A newly released whistleblower complaint reveals details about the “rushed” effort by the Trump administration and U.S. Postal Service to install three new restrictive IT systems that would potentially deny thousands of mail-in ballots, if the federal government disagrees on their eligibility.
According to the complaint, written by attorneys at the nonprofit Whistleblower Aid and released by Sen. Richard Blumenthal, D-Conn., the individual is a federal employee with “direct knowledge of potentially catastrophic problems” related to USPS’ handling of mail-in ballots for the upcoming 2026 midterm elections.
The person claims that USPS is deploying entirely “new and untested” IT systems, including a new Federal Ballot Mail Portal that would potentially give USPS more control over when and whether states receive federal mail ballots for their voters.
The disclosure describes the portal and other systems as “new IT systems and corresponding protocols [that] will govern the delivery of ballots to voters as soon as the 2026 mid-term federal elections and beyond.” It calls the development process “secretive, rushed, chaotic and fundamentally flawed,” and part of a larger effort by agency leaders to rush implementation of the system ahead of the 2026 elections.
That rush has forced USPS to forgo much of the pre-release testing of those systems to ensure they work as intended and can safely interoperate with other federal systems. As a result, the whistleblower says the portal is so restrictive it can potentially reject large batches of state mail-in ballots based on a single identified ballot error.
According to the letter, there are three primary new IT systems USPS is rolling out this election cycle. The Federal Ballot Mail Portal stores both voter names and newly placed ballot barcodes, while a new verification system will compare ballot batch manifests with information in the portal. A third system is described as a new physical barcode sampling verification standard “with a zero percent failure rate.”
“The Whistleblower paints a dire picture of a slapdash software development process as the USPS attempted to create this complex IT system, with multiple points of ballot review, in a matter of weeks,” the letter said. “The very manner in which the project is being developed deviates dangerously from even the most basic software development best practices.”
In all three cases, the onus is explicitly placed on state election officials to resolve discrepancies between federal and state systems.
For example, when the federal government and election officials have different data on batch manifests, which can include tens of thousands of ballots, “election officials will be responsible for resolving any errors purportedly identified in the scan, and for resubmitting the batch manifest – USPS will refuse to accept the ballot batch until the errors are resolved.”
