US Rep. Nancy Mace accused of misusing taxpayer funds to cover her DC housing and meals

Mace refused to cooperate with the OCC probe; her lawyer called the report 'fundamentally flawed.'

"The House Ethics Committee is being asked to investigate U.S. Rep. Nancy Mace's food and housing reimbursements after a panel found substantial reason to believe she overbilled when using a taxpayer-funded program to cover her living expenses in Washington, D.C."
, The Post and Courier (Caitlin Byrd), March 2, 2026
Byrd's reporting detailed findings from the Office of Congressional Conduct (OCC) that Mace had claimed nearly $9,500 in excess housing reimbursements connected to her Capitol Hill townhouse, a property valued at approximately $1.6 million, while also billing taxpayers more than $9,400 for food. The OCC referred the matter to the full House Ethics Committee.
The report added a significant detail:
"The Office of Congressional Conduct further recommended the ethics committee issue subpoenas in the case, and stated Mace, R-Charleston, refused to cooperate in their probe."
Mace's lawyer denied the findings, calling the OCC's report "fundamentally flawed." Mace did not immediately comment beyond her attorney's statement.
Roll Call's Washington bureau confirmed the same day that a formal Ethics Committee investigation had opened. The Washington Post ran companion national coverage the following day. The story added a public-corruption dimension to a period of Mace's tenure already marked by litigation and conduct controversy.
