H.R. 10475, the Protecting Our History Act of 2026, establishes protections for the Smithsonian Institution's National Museum of African American History and Culture against federal interference with its collections, exhibitions, and scholarly work. The bill prohibits federal officers from restricting, altering, or removing historically documented information about African American history and allows the museum's Board of Regents to transfer at-risk materials to partner institutions or digital archives if federal action threatens the museum's holdings. The legislation reinforces the curatorial and scholarly independence of the Smithsonian from executive interference while preserving all existing legal protections under civil rights laws and other federal statutes. The bill creates new legal remedies that allow plaintiffs to pursue claims without first going through administrative procedures, ensuring swift legal action if federal officials attempt to alter or restrict historical materials.
