Michael Alfonso, a 26-year-old political novice running in Wisconsin's 7th Congressional District Republican primary, has received campaign contributions from transportation industry lobbyists whose interests fall under the jurisdiction of his father-in-law, U.S. Transportation Secretary Sean Duffy.
The contributions include $2,500 from lobbyists with an interest in the Hudson Tunnel Project, a $16 billion infrastructure undertaking to improve passenger rail service between Manhattan and New Jersey. The White House froze federal grant funding for the project in the fall, citing concerns about diversity and equity measures. Alfonso has no direct influence over the tunnel project.
Alfonso, who has worked in construction and podcasting, has been endorsed by President Donald Trump. He is running to replace Tom Tiffany, who is vacating the seat to run for Wisconsin governor. Duffy held the 7th Congressional District seat for nearly a decade before resigning in 2019.
What the Left Is Saying
Progressives and good-government advocates say the donations illustrate a concerning pattern in which Cabinet secretaries' family members can attract contributions from industries seeking favor without obvious legal violations.
"The law, as it stands, provides very little constraint," said Daniel Weiner, director of the Elections and Government Program at the Brennan Center for Justice. "There's a very large gulf between what is legal and what is ethical. Obviously, this raises numerous ethical questions."
Critics note that many of Alfonso's donors with transportation interests had never contributed to Duffy or Tiffany, suggesting their motivation may be connected to Duffy's current position. The appearance of potential conflicts has drawn comparisons to previous ethical controversies involving Cabinet secretaries.
During the first Trump administration, Transportation Secretary Elaine Chao faced scrutiny for appearing to give preferential treatment to Kentucky officials for millions of dollars in infrastructure grants. Kentucky is the home state of her husband, Mitch McConnell, then Senate majority leader. At the time, Chao's office denied showing any favoritism.
Under President Barack Obama in 2012, Agriculture Secretary Tom Vilsack faced questions about the separation between USDA business and his wife Christie's congressional campaign, though Christie Vilsack said her husband was careful not to be involved in fundraising.
What the Right Is Saying
Supporters argue that Duffy's campaign activity for his son-in-law is entirely legal and does not involve any misuse of government resources or official authority.
A spokesperson for Duffy, Nathaniel Sizemore, provided a written statement saying: "The Secretary attends fundraising events in his personal capacity. Regulatory decisions are guided by career safety professionals, the law, and the facts."
Nothing in current law bars Duffy from campaigning for his son-in-law, provided he does so on personal time, does not use government resources, and does not promise official action in exchange for contributions. The December fundraiser even included a caveat noting that "Sean Duffy is not soliciting funds in connection with this event."
Some Wisconsin Republicans have expressed frustration with Alfonso's candidacy, viewing his familial connections as an unfair advantage in winning a seat they consider important. However, Trump's endorsement has provided significant momentum to the campaign.
What the Numbers Show
As of the end of 2025, Alfonso's campaign had raised a little over $305,000, according to the latest Federal Election Commission filing available.
Contribution limits for each election are $3,500 from individuals and $5,000 from political action committees. Donors can contribute to both primary and general elections simultaneously.
Among Alfonso's donors is Jeffrey Miller, a finance chair of Trump's most recent inaugural committee. The December fundraiser was sponsored by the political action committee for Delta Air Lines.
Alfonso's campaign has received support from a super PAC called Northwoods Future PAC, which is funded with $1 million from Duffy's former campaign committee. Alfonso uses the same fundraising consultant, Kirstin Hopkins, that Duffy employed.
The Bottom Line
The contributions from transportation industry lobbyists to Alfonso's campaign are legal but have raised questions about the intersection of family connections and influence in federal policy. While no laws appear to have been broken, ethics experts say the situation highlights gaps between legal standards and broader ethical expectations.
Duffy has been openly assisting his campaign, appearing as a special guest at November and December events. The outcome of the Republican primary could determine who represents Wisconsin's 7th Congressional District, a seat that has shifted between representatives in recent years.
Voters in the district will ultimately decide whether Alfonso's connections prove advantageous or problematic in their choice of representative. The broader debate over campaign finance ethics and family influence in Cabinet positions is likely to continue regardless of the election outcome.
