House Ethics Committee Investigation of Rep. Nancy Mace (OCC Review 25-5681)
The Office of Congressional Conduct voted 6-0 to refer Rep. Nancy Mace to the House Committee on Ethics, finding substantial reason to believe she engaged in improper reimbursement practices; the Committee is continuing its review and has made no finding of a violation.
The Office of Congressional Conduct (OCC) voted 6-0 on November 18, 2025 to refer Rep. Nancy Mace to the House Committee on Ethics, finding "substantial reason to believe that Rep. Mace engaged in improper reimbursement practices" in her use of the Members' Representational Allowance (MRA) for lodging at a Washington, D.C., property she co-owned with her then-fiancé. The Ethics Committee has acknowledged the referral, extended its review twice, and as of March 2, 2026 continues a formal expanded review. The Committee has made no finding of a violation. Rep. Mace denies any wrongdoing; her counsel calls the OCC report "fundamentally flawed."
A "substantial reason to believe" finding is the OCC's referral threshold, the minimum showing required to advance a matter for further Committee review. It is not a finding that any law or House rule was violated.
The OCC report, as released
The OCC Report and Findings, OCC Review No. 25-5681, was transmitted to the House Committee on Ethics on December 1, 2025. Although the report bears a "CONFIDENTIAL, H. Res. 895" header (the standard confidentiality designation for OCC referrals), the House Committee on Ethics released it publicly on March 2, 2026, posting it to ethics.house.gov alongside a Chairman/Ranking Member press statement. The confidential marking reflects the document's procedural origin; the Committee's public release is the operative act, and the report is reproduced here as a public record.
Cover page. The document is marked "CONFIDENTIAL, H. Res. 895", the standard marking for OCC referrals under House Resolution 895, but the House Committee on Ethics released it publicly on March 2, 2026. The Recommendation states: "there is substantial reason to believe that Rep. Mace engaged in improper reimbursement practices." Board vote: AFFIRMATIVE 6 / NEGATIVE 0 / ABSTENTIONS 0. Presented by Omar S. Ashmawy, OCC Staff Director & Chief Counsel.
Page 5, the four individuals who refused to cooperate with the OCC's review: Rep. Mace, former chief of staff Daniel Hanlon, and former staffers Lorie Khatod and Richard Chalkey. Also listed: the applicable legal standards, 18 U.S.C. § 1001 (false statements), 18 U.S.C. § 641 (conversion of public money), 31 U.S.C. § 1301 (appropriations), and House Rule 23, cls. 1 & 2.
Page 8, ¶21-22. The OCC found that "Rep. Mace requested and received the maximum allowable reimbursement for each month she filed a reimbursement request form." In 2024, her requests exceeded the D.C. property's actual expenses in January, March, April, and May, the month-by-month comparison table shows the excess totaling $9,485.46.
Page 11, ¶30. The OCC reviewed correspondence with the former fiancé's accountant (anonymized as Witness 3), which "suggests that Rep. Mace was entitled to request $2,462.94 in monthly reimbursement, based on the 2022 costs of the DC Property." Mace requested the maximum allowable amount every month she filed; for four of those months her requests exceeded the $2,462.94 figure.
Page 12, ¶31-32. A former Mace staffer (Witness 1), in a verbatim OCC interview transcript: "So when I first started filling out these forms, the Congresswoman and the Chief of Staff would always talk about how it doesn't even come close to covering her living costs… So the max out was, according to them, accurate." ¶35 contains the OCC's recommendation that the Committee issue subpoenas to Rep. Mace, Daniel Hanlon, Lorie Khatod, and Richard Chalkey.
What the report found
The OCC's review covered Mace's MRA reimbursement requests for lodging at a Washington, D.C., property from January 2023 through May 2024. The report's principal findings, drawn verbatim from the public document:
The maximum-reimbursement pattern (¶21). "Rep. Mace requested and received the maximum allowable reimbursement for each month she filed a reimbursement request form."
The $9,485.46 excess (¶22). The OCC found that in 2024 Mace's "requests for reimbursement exceeded the total of the DC Property's expenses in January, March, April, and May," an overage the report put at $9,485.46. The report also identifies excess months in 2023: January, February, March, May, June, September, October, and November.
No documented payment (¶25). The OCC reviewed correspondence between Mace and the former fiancé's accountant (Witness 3) "suggesting that while she had received reimbursement from the House for her lodging expenses, as of October 5, 2023, she had not contributed the funds to the bank account associated with the DC Property." The report notes that utility bills were largely in the former fiancé's name and paid from the joint account.
Unable to determine the reason (¶28). "Because Rep. Mace refused to interview in this matter, the OCC was unable to determine how or why Rep. Mace decided to seek the maximum allowable reimbursement when it exceeded her expenses incurred."
The accountant's figure (¶30). Correspondence reviewed by the OCC "suggests that Rep. Mace was entitled to request $2,462.94 in monthly reimbursement, based on the 2022 costs of the DC Property. Rep. Mace requested the maximum allowable reimbursement for every month she filed a reimbursement form; for four of those months, her reimbursement requests exceeded the aforementioned $2,462.94."
The staffer's testimony (¶31). A former Mace staffer, Witness 1, told OCC investigators in a verbatim interview transcript: "So when I first started filling out these forms, the Congresswoman and the Chief of Staff would always talk about how it doesn't even come close to covering her living costs. And so when they checked over, I made sure that they never went over her current living costs. So the max out was, according to them, accurate."
Refusal to cooperate (¶12, ¶34). "The following individuals and entities refused to cooperate with the OCC's review: Rep. Mace; Daniel Hanlon; Lorie Khatod; and Richard Chalkey."
Subpoena recommendation (¶35). "The Board recommends that the Committee on Ethics issue subpoenas to: Rep. Mace; Daniel Hanlon; Lorie Khatod; and Richard Chalkey."
Applicable law. The OCC identified potential violations of 18 U.S.C. § 1001 (false statements to the government), 18 U.S.C. § 641 (conversion of public money or property), 31 U.S.C. § 1301 (purpose of appropriations), and House Rule 23, cls. 1 & 2.
Mace's response
Rep. Mace denies the allegations and has not been found to have violated any law or House rule. Her counsel, William M. Sullivan Jr., characterized the OCC report as "fundamentally flawed" in a December 17, 2025 response letter, asserting that it "appears to incorporate unverified assertions and materials that may have originated from, or been influenced by, Rep. Mace's former fiancé", citing what Sullivan characterized as "a documented history of abusive and retaliatory conduct" by the former fiancé. That characterization is Mace's defense position.
On March 6, 2026, Mace told The Daily Signal: "this is probably retaliation for Epstein, let's be honest" and "When you fight the swamp, the swamp fights back." She also asserted to ABC News 4 that she "incurred over $100,000 in lodging expenses in DC and received approximately $29,000 after taxes in reimbursements."
Mace's office also publicly questioned the OCC's lead investigator, Omar S. Ashmawy, citing what it characterized as a personal matter reported in 2015 as settled; that characterization is attributed to Mace's office and is not independently confirmed here.
