Sean Duffy

Early life and education (1971–1997)

Sean Patrick Duffy was born on October 3, 1971, in Hayward, Wisconsin. Duffy was the tenth child of Tom and Carol Duffy. He was raised in an Irish American Catholic family, several members of which participated in and won Hayward's annual Lumberjack World Championships. Duffy, inspired by his siblings, began logrolling when he was five. He began speed climbing when he was fifteen. Duffy continued lumberjacking after high school, winning a tree climbing title at the 1993 Mississippi River Log Boom. His speed climbing technique involved reckless movement; Fred Scheer compared Duffy to a "race-car driver who bumps the wall now and then". Duffy was the world champion speed climber at the 1994 Lumberjack World Championship.

He graduated from Saint Mary's University of Minnesota with a B.A degree in marketing in 1994 and worked for Scheer's Lumberjack Shows in the summers. By June 1997, The New York Times Magazine considered Duffy one of the top American lumberjacks at that time. Duffy's nephew is Erik Johnson, the longtime Colorado Avalanche defenseman who was the first overall pick in the 2006 NHL entry draft.

Career

Television and sports work (1997–2004)

In 1997, Duffy auditioned for The Real World: Boston, the sixth iteration of MTV's The Real World set in Boston, Massachusetts, and became a cast member by July. In his audition, Duffy said that he was interested in "cute girls"; his role on the show was described by The New York Times as a "resident playboy". On the set of Road Rules, he met Rachel Campos. The two married in April 1999 at the Newman Center at Arizona State University located within Old St. Mary's Church; though they planned to wed later that year, Campos's unexpected pregnancy expedited their wedding. The two have nine children together. He was named as the honorary athlete for the 2004 Badger State Winter Games. Duffy competed in the speed climbing competition for the Great Outdoor Games in 2005.

Prosecutor and district attorney (2002–2010)

After graduating from law school in 1999, Duffy worked for his father's practice for two years before becoming a special prosecutor for Ashland County. He ran unopposed in that year's election and the 2004 election. Duffy served as a Wisconsin delegate in the 2004 Republican National Convention and the 2004 presidential election. In May 2005, Wisconsin's Federal Nominating Commission forwarded four candidates, including Duffy, to succeed J. B. Van Hollen as the United States attorney for the Western District of Wisconsin. Duffy was re-elected in 2006 and 2008. As district attorney, he had a ninety percent conviction rate.

U.S. House of Representatives (2011–2019)

Tenure

In June 2003, Duffy stated that he was considering challenging representative Dave Obey, who had served as the United States representative for Wisconsin's seventh congressional district since 1969, as a Republican in the 2004 election. In July 2009, Duffy indicated he would run for representative. On July 9, at Wausau Homes in Rothschild, Duffy announced that he would challenge Obey in the 2010 election. He later told The New York Times that he decided to challenge Obey, then the chair of the House Committee on Appropriations, over his position in strengthening government, particularly his role in the American Recovery and Reinvestment Act and healthcare reforms proposed during the Obama administration.

Finance filings released by Duffy's campaign in October revealed that he had accrued relatively fewer donations than Obey, though Duffy had not taken money from political action committees. The achievement made the campaign eligible for the National Republican Congressional Committee's Young Guns program, giving it further funding. The Duffy campaign hit in January 2010, setting a record. and the Seventh Congressional District Republican Party through a caucus it held. In May 2010, Obey announced that he would not be running for re-election. The following day, the Duffy campaign was promoted within the Young Guns program, further unlocking additional financial resources. By that month, Duffy had been expected to advance to the general election. In September, Duffy defeated Dan Mielke in the Republican primary. Duffy defeated Julie Lassa to win the general election in November.

Duffy spoke at the 2011 Conservative Political Action Conference, focusing his talk on "cutting spending by the spenders". He criticized earmarks in his campaign, though he later expressed a willingness to secure necessary financing. His critics labeled a measure to construct the St. Croix Crossing as an earmark; Duffy disputed that label. Duffy expressed reservations over an effort to repeal sections of the Affordable Care Act, but voted with Republicans amid a reassurance of a replacement from House majority whip Kevin McCarthy. He voted against a bill that would defund NPR, citing his constituent's use of public radio. In June 2011, the Wisconsin State Assembly approved a congressional map that would politically benefit Duffy with the intention of securing his seat. He was re-elected in 2012, Representatives elections in Wisconsin#District 7|2016]], and 2018.

After being initially sworn in, Duffy was named to the House Committee on Financial Services. In November 2014, he was named as the chairman of the Financial Services Subcommittee on Oversight and Investigations. In October 2015, Duffy was named to the House Select Investigative Panel on Planned Parenthood. A proposed bill by Duffy in July 2011 would have installed a five-member oversight panel to control the Consumer Financial Protection Bureau and would have given Congress greater authority to overturn the bureau's regulations. He praised the Budget Control Act to resolve the 2011 debt-ceiling crisis as an act of bipartisanship. In April 2016, he introduced the Puerto Rico Oversight, Management, and Economic Stability Act to resolve the Puerto Rican government-debt crisis. Duffy proposed a bill in January 2019 that would have expanded presidential tariff authority. Duffy spoke at the 2012 Republican National Convention—despite an overall lessened prominence from House Republicans at the convention that year, the 2016 Republican National Convention, and the 2020 Republican National Convention. Duffy started Plaidcast (2017–2019) in 2017, among several members of Congress who started a podcast that year.

Resignation

On August 26, 2019, Duffy announced that he would resign over complications involving his ninth child, who had not been born yet. His resignation was effective on September 23. Rachel Campos-Duffy gave birth in October. Campos-Duffy stated that the child had "two holes in the heart and valves that need to be fixed", as well as Down syndrome. Duffy's resignation led to a special election; Republican Tom Tiffany won the election, defeating Democrat Tricia Zunker.

