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

WASHINGTON (AP) — The White House is ordering a wide-ranging review of the Smithsonian museums and exhibitions ahead of the country’s 250th birthday with a goal of aligning the institution’s content with President Donald Trump’s interpretation of American history.

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.
