A White House official told NBC News that Trump plans to expand his review of museums beyond the Smithsonian, which is based in Washington, D.C.

Trump’s war on the Smithsonian echoes the fight over its founding Salon.com That’s a version of “Americanism” the president and the MAGA crew treat as un-American. But it is a version that I, and millions of other Americans, are proud to serve.

Presiden Trump said the Smithsonian museums are too fixated on "how bad slavery was" and other negative aspects of United States history.

President Trump is reigniting a debate over how Americans speak about diversity after saying the Smithsonian museums focus on how bad the country is.

Both the American history and air and space museums honor American innovation and achievement. The air and space museum’s most famous exhibits include the Wright Brothers’ airplane, the "Spirit of St. Louis," which Charles Lindbergh flew across the Atlantic, and relics from the many U.S. missions to the moon.

The president made the remarks in a social media post amid a White House review of Smithsonian museums and exhibits.

U.S. President Donald Trump said on Tuesday he asked his attorneys to go through museums in Washington while suggesting he would pressure the Smithsonian Institution like he has attempted to pressure colleges and universities.
