A U.S. Postal Service whistleblower is warning that a hastily built mail ballot system designed to comply with President Donald Trump’s executive order could reject tens of thousands of ballots before the November midterms. The anonymous federal employee disclosed that the new online portal was developed in just weeks rather than the typical months required for such a system, raising concerns about operational failures that could disenfranchise millions of voters.
The whistleblower’s disclosure, filed with U.S. Senator Richard Blumenthal on August 31, reveals that the system operates on a “zero percent failure rate” — meaning if even a single barcode fails to scan properly among thousands of ballots in a bulk mailing, the entire batch is rejected and returned to the state, effectively stopping all those ballots from reaching voters. According to ProPublica, USPS staff referred to the development process as a “shit show,” describing it as “secretive, rushed, chaotic, and fundamentally flawed.”
The system stems from a March 2026 executive order in which Trump directed USPS to create new rules requiring states to provide lists of all voters eligible to receive mail ballots. USPS would then use those lists to verify ballot eligibility before delivery. Workers began developing the system in mid-June and were given a September 1 deadline to complete it, according to ProPublica — a timeline that experts say is far too compressed for a sophisticated tracking system.
Top USPS officials expressed concerns in internal meetings that the new rules could delay or block ballots from reaching large numbers of eligible voters, ProPublica reported. Despite these warnings, the directive to reject entire batches for a single unverified ballot moved forward. Election clerks raised the same concerns directly to USPS officials at a mid-August National Association of Election Officials conference in Kansas City, Missouri, citing examples like Maricopa County, Arizona, which sends out more than 2 million ballots in its initial mailing.
Jeff Ellington, CEO of Runbeck Election Services, which prints ballots for counties nationwide, told ProPublica that most counties lack the type of barcodes needed to make the system function. He warned that “trivial things” like file format choices and address specifications “create massive problems” when designing ballot envelopes and getting them approved by USPS in such a short timeframe. Election officials and printing experts have said errors are likely given the difficulty of designing clear, scannable barcodes and maintaining accurate voter data.
The whistleblower’s concerns center on the lack of testing and the absence of internal acknowledgment that errors will occur in the system. Typically, systems are designed with a known error rate, but USPS adopted a policy assuming zero failures — a standard the whistleblower argues is unrealistic for a system built under extreme time pressure. The disclosure also alleges that USPS moved forward with implementation steps during court injunctions that would have violated judicial orders.
The new rule has already faced multiple legal challenges. A federal court temporarily blocked the requirements for states, and the merits are expected to reach the Supreme Court before November. Even if the Supreme Court allows the plan, election officials and experts say the system could not be ready in time for this election, given that ballots for military and overseas voters must be sent out this month. The Supreme Court allowed Trump mail-in voting restrictions to proceed on August 31, lifting some injunctions, but implementation challenges remain severe.
In a statement to ProPublica, a USPS spokesperson said the agency is “carefully reviewing” the whistleblower’s concerns and has spent months developing the system in a manner consistent with court orders. “Regardless of political party or perspective, we share a common goal: ensuring that Americans can have confidence that their election mail will be handled securely and delivered reliably,” the spokesperson said. A White House spokesperson countered that the software development process “is neither complex nor unique for USPS since the Postal Service regularly uses bulk mailing and intelligent mail barcodes for a wide variety of large customers.”
Senator Blumenthal, the Connecticut Democrat who received the whistleblower disclosure, called the new USPS rule a threat to all mail voters and accused the administration of being “hellbent on changing the framework of casting ballots in this country, clearly for political reasons.” He requested detailed information from the Postmaster General about the plan. USPS mail ballots arriving late and getting tossed ahead of midterms has been an ongoing concern, with rejection rates rising in recent elections. USPS whistleblower warns rushed mail ballot system could fail before midterms, according to reporting from earlier in the week.
