Marty O’Donnell, a Republican candidate in Nevada’s 3rd Congressional District recently endorsed by President Donald Trump, hosted a Nazi supporter on his podcast last year, months after filing to run for Congress.

O’Donnell is an outsider candidate who also ran in the district in 2024, placing fourth in the GOP primary. He was best known before his political career as the music composer for the “Halo” video game series. 

But with Trump’s endorsement — as well as backing from the National Republican Congressional Committee’s MAGA Majority program — the unlikely political candidate has become the favorite for the nomination, despite facing a former U.S. ambassador to Iceland, among others.

In August 2025, O’Donnell hosted Charles Cornish-Dale, a popular far-right influencer better known by his online pseudonym “Raw Egg Nationalist,” on his podcast for a friendly discussion. Repeatedly, over the course of multiple years, Cornish-Dale has shared antisemitic and pro-Nazi content on his Raw Egg Nationalist X account.

Those posts include a quote from Mein Kampf alongside a meme featuring a man in a Nazi uniform in front of a swastika flag; a reference to the “zog” — a conspiracy theory claiming Zionist control of the U.S. government and society; the shorthand “HH” — which stands for Heil Hitler; an advertisement for “Blood, Soil and Grass-fed Beef” t-shirts — referencing a Nazi and white nationalist slogan; and various other Nazi-sympathetic posts.

In his introduction to the interview, O’Donnell acknowledged that Cornish-Dale has been “accused of many weird — fascist, nationalist, white nationalist, misogynist, you name it — he’s been accused of everything. And of course I’m being accused of those things too, so I had to talk to him to find out what’s true and what’s not true.” He called the interview “one of those sort of marriages made in heaven.”

“Charles Cornish Dale was booked by Marty’s production team. Marty was unfamiliar with Dale before the interview and was unaware of these posts shared by Jewish Insider until we received the inquiry,” Keith Schipper, a spokesperson for O’Donnell, said in a statement. “Marty’s support of Israel is unequivocal and, as seen in various interviews and online posts, he will not tolerate the rise of anti-semitism in our country. Marty will continue to fight bigotry, misinformation, and hate toward Israel because it is the right and moral thing to do.”

Later in the interview, O’Donnell again dismissed criticisms of Cornish-Dale, including accusations of white nationalism and misogyny, as not credible. Cornish-Dale responded, “Once upon a time you were a Nazi if you held specific political beliefs and worshiped Adolf Hitler and all that, and now you’re just a Nazi if you’re right wing” — glossing over his own past commentary.

O’Donnell’s personal Discord server — The Marty Army — which he has used and promoted for campaign purposes, also contains a number of users who have shared antisemitic, pro-Nazi and anti-Israel sentiments, even as O’Donnell himself has personally debated with and threatened to ban some of those users from the server — and appears to have banned at least one such user.

Some of those comments, including a series of comments deriding the Anti-Defamation League, have been shared in a channel dedicated to O’Donnell’s congressional campaign.

O’Donnell’s friendly interview with Cornish-Dale comes in spite of his own personal history of speaking out against antisemitism and in support of Israel on social media, in the Discord server and in other public forums.

In a recent podcast interview, O’Donnell leaned into the religious and historical connection between Jews and Christians, and emphasized the West’s “Judeo-Christian” heritage.

“These Christian weirdos who are heretics, who say, ‘Oh, well, the Jews killed Jesus.’ Like, no, Jesus said, ‘No one takes my life from me. Amen. I lay down willingly. I’m doing my Father’s will.’ This is the plan for saving humanity, and it’s a Judeo-Christian plan. That’s God’s plan. That’s the people He chose,” O’Donnell said.

He said he believes that politics now is a form of “spiritual warfare,” including against antisemitic figures on the far right.

“How else do you explain Candace Owens? How else do you explain Tucker Carlson? Some evil spirit has clouded their minds, whether they’re just grifting for money or something evil is happening, but it’s spiritual warfare,” he said.

“Antisemitism, or Jew Hatred, is NOT ‘woke right’. Groypers, [Nick] Fuentes, and his followers are as far from the right as any of the godless Marxist progressives are,” he said at another point on X last year.

The National Republican Congressional Committee announced on Monday that it’s targeting Rep. Jared Moskowitz’s (D-FL) South Florida district as a potential opportunity to flip a Democratic-held seat in the 2026 midterms, honing in on one of the most heavily Jewish congressional districts in the country.

