Through its 21 museums, 21 libraries, 14 education and research centers and a zoo, the Smithsonian Institution’s collections are expansive and cover every aspect of U.S. history, including more than 200 years of slavery.

CBS host Tony Dokoupil agreed with Trump's criticism of Smithsonian museums focusing too much on America's negative history rather than celebrating achievements.

In April, the National Museum of African American History and Culture sparked controversy after it announced it would return several artifacts to their donors, including a Bible carried during a civil rights protest and Harriet Tubman’s book of hymns, NBC News reported.

President Donald Trump attacked the Smithsonian in a Truth Social post again over its depictions of slavery, receiving heavy pushback online.
