Democratic Sen. Richard Blumenthal released a whistleblower statement on Tuesday, Sept. 1, 2026, alleging that the U.S. Postal Service rushed construction of its Federal Ballot Mail Portal in three months instead of the typical year-plus, skipped full testing, and created a system that could jeopardize mail voting relied on by about one-third of all voters. ^[1] The whistleblower said the new procedures impose a 'zero percent' rule so a single apparent error during three scanning checks could cause the Postal Service to discard an entire batch of tens of thousands of ballot envelopes, potentially denying voters their mail ballots. ^[2] Democratic Sen. Richard Blumenthal released a whistleblower statement on Tuesday warning that the U.S. Postal Service is implementing a flawed computer system to enforce President Donald Trump's executive order limiting mail voting. ^[3] A US Postal Service employee filed a whistleblower report alleging the agency is implementing a Trump executive order on mail-in voting in a 'secret and rushed' manner, despite a federal court order blocking the plans. ^[4] The report warns that the risky implementation could cause a catastrophic failure of the mail-in voting system before the midterm elections, potentially preventing millions of voters from receiving their ballots on time or at all. ^[5] An anonymous USPS worker filed a complaint regarding the risks of a new federal mail-in voting system being implemented by the Trump administration. ^[6] A United States Postal Service official filed a whistleblower report with the office of Sen. Richard Blumenthal, D-Conn., alleging that the agency is moving forward with a secretive and rushed effort to implement President Donald Trump's order exerting federal control over mail voting. ^[7] The whistleblower warned that potentially millions of American voters may not receive their mail-in ballot this election cycle in a timely manner, or at all. ^[8] On 2026-03-21, the USPS established new rules ordered by President Trump's executive order signed in March 2026, requiring states to receive a federal federal approval for the use of tracked barcodes on mail-ballot envelopes and to supply the Postal Service with lists of registered voters. ^[9] On 2026-04-01, U.S. Senator Richard Blumenthal (D-CT) released a whistleblower report from an unnamed USPS employee alleging that the Trump administration’s readmail voting restrictions could disenfranchise many American voters. ^[10] The whistleblower claimed that if only one of the 10,000 ballots in a state batch is found inconsistent, the whole batch of 10,000 would be rejected, causing delays or cancellation of mail ballots and making votes impossible. ^[11] Election officials in North Carolina warned that the new Federal Ballot Mail Portal could not be implemented before the first mail ballots begin going out in the state on Friday, Sept. 4, 2026. ^[12]
