Still Seated

Sean Duffy is the 20th Secretary of Transportation and a former congressman and cable-news personality who brought Trump-friendly TV energy into a cabinet post. The Transportation Department says he was sworn in on January 28, 2025, and the department’s current leadership page also says that since July 9, 2025 he has additionally served as acting administrator of NASA. His controversy profile comes from the same mix that made him famous in the first place: Fox-ready culture-war politics, partisan messaging, and the administration’s push to turn even transportation and infrastructure into another theater for ideological combat.
