The Trump administration told the Smithsonian Institution it's launching a "comprehensive internal review" of the world's largest museum and research complex, per a letter the White House released Tuesday.

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.
