Smithsonian Secretary Lonnie Bunch announced in September 2026 that he will step down from his leadership role by December 31, 2026. This announcement follows reports of the Trump administration pressuring the Smithsonian to change historical exhibits.
Why it matters
The administration is pushing for a more patriotic version of American history by threatening to cut federal support for the institution. These pressures include requests for exhibit changes, signage updates, and the installation of a George Washington statue.
The Smithsonian is overseen by three federal branches. The institution faces direct administrative orders to alter signage and remove modernist art at the National Museum of American History.
