Sean Patrick Duffy (born October 3, 1971) is an American politician, attorney, and former television personality serving as the 20th United States Secretary of Transportation since January 2025. A member of the Republican Party, Duffy has had an unusually varied career trajectory — from competitive lumberjack and reality television cast member to district attorney, United States congressman, cable news host, and Cabinet secretary. He represented Wisconsin's 7th congressional district in the U.S. House of Representatives from 2011 to 2019, having previously served as the district attorney of Ashland County, Wisconsin, from 2002 to 2010. Duffy resigned from Congress in September 2019 following health complications involving his newborn daughter. After his departure from elected office, he worked as a political lobbyist and later as a co-host on Fox Business Network before being nominated by President Donald Trump to lead the Department of Transportation. He was confirmed by the United States Senate on January 28, 2025, and sworn in the same day. Duffy additionally served as the acting administrator of NASA from July to December 2025.

Early Life

Sean Patrick Duffy was born on October 3, 1971, in Hayward, Wisconsin, a small city in Sawyer County in the northwestern part of the state. Hayward is known as the home of the Lumberjack World Championship, an annual competition that has taken place in the city since 1960. Duffy grew up in this tradition and became a professional lumberjack, competing in the Lumberjack World Championship for several years. He won multiple titles in speed climbing, a discipline in which competitors race to scale tall wooden poles as quickly as possible.

Duffy's lumberjack career connected him to the broader outdoor sporting culture of northern Wisconsin. His competitive background in the sport would later become a frequently noted aspect of his public biography, distinguishing him from most other members of Congress and Cabinet officials.

In 1997, Duffy appeared as a cast member on The Real World: Boston, the sixth season of MTV's pioneering reality television series. The show followed a group of young adults living together in a house in Boston, Massachusetts, and Duffy's appearance introduced him to a national audience years before he entered politics. His reality television background would be revisited by media outlets throughout his subsequent political career.

Education

Duffy attended St. Mary's College of Minnesota, where he earned a degree in marketing. He subsequently enrolled at William Mitchell College of Law in Saint Paul, Minnesota, graduating in 1999 with a Juris Doctor degree. His legal education prepared him for a career in law and public service, and he would go on to pass the bar and practice law in Wisconsin.

Career

District Attorney of Ashland County

In 2002, Duffy was appointed by Wisconsin Governor Scott McCallum as the district attorney of Ashland County, Wisconsin. He succeeded Michael Gableman, who would later serve as a justice on the Wisconsin Supreme Court. As district attorney, Duffy was the chief prosecutor for Ashland County, responsible for overseeing criminal prosecutions and representing the state in legal proceedings within the county.

Duffy served in the position for approximately eight years, from August 1, 2002, until July 9, 2010, when he departed to pursue a seat in the United States Congress. He was succeeded as district attorney by Kelly McKnight.

United States House of Representatives

2010 Election

In July 2009, Duffy announced his candidacy for Wisconsin's 7th congressional district, challenging the long-serving Democratic incumbent Dave Obey, who had represented the district since 1969. The race drew national attention as part of the Republican wave building in the lead-up to the 2010 midterm elections.

In March 2010, Obey announced that he would not seek re-election, fundamentally altering the dynamics of the race. Wisconsin State Senator Julie Lassa won the Democratic nomination to succeed Obey. Duffy defeated Lassa in the November 2010 general election, winning the seat in what was widely considered a Republican-leaning political environment nationally. His victory was part of a broader Republican wave in the 2010 midterm elections that saw the party gain 63 seats in the House of Representatives and reclaim the majority.

Congressional Tenure

Duffy took office on January 3, 2011, representing a large, predominantly rural district in northern and central Wisconsin. The 7th district encompassed much of the northern portion of the state, including areas dependent on agriculture, forestry, and tourism.

During his time in Congress, Duffy served on several committees and was involved in various legislative efforts. In October 2015, he was selected by House Speaker John Boehner to participate in a select committee focused on investigating Planned Parenthood, which was led by Representative Marsha Blackburn.

Duffy was re-elected in the 2012, 2014, 2016, and 2018 election cycles, serving a total of nearly nine years in the House. Over the course of his congressional career, he represented the interests of his largely rural constituency in northern Wisconsin.

Resignation

On September 23, 2019, Duffy resigned from Congress. His departure was prompted by health complications involving his newborn daughter, the ninth child for Duffy and his wife. Duffy had announced his intention to resign in August 2019, citing the need to focus on his family during the medical challenges his daughter faced. He was succeeded in the 7th district by Tom Tiffany, who won a special election to fill the vacancy.

Post-Congressional Career

Lobbying

After leaving Congress, Duffy joined BGR Group, a prominent political lobbying firm based in Washington, D.C. His move to the lobbying sector was reported by Politico in November 2019. The transition from congressional office to lobbying work is common among former members of Congress, though it drew attention given the relatively short time between his departure from the House and his new role.

Duffy's background as a lobbyist was later noted when he was nominated to serve as Secretary of Transportation. Politico reported on his lobbying history at the time of his nomination, noting that Trump had tapped a former lobbyist to lead the Department of Transportation.

