Lonnie Bunch, Secretary of the Smithsonian Institution, announced his retirement effective at year-end. His departure follows sustained criticism from the Trump administration, which alleged the national museums under his leadership portrayed a divisive rather than unifying version of U.S. history.

White House officials voiced concerns over exhibitions and interpretive approaches centered on race, national identity and historical events. Officials said the Smithsonian's approach fostered division rather than unity, particularly regarding American exceptionalism, and emphasized a need for "patriotic education" in public institutions.

Bunch, a respected historian, became the first African American to lead the Smithsonian's 19 museums and nine research centers. He founded the National Museum of African American History and Culture, which opened in 2016. His tenure focused on expanding the narrative of American history to include diverse perspectives and underrepresented voices.

The disputes highlighted a broader cultural debate regarding historical interpretation in public institutions, placing the Smithsonian's academic freedom and curatorial independence at odds with political directives.

The Smithsonian Board of Regents will begin a formal search for Bunch's successor. The Board expects to announce a timeline for the search process in the coming weeks.
