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 After Musk stated that the Department of Government Efficiency would assess outdated aviation technology, Duffy confirmed that he had agreed to improve internal systems.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. astronauts in July 2025 On May 2, Duffy eliminated $54 million in university research grants that he considered "woke" and "wasteful and divisive." 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. On May 2, 2026,
Spirit Airlines announced it would be "shutting down" after talks with the federal government about a "rescue package" bailout of some $500m collapsed. Speaking to reporters, Duffy placed the blame for this development on the refusal, during the
Biden presidency, to allow a merger between Spirit and
JetBlue that would have ostensibly saved Spirit. ==Political positions==
