Trump-endorsed Marty O’Donnell won the GOP primary Tuesday to take on Democratic Rep. Susie Lee in Nevada’s battleground 3rd District.
The seat, which touches parts of Las Vegas, is one of Republicans’ targeted pickups this November since President Donald Trump carried it by less than 1 percentage point in 2024 after losing it by nearly seven points in 2020.
But O’Donnell — who also has the backing of the National Republican Congressional Committee — will face an uphill battle. He recently came under fire for hosting a neo-Nazi influencer on his podcast. Trump’s tariffs have hit the district hard, with Canadian tourism to Sin City down by 17 percent, leaving Democrats confident they can hold the seat.
O’Donnell is best known for his role as the audio composer for the “Halo” video game series. It’s his second run in the district after placing fourth in the 2024 Republican primary.
O’Donnell bested several candidates Tuesday, with businessperson Tera Anderson and former Ambassador to Iceland Jeff Gunter — who ran for Senate in 2024 — putting up the most significant challenges.
