A coalition of conservation and historical groups filed a lawsuit on Tuesday against the Trump administration. The lawsuit claims that new policies under President Donald Trump and Interior Secretary Doug Burgum have removed or censored history and science in U.S. national parks. The Boston-based suit says that park staff were ordered to take down exhibits that share accurate information about slavery, civil rights, Indigenous history, and climate change. Advocacy groups warn this erases key parts of American history and science. The same day, LGBTQ+ rights groups and preservationists filed a separate lawsuit over the removal of a rainbow Pride flag at the Stonewall National Monument in New York. The site commemorates the start of the modern LGBTQ+ rights movement. Officials removed the banner citing a memo that limits federal displays to certain flags, although some exceptions remain for historical context. Advocates argue the Pride flag offered essential historical context, while Confederate and other historical banners continue to be displayed at various sites. Local politicians raised a new Pride flag at Stonewall shortly after the removal. The lawsuits follow Trump’s executive order aimed at “restoring truth and sanity to American history.” It instructed federal agencies to remove elements that could “disparage Americans past or living.” Burgum later clarified this included eliminating “improper partisan ideology” from museums, monuments, and other federal exhibits. Groups filing the Boston lawsuit said the review of interpretive materials has accelerated recently. Exhibits discussing slavery, civil rights, Indigenous peoples, climate science, and other core historical topics are being removed nationwide. In Philadelphia, the Independence National Historical Park saw panels removed that described nine enslaved people living at George Washington’s home in the 1790s. A federal judge ordered the exhibits restored on Presidents’ Day while the legal challenge continues. Elsewhere, the Selma to Montgomery National Historic Trail in Alabama flagged roughly 80 items for removal. Brown v. Board of Education National Historical Park in Kansas is under review because its exhibit mentions “equity.” At the Grand Canyon, signage referencing Native American displacement and resource exploitation disappeared. Glacier National Park in Montana had materials about climate change and shrinking glaciers removed. Alan Spears, senior director of cultural resources at the National Parks Conservation Association, said, “Censoring science and erasing America’s history at national parks threatens the purpose of these amazing places.” He added, “National parks serve as living classrooms. Visitors deserve to learn both triumphs and tragedies of our history.” Jeff Mow, retired Glacier superintendent, called Trump’s order “a disservice to the public” and said it hampers park staff from telling the full story. Skye Perryman of Democracy Forward said, “You cannot tell America’s story without showing both beauty and tragedy.” The Interior Department appealed the Philadelphia ruling, stating that updated exhibits on slavery would have been installed soon anyway. White House spokeswoman Taylor Rogers described the new lawsuit as “premature” and based on “inaccurate information.” Judge Cynthia Rufe, a George W. Bush appointee, compared the Trump administration’s actions to George Orwell’s 1984, citing efforts to rewrite historical records to match the administration’s narrative. She barred officials from replacing the removed exhibits with materials that tell history differently. The lawsuits highlight ongoing tension over Trump park policies and raise broader questions about how America presents its history and science in national parks.
