PHILADELPHIA (AP) — In a move spurred by President Donald Trump’s executive order aiming to “restore truth and sanity to American history,” the National Park Service has dismantled a slavery exhibit at Philadelphia’s Independence National Historical Park.

The removal occurred on Thursday at the President’s House Site, where the exhibit had previously provided details about the nine enslaved individuals who lived and labored there under President George Washington. The display featured panels that not only named these individuals but also offered biographical insights, highlighting Washington’s reliance on enslaved labor at his Philadelphia residence, noting his familiarity and trust in those he enslaved.

In response to the exhibit’s removal, the city of Philadelphia filed a lawsuit on Thursday against the Department of the Interior, its Secretary Doug Burgum, and the acting National Parks Service Director, Jessica Bowron, seeking to prevent the permanent elimination of these informational panels.

Last year, President Trump initiated a review of all interpretive materials at National Park Service locations. This was to ensure their content reflected accuracy, honesty, and alignment with what the administration considers shared national values, according to Interior Department spokesperson Elizabeth Peace, in a statement to The Washington Post.

“After completing the mandated review, the National Park Service is now proceeding to remove or revise interpretive materials as stipulated by the Order,” Peace explained in the statement.

The removals confirmed what critics have long condemned as the Trump administration’s attempt to erase unflattering aspects of American history.

The order, which Trump signed last March, blamed the Biden administration for advancing a “corrosive ideology” at the nation’s historic sites.

“At Independence National Historical Park in Philadelphia, Pennsylvania — where our Nation declared that all men are created equal — the prior administration sponsored training by an organization that advocates dismantling ‘Western foundations’ and ‘interrogating institutional racism’ and pressured National Historical Park rangers that their racial identity should dictate how they convey history to visiting Americans because America is purportedly racist,” the order states.
