Coalition Sues to Block Removal of History, Science Displays from US National Parks

Lawsuit alleges Interior Department order violates federal laws governing National Park Service

Published on Feb. 20, 2026

A coalition of six conservation and education organizations has sued the US Department of the Interior, challenging a policy that has led to the removal of exhibits about slavery, climate change, and Indigenous history from national parks across the country. The lawsuit alleges that the Interior Department's order, issued in 2025, violated multiple federal statutes and was arbitrary and capricious.

Why it matters

The National Park Service manages over 430 sites across the United States, serving as the country's primary public vehicle for preserving and interpreting American history and natural heritage. The removal of these educational displays has raised concerns about the whitewashing of history and science in national parks.

The details

In March 2025, former President Trump signed an executive order titled 'Restoring Truth and Sanity to American History,' directing the Interior Department to ensure that displays at federal sites do not 'inappropriately disparage Americans past or living' and instead emphasize national achievements and the 'beauty, abundance, and grandeur' of natural landscapes. Interior Secretary Doug Burgum then issued an order in May 2025 setting timelines for park staff to review and remove any noncompliant interpretive materials.

The takeaway

This case highlights the ongoing debate over how to accurately and inclusively present American history and science in the nation's public lands and landmarks, with concerns that the current administration's policies are prioritizing a selective, nationalist narrative over a more comprehensive and nuanced understanding of the past and present.
