Overview
- President Trump issued an executive order on July 24 directing the Department of the Interior and the National Park Service to install temporary signs and exhibits on NPS‑maintained walkways outside the National Museum of American History that say the museum is ideologically captured.
- The order cites a 162‑page Domestic Policy Council report released on July 4 that accuses museum leaders of promoting a 'radical' view of U.S. history and calls for exhibits to be renovated and corrected.
- NMAH Director Anthea Hartig defended the museum’s scholarship and nonpartisanship during congressional testimony on July 21–22, while Republican lawmakers pressed her over alleged bias and contested displays.
- Reporting links outside conservative advisers, notably David and Tim Barton of WallBuilders, to the administration's critiques and the order contains language that threatens review of federal funding and contract compliance as leverage.
- Smithsonian officials and major museum and history associations have publicly rejected the report’s findings, installation plans and timing remain unclear, and observers say the dispute could next move to board appointments, funding reviews, congressional action or legal challenges.