Post-government activities (2019–2024)

In October 2019, CNN hired Duffy as a paid contributor. He faced criticism for defending Donald Trump in a scandal involving a quid pro quo with Ukrainian president Volodymyr Zelenskyy and suggesting that a Democratic National Committee server had gone missing in Ukraine. Jeffrey Toobin, a legal contributor to the network, rebuked Duffy for his "anti-immigrant bigotry" after he described the whistleblower Alexander Vindman as loyal to Ukraine. CNN's vice president, Rebecca Kutler, defended Duffy. In November, he joined BGR Group as a senior counsel leading its financial services practice. He was registered to lobby until 2023, when he joined the firm's advisory board, remaining on the board until he was named as Trump's secretary of transportation. Duffy represented various clients, including Enterprise Products and the Partnership for Fair and Open Skies. In 2021, Duffy and his wife, Rachel Campos-Duffy, began a podcast, From the Kitchen Table: The Duffys (2021–2024).

In August 2021, the Duffys purchased a home in Far Hills, New Jersey under a principal residence mortgage and subsequently purchased a second home in Washington, D.C. under a principal residence mortgage in February 2025.

Secretary of Transportation (2025–present)

Nomination and confirmation

On November 18, 2024, President-elect Donald Trump announced his intention to nominate Duffy for U.S. Secretary of Transportation. Duffy appeared before the Senate Committee on Commerce, Science, and Transportation on January 15 in a notably non-contentious hearing that focused on aviation safety and infrastructure. Duffy stated before the committee that he would clear bureaucratic efforts to advance critical infrastructure projects and that he would increase the number of air traffic controllers. The Committee on Commerce, Science, and Transportation voted to advance his nomination 28–0 on January 22.

The U.S. Senate voted to confirm Duffy on January 28, 2025 in a 77–22 vote; protesting a federal grant pause, several Democrats voted against Duffy. Duffy was sworn into office that same day by Supreme Court justice Clarence Thomas.

Tenure (2025–present)

In one of his initial acts as secretary, Duffy moved to revert corporate average fuel economy standards set by his predecessor, Pete Buttigieg. He issued a directive prioritizing high-birthrate areas—predominantly Republican states—for federal assistance and additionally sought to restrict transportation funding from local governments that do not comply with Trump's immigration policy. The following day, a passenger jet collided with a United States Army helicopter over the Potomac River in Duffy's first crisis. In the aftermath of the incident, Duffy directed the Federal Aviation Administration to restrict two helicopter routes near Ronald Reagan Washington National Airport. Following the incident, he repeated Trump's assertion that the apparent failure of air traffic controllers to avert the collision was a result of diversity, equity, and inclusion hiring practices. Days later, the Federal Aviation Administration's NOTAM systems experienced a temporary outage, leading to flight delays. The effort to keep air traffic controllers came with a pay increase. Additionally, Duffy continued the Department of Transportation's oversight of Boeing.

Duffy's work intersected with the Department of Government Efficiency and Elon Musk's activities within the federal government, including efforts to force federal employees to resign. He rejected the Office of Personnel Management's early retirement offer for "critical positions in regard to safety", including air traffic controllers. After Musk stated that the Department of Government Efficiency would assess outdated aviation technology, Duffy confirmed that he had agreed to improve internal systems. Senator Maria Cantwell, the ranking member of the Senate Committee on Commerce, Science, and Transportation, sent a letter to Duffy in response that urged him to dissociate Musk with the Federal Aviation Administration; in February, Duffy said on X that SpaceX officials would be visiting the agency. The following month, The New York Times reported on a meeting between Duffy and Musk in which Duffy criticized the Department of Government Efficiency for purportedly attempting to fire air traffic controllers.

In February, Duffy sent a letter to New York governor Kathy Hochul objecting to congestion pricing in New York City and stating his intention to revoke the program's federal approval. His campaign to end the program involved a social media video featuring five men displeased with congestion pricing. Duffy later delayed New York's deadline to end the program hours before it was originally set. By April, the U.S. Department of Transportation had begun put pressure New York to end congestion pricing after an agreement with New York transit officials stayed the program. That month, Duffy announced that the federal government would assume control of Pennsylvania Station. In addition, he threatened to withhold federal funding from the Metropolitan Transportation Authority over subway crime, risking the city's billion effort to improve transit that depends on federal assistance.{ Duffy cut federal funding for the Texas Central Railway in April and California High-Speed Rail in June.

On May 2, Duffy eliminated $54 million in university research grants that he considered "woke" and "wasteful and divisive." On July 1, 2025, Duffy directed state governors to remove non-standard and distracting road markings from roadways, intersections, and crosswalks. Duffy stated that road markings must be standardized for safety and should not be used for political or artistic messaging. He issued the directive under the Federal Highway Administration's "SAFE ROADS" initiative, which focuses on reducing traffic fatalities on arterial roads.

On July 9, 2025, President Trump named Duffy as the acting administrator of NASA, succeeding acting administrator Janet Petro. He served in the role until Jared Isaacman was sworn in on December 18, 2025.

Political positions

Domestic issues

Duffy has rejected being a member of the Tea Party movement, though he has praised the movement and an associated figure, the conservative political commentator Glenn Beck. In an op-ed for The Washington Times a year after the passage of the Dodd–Frank Wall Street Reform and Consumer Protection Act, he critically reviewed its impact as "woefully under-delivered". Duffy has criticized the federal government's response to climate change as an "agenda of control" and has questioned the scientific consensus of climate change.

In September 2025, Duffy publicly blamed Charlotte city officials for the killing of Iryna Zarutska.

Aviation policy

At the Paris Air Show in June 2025, Duffy advocated for free trade in aerospace.
