A U.S. Postal Service whistleblower warned that a hastily built mail ballot system tied to President Trump’s executive order could fail before the November midterm elections, potentially disenfranchising millions of voters who rely on mail voting. The anonymous federal official disclosed concerns to Democratic Sen. Richard Blumenthal of Connecticut on August 31, 2026, describing the Postal Service’s work as “secretive, rushed, chaotic, and fundamentally flawed.”
The whistleblower detailed critical flaws in an online portal USPS is building to verify mail ballots under Trump’s March 2026 executive order, which imposed new restrictions on mail voting. According to the disclosure, USPS did not begin developing the portal “in earnest” until June, leaving less than three months to build and test a system expected to handle millions of ballots for the midterms.
The whistleblower highlighted a particularly problematic design feature: USPS has set what it calls a “zero percent failure rate” policy for the ballot verification process. Under this standard, mail workers would scan a sample of ballots—roughly 400 out of every 10,000 in a batch—to verify they match data in the federal mail ballot portal. If even a single barcode fails to scan properly, the entire batch would be rejected and sent back to state election officials, forcing the verification process to restart.
According to the disclosure, this design is “entirely unforgiving” and could delay ballots by thousands in repeated verification cycles, preventing states from mailing enormous numbers of ballots to voters. The whistleblower’s lawyers warned that the new system is “untested” and will have “significant operating problems” when released.
David Becker, executive director of the Center for Election Innovation and Research, told CBS News that the process raises “tremendous” concerns for voter disenfranchisement. He argued that the new Postal Service rules “would undoubtedly create a tremendous number of hoops that are completely unnecessary and do nothing for election integrity.”
The whistleblower also alleged that USPS violated court orders by continuing to work on the portal even after a federal judge temporarily blocked implementation of Trump’s mail voting restrictions in late August. The Postal Service aims to have the system ready by September 1, 2026, according to the disclosure.
Blumenthal said in response to the disclosure that “the Postal Service has designed a system to disenfranchise millions of Americans,” noting that one-third of all Americans cast their ballots by mail. He urged Postmaster General David Steiner to “abandon this ill-conceived, unconscionable plan and ensure that all Americans can exercise their constitutional right to vote, including by mail, without interference by USPS.”
The Trump administration has defended its mail voting restrictions as a safeguard against voter fraud, though studies and audits show such fraud is extremely rare. The president himself has voted by mail in Florida elections, despite his administration’s claims about the security risks of mail voting.
The whistleblower’s disclosure comes amid ongoing litigation over the executive order. A federal judge in Boston issued a temporary restraining order blocking key parts of USPS’s plan after finding it likely unconstitutional, since the Postal Service has no authority to control voting by mail. The Trump administration has appealed that ruling to the 1st U.S. Circuit Court of Appeals, with the case likely heading to the Supreme Court.
