The U.S. House Ethics Committee has opened a formal inquiry into South Carolina Rep. Nancy Mace following a referral from the Office of Congressional Ethics, which alleged that the third‑term Republican improperly sought reimbursements through a program designed to offset the housing and living costs lawmakers incur while working in Washington, D.C. The referral and the committee’s acknowledgment of its review were first reported by MyNorthwest, citing Associated Press reporting.

According to the Office of Congressional Ethics, the office concluded after its preliminary investigation that there was “substantial reason to believe” Mace received reimbursement amounts above her actual Washington lodging costs during 2023 and 2024. The reimbursement program covers a share of food, travel, and housing expenses for members of Congress who maintain residences both in Washington and in their home districts.

The referral states that Mace collected approximately $9,500 more than the office believes she should have been eligible to receive for a Washington‑area home she shared with her then‑fiancé. The report further noted that Mace declined an interview request during the review, leaving investigators unable to establish why she sought the maximum allowable reimbursement in months when her expenses appeared to fall below that threshold.

The Office of Congressional Ethics also acknowledged that Mace’s lodging expenses may have exceeded the reimbursement cap in some months, but stated that its evidence “suggests Rep. Mace did not take appropriate measures to ensure she sought reimbursement for expenses actually incurred.”

In a December letter to the committee, attorney William Sullivan Jr. disputed the referral and argued that materials related to the investigation may have originated from Mace’s former fiancé, whom he described as engaged in “an ongoing campaign to discredit and injure the Congresswoman.” According to reporting by MyNorthwest, Sullivan wrote that any such material would raise “serious credibility concerns,” and he criticized the Office of Congressional Ethics for declining to clarify whether the former fiancé played a role in the inquiry.

Rep. Michael Guest, a Florida Republican who chairs the House Ethics Committee, confirmed that the committee received the referral in December. Guest emphasized that the panel’s decision to open an investigation does not constitute evidence of misconduct and said the committee will not comment further until its review is complete.

Although the investigation concerns a South Carolina lawmaker, the procedures and oversight mechanisms involved are the same ones that govern members of Washington State’s congressional delegation. The outcome of the review may shape future debates about reimbursement transparency, officeholder accountability, and the standards applied to publicly funded support programs across the House.

Why this matters for Southwest Washington

The reimbursement system under scrutiny is used by members of Congress from every state, including those representing Cowlitz County and the wider I‑5 corridor. Any changes stemming from the investigation—whether procedural reforms or shifts in enforcement—could influence how elected officials document expenses, manage housing arrangements, and report public reimbursements. The inquiry highlights a broader national conversation about public trust and financial compliance within Congress, subjects that have direct relevance to local expectations of transparency and stewardship.
