The Federal Election Commission issued a warning to Herschel Walker's joint fundraising committee.
The FEC found multiple errors on the committee's October quarterly campaign finance filing.
Walker faces Democratic Sen. Raphael Warnock in the Georgia Senate runoff election on December 6.
The Federal Election Commission has warned US Senate candidate Herschel Walker's joint fundraising committee that one if its recent campaign finance reports is riddled with accounting errors.
The November 28 letter to Team Herschel's People's Champion Committee highlights discrepancies in a report covering financial activity from July through September, including several incorrect calculations.
The FEC letter offers instructions on how the treasurer can double-check his addition on year-to-date totals and cash on hand. "Cash on hand at the close of the current reporting period should always equal the closing calendar year to date cash on hand amount," wrote Kevin Fortkiewicz, a senior campaign finance and reviewing analyst.
Walker's committee has until January 3 to respond to the FEC's letter. Failure to respond in time could lead to an audit or "enforcement action."
A Walker spokesperson did not immediately respond to a request for comment.
Walker, a Republican, faces Democratic Sen. Raphael Warnock on December 6 in Georgia's US Senate runoff election. Neither Warnock nor Walker cleared the 50% threshold during the general election on November 8, triggering the runoff.
Such warning letters from the FEC are common for large political committees that raise and spend significant money and, at times, make accounting mistakes. The FEC in 2021, for example, flagged Warnock's campaign for accepting contributions that exceeded federal donation limits.
The outcome, however, can be serious, leading to not only bad headlines but federal fines if campaigns don't quickly and adequately rectify the problems.
Bad press has already been a problem for Walker, who has been plagued by allegations that he was hiding "secret" children and that he paid for a former girlfriend's abortion and forced another to have one. Some memorable moments for Walker include a bizarre stump speech in which he explained to voters why he'd rather be a werewolf than a vampire and an interview in which he called the election an "erection."
Even so, polls show the race is tight in Georgia, where early voting has started.
A Warnock victory would give Democrats a 51-49 Senate majority while a Walker victory would maintain the Senate's 50-50 split.
