USPS Postmaster General Confirms Plan to Block Mail Ballots Without State Voter Data
Postmaster General David Steiner told lawmakers Wednesday that the U.S. Postal Service will refuse to deliver mail-in ballots for federal elections unless states hand over their complete lists of absentee and mail ballot voters to the Trump administration. The testimony, delivered before the Senate Homeland Security and Governmental Affairs Committee, marks the clearest signal yet that the Postal Service is prepared to enforce a sweeping new regulation that critics say would effectively give the White House veto power over mail voting.
"Under our proposed regulation, no," Steiner responded when asked by Senator Gary Peters (D-Mich.) whether USPS would process election mail from states that declined to comply. "We would tell the state that we need the manifest." The proposed rule, published in the Federal Register earlier this month, would require state election officials to submit the names and addresses of every voter who requests a mail-in or absentee ballot at least 30 days before ballots are mailed. If a state refuses, USPS would simply not transport those ballots.
Democrats on the committee immediately condemned the proposal as an unconstitutional power grab. Peters told Steiner the rule would "coerce" states into surrendering sensitive voter data that has traditionally been controlled at the state level. "You are going to make a decision that people cannot vote by mail. That's unacceptable," Peters said. The hearing had originally been scheduled to discuss postal operations, but was quickly overtaken by the election mail issue.
The Rule in Detail: What the Proposal Requires
Under the proposed regulation, state election officials would need to provide USPS with a detailed manifest of all voters who have requested absentee or mail-in ballots for any general, special, or runoff federal election. The list must include names, addresses, and unique tracking barcodes for each ballot envelope. USPS would then cross-check the manifest against the ballots it receives for processing. Any ballot that does not appear on the state-submitted manifest would not be delivered.
The Postal Service has argued that the requirement is necessary to improve security and traceability. In its Federal Register filing, USPS stated that the lists would "facilitate law enforcement efforts" by allowing authorities to compare the number of ballots mailed to the number received, helping to detect potential fraud. Steiner defended the proposal by describing it as an extension of "Kit 600," a set of best practices USPS currently provides to election officials for handling election mail. However, Senator Peters countered that Kit 600 is a voluntary advisory tool and not comparable to a mandatory, enforceable regulation backed by the threat of non-delivery.
The rule does not apply to primary elections, nor to ballots sent to military and overseas voters. It applies only to federal general, special, and runoff elections. But critics note that this carve-out does little to reduce the scale of the impact—mail-in voting has become a central component of American elections, with tens of millions of ballots cast by mail in recent cycles. In states like Oregon, Colorado, Washington, Utah, and Hawaii, mail voting is the default method for all voters.
Background: The Executive Order That Started It All
Steiner’s proposal is a direct response to an executive order signed by President Donald Trump on March 31, 2026, titled "Ensuring Citizen Verification and Integrity in Federal Elections." The order marked one of the most aggressive attempts by a sitting president to reshape election administration. It directed the Department of Homeland Security to compile a federal list of confirmed U.S. citizens eligible to vote, derived from citizenship and naturalization records and other federal databases, and transmit that list to states. It also explicitly instructed USPS to send absentee ballots only to voters appearing on federally approved lists.
Trump has long claimed, without providing evidence, that mail-in voting is prone to widespread fraud. He has repeatedly targeted the practice since the 2020 election, when expanded mail voting during the COVID-19 pandemic was credited with boosting turnout. The executive order is part of a broader push by the administration to impose uniformity on state-run election systems, which under the U.S. Constitution are largely the responsibility of state legislatures. The Constitution vests states with the authority to set the "Times, Places and Manner of holding Elections for Senators and Representatives."
Several Democratic-led states and voting rights groups have already filed lawsuits challenging the executive order and the USPS rule. Last week, a federal judge ruled that those challenges could proceed, setting the stage for what is likely to be a protracted legal battle over the limits of federal power in election administration.
