The future of mail-in ballots in some states could hinge on whether those states are willing to hand over voter data to the federal government. On Wednesday, Postmaster General David Steiner confirmed that the U.S. Postal Service plans to stop delivering mail-in ballots in states that refuse to share sensitive voter information, following a proposed rule from the Trump administration.

A Confirmation Under Questioning

Steiner laid out the policy during a hearing before the Senate Homeland Security and Governmental Affairs Committee, where Democratic senators pressed him on the proposal’s implications.

The exchange was direct. Senator Gary Peters of Michigan, the committee’s top Democrat, asked whether the Postal Service would still mail ballots in states that decline to turn over their absentee voter lists to the federal government. Steiner’s answer was unambiguous: under the proposed regulation, no.

He defended the measure as a way to ensure that, in his words, the right ballots reach the right people.

The Origins of the Rule

The proposal traces back to an executive order President Trump issued in March. That order directed the Postal Service to draft a rule requiring states to provide a list of eligible voters at least 60 days ahead of any federal election.

The move fits into Trump’s broader push to crack down on what he describes as mail-in voter fraud, a concern he has raised repeatedly heading into the midterms.

Democrats Sound the Alarm

Democrats have pushed back hard, framing the rule as an attempt to federalize elections, a responsibility the Constitution leaves to the states. They also questioned whether the Postal Service even has the legal authority to enforce such a requirement.

Steiner acknowledged that his agency does not have the power to administer elections. Instead, he characterized the rule as a procedural safeguard meant to ensure ballots only go to eligible voters. He suggested states should actually welcome the arrangement, arguing they would want confirmation that the ballots they intend to send are the ones actually going out.

He also assured lawmakers that the Postal Service would comply with any court orders related to mail-in voting.

A Plea to the Postmaster General

The most pointed moment came from Senator Elissa Slotkin of Michigan, who argued the rule represents an improper attempt by Trump to insert the federal government into election administration. She appealed directly to Steiner to resist.

She urged him not to become a pawn in what she called an authoritarian playbook, describing the Postal Service as one of the nation’s most important institutions and warning him not to let it be tainted by what she characterized as one man’s obsession.

What Comes Next

The timeline is tight. Trump’s executive order instructs the Postal Service to finalize the rule by the end of July. The proposal is currently in the middle of a 30-day public comment period that began earlier this month, giving the public a window to weigh in before any final decision takes effect.

As the debate unfolds, the core tension remains unresolved: a clash between the administration’s stated goal of election security and critics’ fears about federal overreach into a process the Constitution places firmly in the hands of the states.
