A federal judge has ordered the Biden administration to restore signs and exhibits at national parks that the Trump administration removed, citing concerns over censorship and the integrity of historical and scientific information.
U.S. District Judge Angel Kelley in Boston issued a preliminary injunction requiring the Department of the Interior to reinstall signs related to topics such as slavery and climate change within 21 days. The ruling follows a lawsuit filed by groups including the National Parks Conservation Association and the American Association for State and Local History, which argued that the removal of these signs amounted to censorship and undermined the historical and scientific accuracy of national parks.
The Trump administration had removed these signs citing a desire to prevent what they called a “revisionist movement” that portrayed the U.S. as “inherently racist, sexist, oppressive, or otherwise irredeemably flawed,” according to an executive order signed in March 2025. The order directed the Department of the Interior to make changes to parks, monuments, and memorials to address what the White House described as “false revision of history.”
The plaintiffs contended that the removals violated congressional mandates governing over 430 national park sites and lacked lawful justification. The Interior Department stated that its policy aimed to ensure parks tell the “full and accurate story of American history,” but did not specify how the signs were removed or what criteria were used.
Legal Victory Reinforces Historical and Scientific Integrity
This ruling underscores the importance of maintaining accurate and comprehensive historical and scientific information in national parks. It signals a legal stance against efforts to selectively erase or alter historical narratives, which could have broader implications for how history is presented in public spaces and the role of government in shaping historical memory.

Background of Sign Removal and Political Motivations
The removal of signs and exhibits from national parks began after an executive order in March 2025 signed by President Donald Trump, targeting what he called a “revisionist movement” that portrayed America as inherently racist or oppressive. The order prompted the Department of the Interior to remove or alter signs addressing topics like slavery, climate change, and other contentious issues. Critics argued that these removals were motivated by political ideology and amounted to censorship, undermining the educational mission of national parks. The lawsuit challenging these removals was filed by conservation and historical groups, emphasizing the legal and ethical questions surrounding government control over historical narratives.
“The removal of these signs not only undermines the integrity of the National Parks but sets a dangerous precedent of censorship and sanitization.”
