At America’s national parks in the Trump era, the arc of history bends toward revisionism

ASSOCIATED PRESS • October 5, 2025

As part of a broad Trump directive, the National Park Service is under orders to review interpretive materials at all its historical properties and remove or alter descriptions that “inappropriately disparage Americans past or living” or otherwise sully the American story. This comes as the Republican president has complained about institutions that go too deep, in his view, on “how bad slavery was.” The Interior Department order covers more than history. At the nature parks, material that “emphasizes matters unrelated to the beauty, abundance, or grandeur” also is to be flagged. That means references to climate change or other human degradations of nature. At Acadia National Park in Maine, 10 signs citing climate change are now gone. “Our national parks are not billboards for propaganda,” Rep. Chellie Pingree told Interior Secretary Doug Burgum.
