Sean Duffy is an American lawyer, former Wisconsin congressman and television personality who became secretary of Transportation in January 2025.

Wisconsin law and congressional career

Raised in Hayward, Wisconsin, Duffy became Ashland County district attorney in 2002 after legal work as a prosecutor. He represented Wisconsin’s 7th congressional district in the U.S. House from 2011 until 2019, serving on the House Financial Services Committee and working on Puerto Rico financial oversight legislation.

Media and family

Before politics, Duffy appeared on MTV reality television, where he met Rachel Campos, later his wife. After leaving Congress, he co-hosted a Fox Business program with Dagen McDowell. Television employment is not evidence of editorial or financial control by other hosts.

Transportation and temporary NASA service

The Senate confirmed Duffy as transportation secretary on January 28, 2025. He temporarily served as acting NASA administrator between July 9 and December 17, 2025, according to NASA’s historical roster; descriptions of that temporary position should not imply he still holds it in November 2026.
