A U.S. appeals court late Friday says the Trump administration can halt work on a National Park Service slavery exhibit in Philadelphia while it appeals a judge's order to reinstall it.

Conservation and historical organizations are suing the Trump administration over National Park Service policies that the groups say erase history and science from America’s national parks.

A federal judge has ordered an exhibit about nine people enslaved by George Washington to be restored at his former home in Philadelphia after President Donald Trump’s administration took it down last month.

More than a decade before he became the country’s first president, George Washington was leading a critical campaign in the early days of the American Revolution.

A federal judge warned Justice Department lawyers that they were making “dangerous" and “horrifying” statements when they said the Trump Administration can decide what part of history to display at National Park Service sites.

Outraged critics are accusing President Donald Trump of “whitewashing history” after the National Park Service removed an exhibit on slavery at Philadelphia’s Independence National Historical Park.
