directs the Secretary of the Interior, the Director of the Office of Management and Budget, the Administrator of General Services, and the Assistant to the President for Domestic Policy to identify and utilize all available authorities to restore trust in the Smithsonian Institution (White House, 2026-07-24). The White House published an accompanying fact sheet, "Fact Sheet: President Donald J. Trump Restores Trust in the Smithsonian Institution," on the same day (White House, 2026-07-24).

The July 24 order does not emerge in isolation. It cites Executive Order 14253, "Restoring Truth and Sanity to American History," issued on March 27, 2025 (White House, 2026-07-24). That earlier order was accompanied by its own fact sheet and was followed in August 2025 by a "Letter to the Smithsonian: Internal Review of Smithsonian Exhibitions and Materials" (White House, 2025-08-12; White House, 2025-03-27). Together, these documents form a sequence: an initial executive order, a formal letter initiating review, a months-long institutional audit by the Domestic Policy Council, and now a follow-on order demanding physical signage outside the museum itself.

The mechanism is unusual. Rather than pursuing changes to the Smithsonian through its Board of Regents or congressional appropriation hearings, the order deploys the National Park Service, which maintains the walkways surrounding the museum on the National Mall. This gives the Interior Department physical access to the public approach to a Smithsonian facility without requiring the Smithsonian's cooperation for installation. The Smithsonian Institution, while partially federally funded, operates as a trust instrumentality. The order's invocation of the NPS's jurisdiction over surrounding walkways appears designed to circumvent that institutional autonomy.

The broader stakes extend beyond a single museum's signage. Section 2's directive to OMB, GSA, and the Domestic Policy Council to use "all available authorities" signals potential leverage through budgetary and facilities channels. OMB controls the federal appropriation that flows to the Smithsonian. GSA manages federal real estate and procurement. The combination of fiscal, procurement, and physical-access tools gives the administration multiple pressure points short of direct editorial control over exhibit content.

The Smithsonian's institutional response so far has been limited to a decline to comment from the National Museum of American History. Whether the institution challenges the order, complies with the signage directive, or seeks congressional intervention remains an open question. The Board of Regents includes congressional members, which could become a forum for pushback. But the order's reliance on NPS walkways rather than Smithsonian property means that compliance may not be required from the institution itself for the signs to go up.
