Contractor may have used Grok to falsify VA financial records, CBCA finds

The Civilian Board of Contract Appeals dismissed a contractor's $4.23 million claim against the Department of Veterans Affairs this month after concluding that someone at the company most likely used Grok (xAI's generative AI tool) to alter audited financial statements entered into discovery. The August 18 filing is, according to procurement attorney David Timm, the first time a federal tribunal has found that generative AI was used to manipulate contract dispute documents, and it opens a new front in procurement fraud enforcement that the government isn't equipped to police.

VA's construction damages expert flagged the altered documents after struggling to reconcile Venergy's financials with data the department had previously received. Someone had placed electronic white boxes over three years of audited statements (2020, 2022, and 2023) concealing schedules of earnings, contracts in progress, and completed contracts. The board found the manipulations had inflated Venergy's claimed damages by more than $1.1 million.

The CEO's Grok enthusiast

At a July 2026 fact-finding hearing, Venergy's CEO and external CPA both testified that neither of them had altered the records. But the CEO acknowledged that a now-former employee (someone the CEO described as "a proponent of Grok") had access to the CEO's Adobe Acrobat account and could have manipulated the documents. The company hadn't contacted the former employee or conducted any internal investigation, the board noted. Venergy produced clean copies in February 2026 and called the VA's allegations inaccurate. The board dismissed the $4.23 million claim as a sanction while allowing the company's appeal of the underlying contract termination and the government's $1.84 million counterclaim to proceed.

The detection gap

The case sits at an intersection of procurement law and criminal exposure the government hasn't had to navigate before. Under the False Claims Act, knowingly submitting a false claim carries treble damages plus per-claim penalties. A VA Office of Inspector General investigation into the manipulated records is already underway, and Timm told Nextgov/FCW that criminal charges could follow if DOJ can establish who falsified the documents and that they did so with intent.

But the harder problem is detection. "Either it depends on whistleblowers or something so obviously bad that a human can detect it," Jessica Tillipman, associate dean for government procurement law studies at George Washington University Law School, told Nextgov/FCW. "But as AI tools get more sophisticated, it's going to be increasingly difficult for people to detect AI fraud." Tillipman said the federal government is "fully unprepared for how bad this is going to get."

The CBCA finding lands in a procurement fraud environment already under exceptional scrutiny. GSA announced $13 billion in suspected procurement fraud on August 25 (a record for the agency) and earlier this month Trax International alleged in a Court of Federal Claims complaint that the Army used hallucinating AI to evaluate bids on a $450 million contract. The Venergy case is the first to move the AI question from bid evaluation to document integrity in dispute resolution, and it won't be the last.
