Democrats demand inspector general probe USPS whistleblower mail voting claims

House Democrats called on the U.S. Postal Service’s (USPS) inspector general to investigate new whistleblower claims that the agency’s haphazard implementation of President Donald Trump’s anti-mail voting executive order could unleash chaos and disenfranchise millions of voters this November. 

Writing with “extreme alarm,” ranking Democrats on the House Oversight and Administration Committees asked USPS Inspector General Tammy Hull in a letter Wednesday to “immediately” open a probe into the whistleblower’s allegations.

“If the Postal Service proceeds with the implementation of President Trump’s executive order ahead of the 2026 midterm election, and these disruptions occur, a free and fair election is impossible,” the House Democrats told Hull. “You must investigate the Postal Service’s reckless actions, which undermine the foundation of our nation’s democracy and violate the basic principle that all citizens have the right to have their vote counted.”

“Millions of voters could depend on your ability to quickly and thoroughly investigate the Postal Service’s apparent misconduct,” the lawmakers warned.

Alongside House Democrats’ letter to Hull, Sen. Richard Blumenthal (D-Conn.) sent a letter to Postmaster General David Steiner that included a list of questions and record requests regarding the Postal Service’s new mail voting restrictions.

In a report published Tuesday, the anonymous whistleblower alleged that the Postal Service’s new process for verifying mail ballots could result in tens of thousands of mail ballots never being delivered to voters who requested them through no fault of their own.

For many voters, especially those with disabilities, not receiving mail ballots means being disenfranchised.

USPS defied multiple court orders in developing its new restrictions on mail ballots and digital infrastructure to obtain mail voter lists from states, the whistleblower also claimed.

“The allegations are extraordinary, and I do not believe this will be the end of these reports,” Rep. Joe Morelle (D-N.Y.), ranking member of the House Administration Committee, said in a statement Wednesday. “If Trump Administration officials knowingly built a system designed to prevent Americans from receiving their ballots, and blatantly ignored court orders, that is not election security. It is a betrayal of our Constitution and the American people.”

The report landed like a live grenade in a chaotic legal battlefield, where multiple Democratic-led states and pro-voting organizations are challenging new USPS regulations aimed at implementing demands from Trump’s executive order. 

Multiple pro-voting and state plaintiffs have already cited the whistleblower’s allegations in their lawsuits against the new USPS regulations. 

A federal judge in Massachusetts will hear oral arguments in those lawsuits Thursday.

The whistleblower’s account was prepared by the nonprofit legal group Whistleblower Aid and released by Blumenthal’s office.
