Sen. Mark Kelly, D-Ariz., has amassed nearly $25 million in federal campaign accounts, giving him one of the largest political war chests among potential Democrat contenders for the party's 2028 presidential nomination.

Kelly's political team also said he has helped raise and distribute a combined $10 million for Democrat candidates and party committees ahead of the 2026 midterm elections, further boosting his standing within the party.

Kelly told The New York Times his fundraising is aimed at helping Democrats regain control of Congress.

"We can win back the House and the Senate, but it's not going to be easy, and it takes resources, and I want to make sure that I do everything I can to help get people across the finish line," Kelly said.

According to his team, Kelly has directed $2 million to the Democratic National Committee and $3.5 million to the Democratic Senatorial Campaign Committee. He has also raised money for Democrat Senate candidates Roy Cooper of North Carolina and Mary Peltola of Alaska.

Kelly's fundraising accelerated after President Donald Trump criticized him and five other Democrat lawmakers over a video telling active-duty service members they could refuse unlawful military orders.

Trump accused the lawmakers of "sedition" and shared a social media post suggesting they would have been hanged during former President George Washington's era.

Federal prosecutors later sought an indictment against Kelly, but a Washington grand jury declined to bring charges. War Secretary Pete Hegseth also pursued disciplinary action against Kelly, a retired Navy captain, before a federal appeals court panel indicated it was unlikely to support the effort.

Kelly, a former NASA astronaut and the husband of former Rep. Gabby Giffords, D-Ariz., raised more than $25 million during the final quarter of 2025 and the first quarter of 2026 combined. His campaign added another $5.6 million in the second quarter, according to his team.

His fundraising network has reportedly also benefited other Democrats, generating nearly $500,000 for veterans and candidates with national security backgrounds. Sen. Jon Ossoff, D-Ga., has received more than $400,000 in fundraising support or direct contributions from Kelly's operation.

Kelly has campaigned in battleground and early presidential primary states, including Nevada, New Hampshire, and South Carolina, and is scheduled to headline the Ohio Democratic Party's annual dinner next month.

While downplaying the significance of his campaign cash for a White House bid, Kelly acknowledged he is considering one.

"If I was to do it, that's something I think that certainly will help — I've never had a hard time raising money," Kelly told the Times.

He said, "It's a decision I'm going to have to make with my family. I've got plenty of time," adding, "I also have to make a determination whether I think I can win."
