Senator Ruben Gallego (D-AZ) is under federal investigation by the U.S. Department of Justice for suspected campaign finance violations, according to.
The probe originated from a whistleblower complaint filed from Southern California, the outlet reported.
The investigation centers on the use of funds from Gallego’s political action committee for family travel and related expenses. Specific examples cited in connection with the allegations include trips to Miami, Chicago, Disneyland, and Disney World.
These matters were previously examined as part of a separate congressional ethics process.
A review of federal campaign finance records from Politico detailed additional spending by Gallego’s campaign committee and his leadership PAC, Juntos PAC. The records show more than $18,000 in reimbursements for child care since 2019, including payments to an au pair company and a $400 payment to Gallego’s mother-in-law for babysitting during a campaign fundraiser.
The leadership PAC covered costs for family travel to locations including a Miami Beach hotel stay exceeding $9,000 for a birthday celebration that also involved political events, a Chicago trip with nearly $1,500 in lodging that included a fundraiser, and meals and hotels at Disneyland and Disney World totaling nearly $1,500 (excluding flights).
Family members, including Gallego’s wife Sydney, their children, and an au pair, joined multiple trips. A joint fundraising committee with former Rep. Eric Swalwell also covered expenses related to the 2023 Super Bowl in Arizona, including event tickets and a pre-game brunch.
Gallego has stated that the expenditures comply with Federal Election Commission rules. In response to the Politico reporting, he wrote that such travel with family members for campaign and fundraising purposes is permitted and occurs regularly among members of Congress from both parties, noting the rising costs of child care.
A spokesperson for Gallego described the Miami trip as part of a multi-stop political and fundraising swing and the Chicago trip as including a fundraiser and attendance at political events.
Juntos PAC, established in February 2024, has raised nearly $1.5 million, with more than half of the funds coming from corporate PACs. Leadership PACs are subject to different rules than principal campaign committees and allow greater flexibility for expenditures tied to fundraising activities.
Gallego’s office has noted that the senator proactively established a legal defense fund in the preceding month.
The investigation follows the closure of an inquiry by the Senate Select Committee on Ethics. In a letter dated June 26, 2026, the committee informed Gallego that it “did not find evidence that your actions violated Federal law, Senate Rules or related standards of conduct.” The ethics inquiry stemmed from a complaint filed in April by Rep. Anna Paulina Luna (R-FL), which alleged campaign finance violations and inappropriate conduct of a sexual nature.
Gallego, who was sworn in as Arizona’s junior senator in January 2025, after he defeated Republican Kari Lake in the 2024 election, has long been identified as a potential candidate for the 2028 presidential nomination. Earlier in June 2026, he hired former Biden White House deputy press secretary Andrew Bates to assist with communications, which further fueled presidential speculation.
