Trump-backed Republican Marty O'Donnell wins Nevada primary for key House seat

Reuters · June 10, 2026

June 9 (Reuters) - Marty O'Donnell, backed by U.S. President ​Donald Trump, won the Republican primary on Tuesday ‌for Nevada’s 3rd Congressional District, a Las Vegas-area battleground that could help decide control of the U.S. House of Representatives in ​November, U.S. media projected.

The seat, held by Democrat ​Susie Lee, is among a handful across the ⁠country expected to be decisive in determining the ​balance of power in Congress, with Republicans currently holding ​a narrow House majority.

The Republican primary featured a competitive, largely self-funded field, including Trump-endorsed video game composer Marty O'Donnell, neurosurgeon Aury Nagy ​and former U.S. Ambassador to Iceland Jeff Gunter. ​A fourth candidate is businesswoman Tera Anderson.

O'Donnell, who loaned his campaign $3 ‌million, ⁠is also backed by House Republicans' campaign arm as a member of its "MAGA Majority" program, which supports candidates in battleground districts. Nagy and Gunter have loaned their ​campaigns $1 million and $750,000, ​respectively.

The Republican ⁠nominee will now challenge Lee or her Democratic rival in a race expected to ​draw national attention and significant campaign spending ​ahead ⁠of November’s elections.

Lee won reelection in 2024 by nearly 3 percentage points even as Trump narrowly carried the district, ⁠underscoring ​its status as a closely divided ​electorate.
