Rep. Nancy Mace, South Carolina Republican, is facing a House Ethics Committee investigation over allegations she improperly billed her congressional office for expenses tied to her Washington, D.C., home — and the fallout could shape the trajectory of her political future.
Here’s what to know about what comes next.
The investigation itself
The Ethics Committee is now reviewing an Office of Congressional Conduct report that found “substantial reason to believe” Ms. Mace engaged in improper reimbursement practices. All six members of the nonpartisan Congressional Conduct board voted unanimously to refer the matter to the committee.
The OCC alleges Ms. Mace consistently claimed the maximum allowable reimbursement from a program designed to help House members cover D.C. living costs, despite owning only a 28% stake in the property, which she co-owned with her former fiance, Patrick Bryant. A review of invoices and other documents found discrepancies amounting to nearly $9,500 in excess payments between 2023 and 2024.
The committee will now determine whether to open a full investigation, dismiss the matter, or pursue a formal sanction. That process can take months — or longer.
Mace’s defense
Ms. Mace’s attorney, William Sullivan, is pushing back hard, calling the OCC report “fundamentally flawed in several significant respects.” Sullivan argued the report relies on unverified information potentially sourced from Mr. Bryant himself — the same man Ms. Mace publicly accused of sexual misconduct in a House floor speech last February. Mr. Bryant has denied those accusations and filed a defamation suit against Ms. Mace.
Mr. Sullivan also noted that Ms. Mace “remains available to provide any additional information” to the committee — a notable posture given the OCC’s finding that she declined to be interviewed during the initial review.
Her governor’s race
The timing couldn’t be more complicated for Ms. Mace, who is running for governor of South Carolina. An active ethics investigation — even one that ultimately goes nowhere — gives opponents fresh ammunition and forces her campaign to spend time and resources on damage control.
South Carolina’s Republican primary is a competitive field, and Ms. Mace’s already turbulent public profile — which includes a reported altercation with officers at Charleston International Airport last November, which she has denied — means the investigation adds another layer of scrutiny she’ll need to navigate.
Her ethics push on the House floor
In an irony that hasn’t gone unnoticed, the investigation comes just days after Ms. Mace introduced a resolution pressing the House Ethics Committee to publicly release all documents related to lawmakers accused of sexual misconduct. She plans to force a floor vote on the measure Wednesday.
Whether that effort gains traction — or becomes overshadowed by her own ethics referral — remains to be seen.
The bottom line
Ms. Mace has long thrived on controversy, using it to build a national profile and energize her base. But a formal Ethics Committee investigation is a different kind of fight — one fought behind closed doors, on a timeline she doesn’t control, with potential consequences that extend well beyond the news cycle.
