President Trump's effort to rewrite the past at the country's museums, parks and landmarks was struck down on Friday, with a federal judge calling for the administration to restore changes already made at locations nationwide.

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 these efforts are meant "to rewrite the Nation's history with a white-out pen."

"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 Trump administration issued an executive order, entitled "Restoring Truth and Sanity to American History," in March 2025 ordering national parks to not display elements that "inappropriately disparage Americans past or living."

However, Kelley countered that Trump's order was just an excuse to erase the true history of the United States.

"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," Kelley wrote.

The Trump administration must also provide a status report every week describing the progress they've made with these changes, the judge wrote. The administration has 21 days to "restore and reinstall all interpretive materials at park sites managed by the NPS that, pursuant to the Secretary's Order, have been altered, removed, or damaged in the process of such removal since May 20, 2025," according to the order. 

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.

Mr. Trump signed the executive order last year and 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."
