The U.S. Court of Appeals for the Third Circuit has upheld the Trump administration's removal of an exhibit documenting George Washington's enslaved workers from a federal building in Philadelphia. The city of Philadelphia challenged the decision, arguing that alterations to the display required municipal approval under local law.

Philadelphia filed suit in January, contending that the exhibit modifications amounted to changes to the building's interior that triggered city oversight requirements. The Third Circuit rejected this argument, finding that federal property and federal decision-making authority preempt local land-use and building codes.

The exhibit, which highlighted the lives of the enslaved individuals held at George Washington's Mount Vernon estate, had been displayed in the building. The Trump administration removed it as part of broader efforts to reshape how federal spaces address historical narratives around slavery and America's founding figures.

The Third Circuit's decision rests on principles of federal supremacy and immunity from local regulation. Federal buildings and federal agencies possess broad authority to control the use and presentation of space within their facilities without requiring approval from state or local governments. Philadelphia's argument that city building codes applied to the interior display faced a steep legal hill under established doctrine.

The ruling carries implications for how federal agencies manage exhibits and programming in facilities nationwide. Agencies retain authority to make curatorial and historical presentation choices independently, insulated from local zoning and building authorities. Cities cannot mandate specific content or require approval for alterations based on local ordinances.

The decision also reflects ongoing disputes over historical representation in public spaces. Museums, government buildings, and cultural institutions continue facing litigation and political pressure over which historical narratives receive prominence. This case confirms that federal institutions answer primarily to federal decision-makers, not local elected officials or building departments.

Philadelphia had positioned the litigation as a matter of procedural compliance with city code. The Third Circuit reframed it as a federalism question, where local authority stops at the federal building's threshold.
