Historical revisionism
Altering, removing, or reframing the interpretive content of a government-controlled historical site, memorial, exhibit, or educational material for ideological reasons rather than to correct an inaccuracy -- whether by replacing existing content with an ideologically preferred narrative, or by deleting it outright without a replacement. The marker is ideological motive, not the presence of substitute content: removal driven by a desire to erase an unflattering-but-accurate account qualifies even with nothing put in its place. Excludes corrections made to fix a factual error or incorporate new scholarship. Distinct from state-sponsored-disinformation (fabricating or spreading new false claims) in that the mechanism here acts on existing accurate content at an official site of record.

Washington Post revealed Defense Department stripped slavery context from Arlington's Confederate memorial marker
The Washington Post reported on September 7, 2026, that the Trump administration had removed language critical of Confederate history from a marker and Defense Department website describing the Confederate Memorial at Arlington National Cemetery; the exact date the text changed is not established in the reporting. The removed passages described the 32-foot bronze statue as presenting a "nostalgic, mythologized vision of the Confederacy, including highly sanitized depictions of slavery," and the replacement marker states only that the statue will return to the site in 2027 after conservation. The Defense Department referred questions to Arlington National Cemetery, which did not respond to the newspaper.
Trump signed executive order directing warning signs placed outside National Museum of American History labeling exhibits inaccurate
On July 24, 2026, President Trump signed an executive order titled "Restoring Trust in the Smithsonian Institution," directing the Secretary of the Interior, the OMB Director, the GSA Administrator, and the Domestic Policy Assistant to install temporary warning signs on National Park Service-maintained sidewalks outside the National Museum of American History, notifying visitors that the museum's exhibits "should be renovated" and directing them to alternate resources. The order referenced a July 4, 2026 White House Domestic Policy Council report accusing the museum of treating American history as a tool for social justice advocacy. The Smithsonian Institution declined to comment.
National Park Service replaced the President's House slavery exhibit in Philadelphia overnight, softening Washington's role as enslaver
On July 15, 2026, the National Park Service completed an overnight swap of the interpretive exhibit at the federally owned President's House Site in Philadelphia, installing Trump administration-proposed panels that historians say soften George Washington's role as an enslaver of nine people at the site. Workers replaced the displays "under the cover of darkness," in the mayor's words, days after the Third Circuit ruled that Philadelphia had no legal authority over interpretive content at the federally owned memorial. The new panels devote more space to the early presidency and recast Washington's views on slavery, drawing condemnation from Philadelphia's mayor and civil-rights advocates.
Interior/NPS database flags hundreds of park signs on slavery, civil rights, climate for removal
An internal Department of the Interior and National Park Service database, authenticated by The Washington Post with current federal employees, flags several hundred signs, exhibits, films, and books across national park sites for removal or revision under President Trump's order to scrub "partisan ideology" and content that "disparages" Americans. Flagged materials include exhibits on slavery, the civil rights movement, Japanese-American internment, racial violence, and climate science — among them at least 30 signs at Harpers Ferry National Historical Park. Some materials had already been removed when the database was reported on March 2, 2026, while the department said final decisions on others had not been made.
National Park Service removed the Pride flag from Stonewall National Monument, the birthplace of the modern LGBTQ rights movement
On February 10, 2026, the National Park Service quietly removed the Pride flag — which had flown for years at the Stonewall National Monument in Manhattan and includes colors representing the transgender community — citing a Department of the Interior directive limiting NPS flagpoles to the U.S. flag and other "congressionally or departmentally authorized" flags. A coalition of LGBTQ+ nonprofits sued a week later, arguing NPS's own policy exempts flags that provide historical context — the same exception that allows Confederate flags at sites like Gettysburg — and the Trump administration settled on April 13, 2026, agreeing to restore the flag permanently within seven days.
CBP removed civil rights history, including a James Meredith desegregation story, from its website during Black History Month
U.S. Customs and Border Protection deleted several historical "Did you know?" stories from its public website between February 2 and February 9, 2026, during the 100th anniversary of Black History Month. The removed content included an account of Border Patrol agents protecting James Meredith during the 1962 desegregation of the University of Mississippi, along with biographies of Black explorer Matthew Henson and other Black and female CBP figures, all of which had been posted by CBP since March 2014. A CBP spokesperson told Unraveled the agency was "looking into" the removals but did not explain them.
National Park Service removed the George Washington slavery exhibit at Philadelphia's President's House Site
On January 22, 2026, the National Park Service removed 34 educational panels documenting the nine people George Washington enslaved while living at the President's House in Philadelphia, implementing President Trump's March 2025 executive order directing federal cultural sites to remove content that "inappropriately disparages" Americans. The city of Philadelphia sued, and a federal judge ordered the exhibit restored in February 2026, but the Third Circuit reversed that injunction in June, and NPS installed replacement panels in July that critics say soften Washington's record on slavery; Philadelphia is now seeking a rehearing of the appellate ruling.

U.S. Army removed its webpage honoring civil rights pioneer Sarah Keys Evans under the Pentagon's DEI content purge
In July 2025, the U.S. Army removed from its official website a 2014 article honoring Sarah Keys Evans, a Black Women's Army Corps veteran whose 1952 arrest for refusing to give up a bus seat helped desegregate interstate travel. The removal was carried out under a February 2025 Defense Department directive, issued at the direction of Secretary Pete Hegseth, ordering military websites scrubbed of content framed as promoting diversity, equity, and inclusion. An Army spokesperson said the material was "temporarily unpublished" pending review; it remained unavailable as of July 2026.
Interior Secretary Burgum ordered National Park Service to review and remove public content deemed to disparage Americans
On May 20, 2025, Interior Secretary Doug Burgum issued Secretary's Order 3431, implementing President Trump's Executive Order 14253 and directing the National Park Service and other Interior land-management bureaus to review all public-facing interpretive content and remove anything that "inappropriately disparages Americans" or, for natural features, emphasizes matters unrelated to their beauty and grandeur. Under the order, the Park Service removed or flagged signs, exhibits, and materials on slavery, immigration, and climate change at sites nationwide, with an initial content-removal deadline of September 17, 2025. Interior also posted signage inviting visitors to report content they viewed as negative about past or living Americans.

Florida Department of Education pressured science-textbook publishers to soften or remove climate-change content for 2024 state approval
During Florida's 2024 science-textbook review cycle, the Florida Department of Education directed three publishers -- Savvas Learning, McGraw Hill, and Cengage -- to soften or remove accurate climate-change content from science textbooks as a condition of state approval, including replacing a mortality statistic with vaguer language and cutting references to renewable energy and legislative climate action. A July 2, 2024 email from a McGraw Hill vice president to FDOE's instructional materials office documents the specific changes department officials requested. Textbooks touching climate content were adopted by the state at less than half the rate of other science subjects reviewed that cycle.