Moskowitz took office in January 2023 in the district that includes parts of Broward and Palm Beach counties, including some of Fort Lauderdale, Deerfield Beach, Boca Raton, Coral Springs and Parkland. The district, once safely Democratic, has been trending increasingly competitive in recent years, particularly in the wake of the Florida redistricting cycle. The Cook Political Report rates the district “Lean Democrat.”

“Out-of-touch Democrat Jared Moskowitz has repeatedly bent the knee to the most extreme wing of his party instead of putting his constituents — and common sense — first,” NRCC spokesperson Maureen O’Toole said in a statement, pointing to his votes against government funding legislation and a bill banning transgender athletes from participating in women’s sports. “Moskowitz is more interested in getting on TV than delivering for Floridians. With a strong Republican field ready to step up and challenge him, Moskowitz’s days in Congress are numbered.”

The Democratic Congressional Campaign Committee did not respond to a request for comment. Moskowitz was not on the DCCC’s initial list of endangered “frontline” incumbents. 

Moskowitz has cut a unique profile in Congress: he’s often shown a willingness to reach across the aisle in policymaking and has appeared on conservative media, even as he has also enjoyed sparring with Republicans. The former state senator also has bipartisan credentials back home, having been appointed by GOP Gov. Ron DeSantis as the director of emergency management in the state, and later as a Broward County commissioner.

He has frequently worked with Republicans, and broken with many in his own party, on issues related to Israel, Iran and antisemitism, at times criticizing the Biden administration’s actions. Given that pro-Israel policy is a major priority for many voters in the district, it could become a focus on the campaign trail.

Moskowitz was briefly floated as a potential nominee for the Trump administration to lead the Federal Emergency Management Agency, and is seen as having ambitions for a statewide campaign.

Ford O’Connell, a Republican strategist in Florida, said that the district is “a jump ball,” noting that President Donald Trump and Republicans continue to gain ground in the state, but said that “the biggest issue the Republicans are going to have is that Jared is pretty skilled” as a politician. 

National Republicans did not make concerted efforts to flip the seat in the 2022 or 2024 cycles.

O’Connell said that the NRCC’s early campaign will likely be focused on attacking Moskowitz’s image and popularity to make him an easier target, before looking at specific candidates to recruit or back.

“If they can do that successfully and make the case that he’s not a common-sense Democrat but in fact someone who is hook, line and sinker a Democrat, they think that they can probably knock him off,” O’Connell continued.

Former state Rep. George Moraitis, a graduate of the U.S. Naval Academy, is the most prominent Republican to enter the race on the GOP side thus far. Moraitis is centering his campaign on issues including the economy and national security.

Jewish Democratic leaders in the district largely argue that Moskowitz is popular enough locally — particularly when it comes to pro-Israel policy — that he should be relatively safe from a challenge. Moskowitz won reelection in 2024 with 52% of the vote.

But the Republican inroads in the South Florida district are significant: After President Joe Biden won Moskowitz’s district by a comfortable 13-point margin in 2020, Vice President Kamala Harris barely eked by, with less than a two-point margin of victory four years later.

“I think they’ve underestimated Jared before, and they’ll continue to do that again. I’m convinced he’ll win reelection,” Mitch Ceasar, a former chair of the Broward County Democratic Party, told Jewish Insider. “And as to folks who sometimes think he takes an approach that’s not exactly in line with the party — well, he’s voting exactly in line with his district.”

Ceasar argued that, while the margins may be close, Moskowitz is a skilled campaigner and fundraiser and is deeply in tune with his district, making it difficult for Republicans to challenge him.

Former state Rep. Joseph Geller predicted that, in the more favorable environment Democrats are likely to face in 2026, Moskowitz will expand his margin of victory.

“They can make it a fight, [but] I don’t think they’re going to beat Jared,” Geller said. “That is a function of him doing what he needs to do, but I know Jared. He’s got to raise the money, he’s got to run the campaign, he’s got to get his message out, he’s got to have people see him. But he does those things. That’s why he’s in there to begin with.”

“If he does what he needs to do, and I have every reason to think he will, he will win,” Geller reiterated. He also urged progressives in the district not to “let perfect be the enemy of the good, and [Moskowitz] is a good congressman and a good public servant and a good Democrat.”

Ceasar said he did not have hard data on the issue, but speculated that the growing Orthodox Jewish community in the district, particularly in Boca Raton, may be driving some of the rightward shift in the district.

Geller attributed that shift more to trends unfavorable to Democrats nationally and statewide in the past two election cycles, more than any factors specific to the district itself. 

“I think Jared Moskowitz in ‘26 in a better environment does just fine,” Geller said.
