Six prominent national nonprofit organizations focused on the preservation of national parks, history, and science have initiated legal action against the Trump administration. This lawsuit addresses the administration's efforts to censor certain signage in national parks across the United States.
The plaintiffs, including the National Parks Conservation Association and the American Association for State and Local History, filed a comprehensive sixty-page lawsuit in the U.S. District Court of Massachusetts. The suit names the U.S. Department of the Interior and its officials as defendants.
According to the lawsuit, the Trump administration is accused of conducting a "sustained campaign to erase history and undermine science." This alleged campaign contradicts the legal requirements for national parks to reflect diverse cultural backgrounds and current scientific research.
Specific examples cited in the lawsuit include the removal of an exhibit at Independence National Historical Park discussing the legacy of enslaved individuals and the omission of climate change information at Fort Sumter, recognized as one of the most environmentally threatened parks in the nation. The lawsuit claims that historical and scientific data have been erased from numerous national parks.
In March 2025, an executive order was issued that mandated the removal of monuments and markers that did not align with the administration's narrative. This order criticized what it termed a "revisionist movement" and aimed to promote a more favorable view of American history.
Additionally, the Secretary of the Interior's directive included provisions for QR codes on park signage, allowing visitors to report any information deemed negative. However, public feedback largely rejected these efforts, as indicated by a review from National Public Radio and the Sierra Club, both of which found overwhelming disapproval of the administration's attempts to sanitize history.
Despite the public outcry, the National Park Service has reportedly identified hundreds of signs and materials for removal. This includes displays at Jamaica Bay Wildlife Refuge that addressed historical injustices and explanations of climate change at Glacier National Park.
The lawsuit argues that these actions violate congressional mandates regarding the management of national parks and undermine the mission of the National Park Service to preserve these spaces for education and inspiration.
The National Parks Service acknowledges its role as "America's largest classroom" and emphasizes the importance of sharing a comprehensive and truthful history. The plaintiffs are seeking a court order to halt the removal of historical and scientific information and to restore what has already been taken down.