Bipartisan and Democratic Backlash Grows
The day before Steiner’s testimony, all 47 members of the Senate Democratic Caucus sent a letter to USPS leadership urging the agency to withdraw the proposal. The letter, led by Senator Peters, described the rule as an "unconstitutional and illegal attempt to transform USPS into an election administration agency controlled by the White House and President Trump." It warned that the change would "fundamentally upend" the historical role of the Postal Service as a neutral, nonpartisan carrier of election mail.
During the hearing, Senator Margaret Hassan (D-N.H.) called the proposal "blatantly illegal" and demanded Steiner withdraw it "immediately." Senator Elissa Slotkin (D-Mich.) went further, accusing Steiner of being a pawn in Trump’s campaign to undermine confidence in elections. "You are being used by President Trump," Slotkin said. "He does not believe elections that he loses are valid elections."
While no Republican senators on the committee openly endorsed the proposal, the partisan divide was clear. Democrats framed the issue as a fundamental attack on voting rights and state sovereignty. Republicans have generally remained silent or deferred to the administration, though some have expressed concerns about the precedent of a federal agency effectively halting mail voting in noncompliant states.
Legal, Constitutional, and Logistical Stakes
The proposed rule raises multiple legal questions. The first is constitutional: can a federal agency—especially one that has historically been independent—impose conditions on ballot delivery that effectively force states to share voter data? Legal experts are divided. Supporters of the rule argue that USPS, as a service provider, is entitled to set terms for the use of its infrastructure. Opponents counter that the Postal Service is a government monopoly, and that refusing to deliver election mail based on a state’s political choices is a form of coercion that violates the Elections Clause of the Constitution.
There are also practical concerns. States that administer all-mail elections would face an impossible choice: hand over their entire voter rolls to the federal government, or abandon their election system altogether. Oregon, which has conducted all elections by mail since 1998, could not easily switch to in-person voting on short notice. The same applies to Colorado, Washington, and other states. The rule would also create significant administrative burdens for states that do comply, requiring them to compile and transmit manifests weeks before ballots are sent—a timeline that some election officials say is unrealistic given the compressed windows between primaries and general elections.
Senate Democrats have also warned that the rule could be used to disenfranchise eligible voters whose names inadvertently do not appear on the federal citizen list. The DHS citizenship list is still being compiled, and voting rights advocates have raised concerns that it may contain errors, exclude naturalized citizens, or fail to account for Americans who do not have up-to-date records in federal databases. If a voter’s name is missing from the state-submitted manifest, or from the federal list, they would receive no ballot—and there is currently no mechanism in the rule for them to appeal or correct the error in time to vote.
Broader Implications: What This Changes
This is not just a fight about mail ballots. It represents a fundamental shift in how the federal government interacts with state election systems. The USPS has delivered election mail for decades without requiring states to disclose voter information. By conditioning service on data-sharing, the Postal Service would effectively insert itself—and by extension, the White House—into a role that has traditionally been reserved for state and local election officials.
If upheld, the rule could set a precedent for other federal agencies to impose similar conditions on services states rely on. It also raises questions about the independence of the Postal Service, which was established as an independent agency within the executive branch but has historically operated without direct White House control over election-related decisions. Steiner’s appointment and his willingness to implement the president’s agenda have led critics to argue that the agency’s independence has been compromised.
The midterm elections in November 2026 will be the first major test of this rule, assuming it survives legal challenges. Voters in states that resist could find their ability to vote by mail severely curtailed, potentially affecting turnout in key races that will determine control of Congress. The lawsuits now underway are expected to move quickly, but with the election cycle already underway, time is running short for a definitive judicial resolution.
In the meantime, election officials in multiple states are scrambling to assess their options. Some have said they will refuse to comply and are prepared to sue. Others are quietly preparing to hand over the data, betting that compliance is safer than litigation. The outcome of this standoff will likely shape not just the 2026 midterms, but the future of election administration in the United States for years to come.
