Arizona Democratic Senator Ruben Gallego has filed to create a legal defense fund to address ongoing allegations of sexual misconduct and campaign-finance violations, according to newly released IRS documentation. The U.S. Senate legal expense trust, established on May 22, 2026, is named the Senator Ruben Gallego Legal Defense Fund and explicitly identifies Gallego as its beneficiary.

The filing follows reports that Rep. Anna Paulina Luna alleged in April that an unnamed senator faced disturbing misconduct claims, later identifying Gallego during a CBS News interview. Luna described allegations involving sexual misconduct and campaign-finance violations, though CBS News noted it had not verified the claims at the time of reporting. Senate Majority Leader John Thune referred the matter to the Senate Ethics Committee after Luna directed the complaint to leadership.

Gallego’s office has characterized the allegations as “right-wing conspiracy theories” and stated the fund was formed in response to criticism from Luna, the Trump administration, and allied critics. The legal defense vehicle operates under specific rules: contributions over $25 must be disclosed quarterly to the Senate Ethics Committee, individual donors are capped at $10,000, and corporations, unions, lobbyists, foreign agents, and Senate employees are prohibited from contributing.

Gallego’s move comes amid heightened scrutiny of his recent associations, including connections to former Representative Eric Swalwell, who resigned from Congress and withdrew from the California governor’s race following misconduct allegations. The IRS filing confirms the fund is tied directly to Gallego’s Senate position and legal expenses related to unresolved ethics complaints.

The establishment date—late May 2026—aligns with Luna’s public escalation of the allegations and Thune’s referral to the Senate Ethics Committee, marking a formal shift from campaign-level disputes into documented legal preparation as the controversy continues.
