President Donald Trump ordered signs to be posted outside the Smithsonian National Museum of American History, warning visitors about exhibits his administration considers “inaccurate.”

The order directs the Interior Department to issue warnings and also tell people where they can find “accurate information about American history.”

The Trump administration has often accused the Smithsonian Institution, the world’s largest research museum, as well as other academic organizations of harboring anti-American bias.

The Smithsonian did not immediately respond to the BBC’s request for comment.

Friday’s order, titled Restoring Trust in the Smithsonian Institution, accuses museum leaders of not doing enough to celebrate America’s founders on the 250th anniversary of the country’s independence, which fell on July 4.

It says the museum’s leadership team “views American history as a ‘primary tool’ for promoting ideas of social justice and the radical transformation of our society.”

An attached statement from the White House, external He also accused the museum of veering “toward extreme political activism, rooted in Marxism, to divide, dishearten and discourage Americans.”

Friday’s executive order does not indicate which sources the White House believes would be best qualified to tell the American story.

Democrats who oversee the Smithsonian quickly condemned the order.

“This EO is a clear political overreach, driven by an ideological agenda to rewrite American history,” Congresswoman Melanie Stansbury, ranking member of the House Administration Committee, wrote in X. “Our Smithsonian institutions belong not to the president, but to the American people and our nation’s history.”

The executive order comes just days after Smithsonian director Anthea Hartig was questioned by Republican lawmakers in two congressional hearings, where the museum was accused of being “infected by a woke ideology that has seeped into public exhibits, educational materials and planning documents.”

Earlier this month, the White House Domestic Policy Council released a scathing report, stating that the museum “erases our heritage.”

Trump has set out to radically reshape American culture, which he says has been contaminated by a “woke” left-wing ideology. He has signed several orders aimed at eliminating the federal government’s diversity, equity and inclusion programs, some of which led to legal challenges.

In March, he issued a separate order against the Smithsonian, directing it to “remove inappropriate, divisive, or anti-American ideology.”

The Smithsonian is largely funded by the federal government. Its museums offer free admission to between 15 and 30 million visitors each year. It operates 21 museums in Washington, Virginia and New York.

They include the National Museum of American History, the National Portrait Gallery, the Museum of American Art, the National Zoo, and more than a dozen others.
