PHILADELPHIA (AP) — The National Park Service has removed an exhibit on slavery at Philadelphia’s Independence National Historical Park in response to President Donald Trump’s executive order 'restoring truth and sanity to American history' in displays at the nation’s museums, parks, and landmarks. Crews on Thursday removed the exhibit at the President’s House Site, which included the names and other biographical details about the nine enslaved people who lived and worked there under President George Washington. Informational panels had discussed Washington’s use of slave labor at the presidential mansion in Philadelphia, saying he 'knew and trusted' the people he enslaved. Seeking to stop the permanent removal of the panels, the city of Philadelphia on Thursday sued the Department of the Interior and its Secretary Doug Burgum, as well as acting National Parks Service Director Jessica Bowron. Last year, Trump ordered a review of all interpretive materials at National Park Service sites 'to ensure accuracy, honesty, and alignment with shared national values,' as stated by Interior Department spokesperson Elizabeth Peace. The removals have been criticized as an attempt by the Trump administration to erase parts of American history deemed unflattering. The executive order attributed such a narrative to the Biden administration, claiming they fostered a harmful ideology at historical sites.
