Overview
- Led by the National Parks Conservation Association, conservation, history and science groups filed a federal suit challenging President Trump’s March 2025 directive to remove what the administration calls “corrosive ideology.”
- The complaint says parks have altered or removed materials on slavery, Indigenous history, climate science, sexism and LGBTQ rights, citing examples at Philadelphia’s President’s House Site, the Selma to Montgomery trail, Brown v. Board of Education, Grand Canyon and Acadia.
- Interior Secretary Doug Burgum is named as a defendant, and the lawsuit says the National Park Service has identified hundreds of signs and exhibits for removal nationwide.
- A federal judge in Pennsylvania ordered the Philadelphia slavery exhibit restored, and the Interior Department says it has appealed while asserting updated materials were forthcoming.
- Separately, community groups filed a New York lawsuit over the removal of the Pride flag at the Stonewall National Monument.
