Whistle-blower warns USPS postal voting risks before midterms

Whistle-blower warns USPS postal voting risks before midterms

A federal whistle-blower says the U.S. Postal Service is still building an untested Federal Ballot Mail Portal tied to President Trump's mail voting executive order ahead of the November midterms, despite court friction—raising risks that batches of postal voting ballots could be delayed or returned if a single barcode fails verification. The claim, disclosed to Sen. Richard Blumenthal and reported by CBS News, puts a rushed tech rollout at the center of the fight over how Americans cast ballots by mail.

Key Takeaways

What did the whistle-blower allege about USPS?

Lawyers for Whistleblower Aid described the source as a federal official with direct knowledge of the project. In a disclosure made public Tuesday, the whistle-blower said USPS continued work on implementing Trump's order to tighten mail voting rules even as courts constrained enforcement.

The official called the new Federal Ballot Mail Portal "untested" and warned of "significant operating problems" from "rushed" development. Blumenthal told reporters the Postal Service had "designed a system to disenfranchise millions of Americans," noting that about one third of Americans vote by mail.

In a Monday letter to Postmaster General David Steiner, Blumenthal called the rollout "perilously rushed and potentially unlawful" and urged the agency to walk back its plans for the upcoming elections.

How would the new postal voting portal work?

Under a final USPS rule published last month, outbound and return ballot envelopes would need new design standards, including a unique barcode. State election officials would submit to the online portal the names and addresses of voters receiving mail ballots, plus those barcodes.

Voters listed that way would be enrolled on a state's "Mail-In and Absentee Participation List." USPS said it "will not play any role in determining voter eligibility, maintaining voter rolls, or counting ballots." The agency said it spent months building the portal as a "simple, secure, and efficient" way for officials to share lists and will "soon" make it available voluntarily.

The whistle-blower's account of verification is stark: workers would scan a sample—about 400 pieces from a batch of 10,000 or more—against portal data. If even one barcode fails or information does not match, the entire batch would be rejected and returned to state officials for fixing before the process restarts. Lawyers called that design "entirely unforgiving" and said it could delay ballots by the thousands. Election-law analyst David Becker warned of "tremendous" disenfranchisement concerns.

Where do courts and election officials stand?

A federal judge temporarily blocked enforcement of the new rule last week; the Justice Department has appealed. After an earlier June block by U.S. District Judge Indira Talwani, the Supreme Court later lifted that order on procedural grounds, stressing that future implementation steps may still be unlawful. In a brief Monday order, Talwani said USPS may establish the portal and talk with states about design standards "so long as states' participation is not required."

The whistle-blower contends workers kept building the portal after injunctions; USPS said its work has "at all times been conducted in a manner consistent with court orders" and that it is reviewing Blumenthal's concerns. Separately, CNN reported that local election officials say Trump's effort to remake mail-in voting rules is impossible to implement. North Carolina was set to begin sending some mail ballots soon after the disclosure, with other states following around mid-September—leaving little runway if the untested system falters.
