A federal judge on Friday ordered the Trump administration to restore sites changed under an executive order calling for the nation’s museums, parks and landmarks to not display elements that “inappropriately disparage Americans past or living.”
The preliminary injunction issued by U.S. District Judge Angel Kelley in Massachusetts also orders a pause on any additional changes, writing that the plaintiffs have shown that these efforts are meant “to rewrite the Nation’s history with a white-out pen.”
“History cannot be faithfully told while excluding the experiences of communities whose contributions, struggles, and achievements form an important part of our Nation’s story,” the judge wrote.
The Trump administration must also provide a status report every week describing the progress they’ve made with these changes, the judge wrote.
“Under the guise of promoting American dignity, this Administration seeks to share a limited history by ordering the removal of all signs, displays, and interpretive exhibits at National Parks that do not align with its preferred narrative, thereby telling half-truths,” Kelley wrote.
The order comes in response to a February lawsuit filed by conservation and historical organizations over National Park Service policies that the groups say have forced park service staff to remove or censor dozens of exhibits that share factually accurate and relevant U.S. history and scientific knowledge, including about slavery and climate change.
Many of the changes were at Philadelphia’s Independence National Historical Park, where the administration removed exhibits on the lives of nine people enslaved at the site in the 1790s under George Washington, the first U.S. president. Other changes included removing a sign at Sunset Crater Volcano National Monument in Arizona describing basalt bubbles because it had an image of a visitor holding a Pride flag while films on labor history were removed from the Lowell National Historical Park in Massachusetts.
President Donald Trump signed the executive order “restoring truth and sanity to American history” at the nation’s museums, parks and landmarks last year. Interior Secretary Doug Burgum later directed removal of “improper partisan ideology” from museums, monuments, landmarks and other public exhibits under federal control.
An email seeking comment from the Interior Department was sent Saturday.
Alan Spears, senior director for cultural resources for the National Parks Conservation Association, one of the organizations that brought the lawsuit, said the ruling will help protect national parks from the administration's effort “to erase history and science at these one-of-a-kind places.”
“National parks belong to the American people and censorship of any kind goes against the values these places represent,” he said.
Bill Wade, executive director for the Association of National Park Rangers, another organization that brought the lawsuit, said this is especially good news for National Parks employees who “have prided themselves for being able to provide truthful, accurate and unbiased information."

A first-of-its-kind law in New York could force 3D printers sold for homes and business to come equipped with technology blocking them from making guns.
The new requirement, also under consideration in California, attempts to thwart the latest technique for producing untraceable “ghost guns” that have turned up in crimes. But there are questions about whether the technology can work and concerns about its effect on personal privacy and constitutional rights.
About one-third of U.S. states already have taken steps to ban or regulate build-it-yourself firearms that lack serial numbers and evade the background checks required to purchase guns from federally licensed dealers. What makes the new effort unique is that it targets the equipment used to produce the firearms, not the people who make them.
The blocking technology being pushed in two of the nation's most populous states has the potential to set industry standards for 3D printers. It also could serve as a model for other Democratic-led states wanting to add to their gun regulations, which often already ban certain semiautomatic weapons and allow firearms to be temporarily confiscated from people deemed to pose a threat to themselves or others.
Three-dimensional printers have become increasingly common over the past couple of decades.
Since 2012, the number of 3D printers worldwide has grown from an estimated 30,000 to over 3 million while the industry's value has multiplied from around $2 billion to $26 billion annually, said Bill Decker, executive chairman of the Association of 3D Printing. Though high-end printers cost thousands of dollars, some 3D printers now can be bought for as little as several hundred dollars.
The devices can make toys, prosthetic limbs and even airplane parts. They also can make firearms — or the pieces necessary to assemble them — using digital designs available online. Homemade guns that lack serial numbers often are called “ghost guns," because they are hard for law enforcement officers to trace.
Firearms made with 3D printers are increasingly being used in crimes, according to a U.S. Department of Justice report released last year. The number of privately made guns recovered in crimes and submitted to federal authorities rose from about 1,600 in 2017 to nearly 27,500 in 2023, though the report didn't specify how many came from 3D printers.
In a high-profile New York case, police say a 3D-printed gun likely was used to kill UnitedHealthcare’s CEO in 2024.
A New York law signed last month and a bill in the California Legislature both would direct panels of experts to come up with standards for firearm blueprint detection algorithms. The technology would analyze every design submitted for 3D printing, compare it to a digital library of firearm parts, and reject those that are similar.
Though the study process would start now, the mandate that 3D printers come equipped with firearm blocking technology wouldn't begin until 2029 — or later, in New York's case, if the study group determines it's not yet feasible.
The concept is a bit like a smartphone app that identifies trees or flowers from an uploaded photo, said Solomon Diamond, an associate engineering professor at Dartmouth College who was among several experts at a recent online seminar about the legislation.
For 3D printers, one possible method could use a geometric analysis of shapes, dimensions and other structural features to reject print projects that closely resemble firearm parts.
"Geometric search is mature, it’s deployed, it is ready to be applied to this problem,” said Julian Chultarsky, a technical account manager at Physna, a Columbus, Ohio-based company that develops such technology.
The Association of 3D Printing supports the legislation in New York and California, but “it's not going to work,” Decker said. "It’s more of a political statement than anything else.”
Criminals still will come up with ways to make guns from 3D printers, either by altering their designs or taking their printing projects elsewhere, Decker said.
The more aggressive the technology becomes, the more likely that it also blocks unintended items, said Rory Mir, director of open access and technology community engagement at the Electronic Frontier Foundation, a nonprofit digital rights group. Some harmless pipes might look like gun parts, or an S-shaped wall hanger might resemble an auto sear trigger used to modify a semiautomatic weapon into a machine gun.
“These sort of censorship algorithms don’t work, and they wind up capturing and blocking a lot of lawful speech," Mir said.
If print instructions are submitted for a cloud-based artificial intelligence search, it also risks the privacy of people's artistic and proprietary creations, Mir said.
Gun safety advocates say 3D printers have created a new pathway for people who cannot legally purchase firearms — like children or convicted felons — to nonetheless obtain them. Eleven states already generally prohibit 3D-printed guns, and six additional states require them to receive serial numbers, according to Everytown for Gun Safety.
Blocking the actual 3D printing of firearms could make it harder for people to ignore such laws.
“3D printing really is the new frontier of the fight against ghost guns,” said Samuel Levy, director of policy advocacy at Everytown for Gun Safety.
The National Rifle Association might partly agree with that assertion, though it disagrees with the policy.
“Despite desperate fear-mongering campaigns, homemade firearms are nothing new — they are a proud, time-honored American tradition dating back to the founding of our Republic," John Commerford, executive director of the NRA Institute for Legislative Action, said in a statement. He added that "these measures only restrict responsible Americans — who do follow the law — from participating in constitutionally protected activities.”
