President Donald Trump has entered the fray in Nevada’s battleground congressional races, announcing his support for two Republican challengers seeking to flip key seats in the Silver State. The endorsements target the 1st and 3rd Congressional Districts, areas seen as critical to the GOP’s efforts to regain or maintain a House majority.
In a series of Tuesday afternoon posts on Truth Social, Trump threw his weight behind video game composer Marty O’Donnell and state Sen. Carrie Buck. The moves signal a strategic effort to consolidate the Republican base ahead of the primary elections and set the stage for general election clashes against Democratic incumbents in Las Vegas and the surrounding suburbs.
The endorsements come as a catalyst for both candidates, providing a high-profile seal of approval that often translates into increased fundraising and voter turnout in primary contests. Trump linked both candidates to his “America First” agenda, specifically highlighting a commitment to cutting taxes and regulations, securing the U.S. Border, and advancing domestic manufacturing.
Central to the president’s pitch is a specific economic proposal: “NO TAX ON TIPS.” Trump used his social media platform to criticize the Democratic incumbents in these districts, alleging they have voted against this policy, which he intends to promote further during a scheduled trip to Las Vegas this Thursday.
The Battle for the 3rd District: O’Donnell’s Path
In the 3rd Congressional District, Marty O’Donnell is now positioned as the front-runner for the GOP nomination. The district is one of the most competitive in the country, stretching from southwestern Las Vegas to the southern tip of Nevada. O’Donnell is seeking to unseat four-term Rep. Susie Lee (D-NV).
The endorsement is a pivotal moment for O’Donnell, who has a complicated history with the former president. Having previously faced criticism from within his own party for past remarks about Trump, O’Donnell had essentially tied his candidacy to this moment, stating he would drop out of the race if he did not receive the president’s backing.
O’Donnell’s ascent is not without hurdles. He placed fourth in the GOP primary for this same seat in 2024. However, the current endorsement follows a recent boost from Gov. Joe Lombardo (R), creating a powerful alignment of state and national Republican leadership behind his campaign.
“I am beyond grateful that President Trump has picked me for his team and given me his endorsement today,” O’Donnell said in a Tuesday statement. He called on other Republicans to “unite around the President and me to help us save our majority.”
O’Donnell faces a crowded primary field, including former Ambassador to Iceland Jeff Gunter, Dr. Aury Nagy, and 2024 Las Vegas mayoral candidate Tera Anderson. While O’Donnell is expected to attend Trump’s Las Vegas event this week, he will not be a formal part of the programming.
Carrie Buck and the Fight for the 1st District
In the 1st Congressional District, which encompasses the urban core of Las Vegas, Henderson, and Boulder City, State Senator Carrie Buck (R-Henderson) has secured Trump’s “Complete and Total Endorsement.” Buck is challenging Rep. Dina Titus (D-NV).
Trump praised Buck as “a Successful School Principal and Civic Leader,” emphasizing her professional background in education. Buck has already established a strong financial foundation for her campaign, with fundraising numbers that have reportedly outperformed those of the incumbent.
Buck’s platform focuses heavily on the cost of living and border security. In a statement shared with the press, she argued that Rep. Titus has “lost touch with Nevadans,” claiming the incumbent voted to raise taxes while families struggle with inflation.
“I’m honored to have earned President Trump’s endorsement,” Buck stated. “Dina Titus has lost touch with Nevadans. While families here struggle with rising costs, Titus voted to raise our taxes, and fought to keep our borders open. We deserve better.”
Buck is expected to have a more prominent role in the upcoming visit than O’Donnell, with plans to attend Trump’s Thursday roundtable in Las Vegas.

Strategic Implications and the ‘Trump Effect’
The impact of these endorsements is often measured by primary victory rates. Historical data from 2022 indicates that a vast majority of Trump’s endorsed candidates won their primaries, though that figure is nuanced by the fact that he frequently backed incumbents or candidates who were running unopposed according to NPR reporting.
By aligning O’Donnell and Buck with the “no tax on tips” policy, Trump is attempting to pivot the GOP toward a populist economic message that appeals to the high concentration of service workers in the Las Vegas valley. This strategy aims to peel away traditional Democratic voting blocs in the hospitality and tourism sectors.
For the candidates, the endorsement serves as a firewall against primary challengers. In the 1st District, Buck faces opponents including retired teacher and pastor Jim Blockey and an indicted real estate investor. In the 3rd, O’Donnell’s shift from a fourth-place finish in 2024 to the current front-runner status underscores the volatility and influence of the president’s support within the GOP primary process.
The next critical checkpoint for these campaigns is Trump’s Thursday visit to Las Vegas, where the “no tax on tips” policy will be the centerpiece of the event. This visit will serve as the first major public appearance for the candidates alongside the president, providing a litmus test for their ability to mobilize the “America First” base in Nevada.
