President Donald Trump has endorsed U.S. Rep. Tom Tiffany, R-Minocqua, in his bid to be the next governor of Wisconsin.

Trump announced the endorsement Tuesday night, writing on his social media platform Truth Social that Tiffany had his “Complete and Total Endorsement.”

“He will fight to advance Common Sense Values, and put WISCONSIN, AND AMERICA, FIRST,” Trump wrote.

The endorsement puts to bed the questions of whether — and when — Trump would weigh in on the GOP primary for governor.

Tiffany, who has represented northern Wisconsin’s 7th District in Congress since 2020, was considered an early favorite to clinch the Republican nomination against Washington County Executive Josh Schoemann, but recent fundraising numbers suggested Schoemann could put up a fight.

The backing from Trump has proven critical in Republican primaries across the country, and it’s almost certain to give Tiffany a boost. Four years ago, Trump’s endorsement helped propel businessman Tim Michels over former Lt. Gov. Rebecca Kleefisch in the 2022 GOP primary for governor.

But whether the president’s nod is a help or a hindrance in the general election is an open question, especially in a cycle that polling suggests could favor Democrats. Four years ago, Michels lost to Democratic Gov. Tony Evers in the general election. And almost immediately after Trump’s endorsement Tuesday, the Democratic Party of Wisconsin looked to seize on the president’s support of Tiffany as a condemnation.

“We agree with Donald Trump—Tom Tiffany has been by his side for all of it: ICE murdering Americans in the streets, the Big Ugly Bill, ending funding for the Affordable Care Act, invading Greenland, and raising every day costs,” read a statement from state Democratic Party Chair Devin Remiker. “Donald Trump just made Tom Tiffany the general election nominee, and we will stop him from bringing his chaotic and dangerous agenda in November.”

At least seven candidates are running in the Democratic primary for governor, where many of them have made attacking Trump central to their campaigns. The winner of the general election will replace Evers, who is not seeking a third term.

Trump’s announcement came as part of a slate of endorsements posted to his Truth Social platform late Tuesday evening. He also endorsed Michael Alfonso, who is running for Tiffany’s soon-to-be-vacant seat in Congress.

Alfonso is the 25-year-old son-in-law of U.S. Treasury Secretary Sean Duffy, who represented the 7th District before Tiffany. He’s one of four Republicans running to replace Tiffany.

Trump called Alfonso “a young ‘STAR’.”

In a post on X, Alfonso wrote that it is his “greatest honor to accept this endorsement from President Donald J. Trump,” and pledged “to be a steadfast MAGA warrior.”
