Following Trumps order, Interior Department officials issued policies ordering agency employees to report any information, including signage and gift shop items, that might be out of compliance.Trump officials also launched an effort asking park visitors to report offending material, but they mostly received criticisms of the administration and praise for the parks.

The latest orders include removing information at Harpers Ferry National Historic Park in West Virginia, two people familiar with the matter said, where the abolitionist John Brown led a raid seeking to arm slaves for a revolt. Staff have also been told that information at the Presidents House Site in Philadelphia, where George Washington kept slaves, does not comply with the policy, according to a third inspanidual.

...Separately, Park Service officials have ordered the removal of a photograph illustrating violence against slaves, known as The Scourged Back, at one national park. The photograph, taken in 1863, shows scars on the back of a man probably named Peter Gordon from wounds inflicted by his masters before he escaped slavery.
