Trump Endorses Transportation Secretary Sean Duffy’s Son-in-Law for Wisconsin Congressional Seat
MADISON, Wis. — In a significant political boost, former President Donald Trump has publicly endorsed Michael Alfonso, son-in-law of Transportation Secretary Sean Duffy, as he campaigns for a seat in the U.S. House of Representatives. Alfonso is running to represent Wisconsin’s 7th Congressional District, a key battleground area with a history of competitive races.
Trump took to his social media platform Truth Social on Tuesday night to announce his endorsement, praising Alfonso’s family background and character. “Michael is the son-in-law of our GREAT Secretary of Transportation, Sean Duffy, and the wonderful Rachel Campos-Duffy, of FoxNews, one of the most popular (and talented!) anchors in all of Television,” Trump wrote. He added, “Michael Alfonso has been a WINNER all of his life, comes from a truly spectacular family, and has my Complete and Total Endorsement to be the next Representative from Wisconsin’s 7th Congressional District — HE WILL NEVER LET YOU DOWN!”
Sean Duffy, who has served as the U.S. Secretary of Transportation since mid-2025, has been a prominent figure in the administration, overseeing national infrastructure and transportation policy. His tenure has included efforts to modernize the nation’s transportation systems, aligning with priorities outlined by the U.S. Department of Transportation. Alfonso’s connection to Duffy adds a notable dimension to his campaign, potentially attracting voters familiar with the secretary’s work.
Michael Alfonso, a pro-Trump conservative and grandson of Cuban refugees, launched his campaign late last year. He has been active in conservative circles, including appearances at events such as Turning Point USA’s AmericaFest conference. Alfonso expressed gratitude for Trump’s endorsement in a post on X, formerly Twitter, calling it “my greatest honor to accept this endorsement from President Donald J. Trump. He is truly the greatest president of our time.”
Wisconsin’s 7th District has been a focal point in recent elections, with shifting voter dynamics and a mix of urban and rural communities. The district’s representation will play a role in shaping policy on issues ranging from agriculture to manufacturing and transportation — sectors vital to Wisconsin’s economy.
Political analysts note that Trump’s endorsement may energize Alfonso’s campaign, particularly among conservative voters who remain loyal to the former president. This aligns with broader trends observed in the 2026 midterm election cycle, where Trump-backed candidates have sought to leverage his influence within the Republican Party. The endorsement also highlights the intertwining of political and family networks in contemporary American politics.
As the campaign progresses, Alfonso will face opponents from both major parties in what is expected to be a closely watched race. The outcome could impact the balance of power in the House of Representatives, where control remains competitive.
