A federal judge has ordered the Trump administration to restore changes it made to displays and content at National Park Service historical sites, ruling against alterations that had removed or modified materials addressing contested aspects of American history. The order requires the administration to return affected sites to the condition they were in before the changes were implemented.

The ruling came in response to a lawsuit challenging the administration's modifications at sites that had previously included content critics said the administration sought to downplay or eliminate. The judge found sufficient legal grounds to mandate restoration while the broader legal challenge proceeds.

The National Park Service had made changes at multiple historical sites under the Trump administration, with opponents arguing the alterations stripped away important historical context about events and figures that the parks were established to commemorate and interpret. Supporters of the changes had argued the original content reflected a particular ideological framing that warranted revision.

The court's order adds to a series of judicial interventions in Trump administration decisions affecting federal agencies and their public-facing programs. It was not immediately clear how quickly the administration would be required to implement the restoration or whether it would appeal the ruling.
