The president signed an executive order this year ordering the removal of "improper ideology" from the museum system.

In a letter addressed to Lonnie G. Bunch III, the Secretary of the Smithsonian, White House officials said they would lead a “comprehensive internal review” of Smithsonian museums and exhibitions, focusing on areas including public-facing content, the curatorial process, and exhibition planning, among others.

The administration wants the museum system to “celebrate American exceptionalism” and “remove divisive or partisan narratives” ahead of the country’s 250th anniversary.