CNN Commentary

Duffy also worked as a political commentator for CNN following his departure from Congress. His television appearances occasionally generated controversy; in October 2019, Politico reported on an incident in which Duffy's commentary on immigration issues drew criticism from some observers.

Fox Business Network

In December 2022, Fox Business Network announced that Duffy would join the network as a co-host. Beginning in 2023, he co-hosted The Bottom Line alongside Dagen McDowell. The program covered business news and political developments, and Duffy's role on the show maintained his public profile in the period before his nomination to the Cabinet.

United States Secretary of Transportation

Nomination and Confirmation

On November 18, 2024, President-elect Donald Trump announced his intent to nominate Duffy to serve as the United States Secretary of Transportation. The nomination was part of Trump's broader Cabinet selection process ahead of his second presidential term, which drew significant media attention. The New York Times reported on Duffy's nomination in the context of Trump's broader Cabinet picks, which included several figures who were seen as aligned with Trump's policy priorities.

Duffy was confirmed by the United States Senate on January 28, 2025, and was sworn in as the 20th Secretary of Transportation the same day. He succeeded Pete Buttigieg, who had served in the role during the administration of President Joe Biden. Steven G. Bradbury served as Duffy's deputy secretary at the Department of Transportation.

Tenure

As Secretary of Transportation, Duffy has overseen the Department of Transportation's operations, which encompass federal oversight of aviation, highways, railroads, transit systems, and maritime transportation. His tenure has been marked by a focus on emerging transportation technologies, including autonomous vehicles and advanced air mobility.

In March 2025, Duffy hosted the first-ever National Autonomous Vehicle (AV) Safety Forum, organized in conjunction with the National Highway Traffic Safety Administration (NHTSA). The forum was designed to bring together innovators in the autonomous vehicle space to discuss safety standards and the regulatory framework for AV development in the United States. "We want to make sure that the United States leads the way on safety and on innovation," Duffy stated at the event.

Also in March 2025, Duffy and the Federal Aviation Administration (FAA) announced the selection of eight pilot projects for testing next-generation aircraft, specifically electric vertical takeoff and landing (eVTOL) vehicles, in American airspace. The initiative was part of a broader push to advance advanced air mobility, which encompasses air taxis, medical transport drones, and cargo logistics aircraft. Duffy described the technology as one that would "radically redefine personal travel, regional transportation, cargo logistics" in the United States. The announcement attracted attention from investors, with ARK Invest, led by Cathie Wood, increasing its position in Joby Aviation in connection with the administration's advanced air mobility push.

Duffy has also addressed operational challenges in the nation's transportation infrastructure. In January 2026, following significant winter storm disruptions to air travel, Duffy told CNBC that air travel would return to normal within days, addressing public concern about widespread flight cancellations.

In March 2026, Duffy publicly criticized Senate Minority Leader Chuck Schumer in connection with Transportation Security Administration (TSA) staffing shortages and airport delays, linking the issue to a dispute over Department of Homeland Security funding amid a government shutdown standoff. Duffy called for Schumer to "get off the political bandwagon" and support DHS funding so that TSA workers could be paid.

Duffy's tenure as Secretary of Transportation has also intersected with the broader dynamics of the Trump administration. The New York Times reported in March 2025 on the influence of Elon Musk and the Department of Government Efficiency (DOGE) within the administration, a context in which Cabinet secretaries like Duffy operated.

Acting NASA Administrator

On July 9, 2025, President Trump announced that Duffy would serve as the acting administrator of NASA, in addition to his duties as Secretary of Transportation. He succeeded Janet Petro, who had been serving in an acting capacity. Duffy held the NASA role until December 18, 2025, when the Senate confirmed Jared Isaacman as the permanent administrator of the space agency. Duffy's dual role was unusual, as the Secretary of Transportation and the head of NASA typically operate as separate positions with distinct portfolios, though both agencies deal with aspects of aerospace and aviation policy.

Personal Life

Duffy is married to Rachel Campos-Duffy, a television personality and Fox News host who also appeared on MTV's The Real World franchise. The couple met through their connections to the reality television series. Rachel Campos-Duffy's sister, Leah Campos, is Duffy's sister-in-law, and his nephew is Erik Johnson.

Duffy and his wife have nine children together. In August 2019, Duffy announced his resignation from Congress, citing health complications involving his ninth child, who was expected to be born with a heart condition and Down syndrome. Duffy stated at the time that he needed to devote his attention to his family during the medical challenges ahead.

The family has resided in Wisconsin and in the Washington, D.C., area during Duffy's periods of government service.

Recognition

Duffy's career has spanned multiple fields, and he has received attention for the unusual breadth of his professional background. His competitive lumberjack career, in which he won multiple Lumberjack World Championship titles in speed climbing, made him one of the most unconventional members of Congress during his House tenure.

His appearance on The Real World: Boston in 1997 made him one of a small number of former reality television personalities to later serve in the United States Congress or in a presidential Cabinet. The New York Times explored Duffy's reality television background in a June 2025 article examining the intersection of entertainment media and political careers.

As Secretary of Transportation, Duffy has been profiled by major news outlets and has appeared on numerous television programs discussing transportation policy, including appearances on CNBC, Fox Business, and C-SPAN.
