A federal judge called it what it was: an unconstitutional power grab dressed up as election security.

"The Constitution does not grant the President any specific powers over elections."

— U.S. District Judge Indira Talwani, blocking Trump's mail-voting executive order

On Wednesday, Postmaster General David Steiner appeared before the Senate Homeland Security Committee and delivered an answer that should have been impossible in a functioning democracy. When asked whether the US Postal Service would deliver mail-in ballots to states that refused to hand their voter rolls to the Trump administration, Steiner said no.

"Under our proposed regulation, no," Steiner told the committee. "We would tell the state that we need the manifest."

Sen. Gary Peters, the panel's ranking Democrat, did not mince words. He called the proposal coercion, a backdoor mechanism for the federal government to seize control of voter data that the Constitution reserves for the states.

"You're making a decision that people cannot vote by mail," Peters said. "That's unacceptable."

Steiner's response was a masterclass in bureaucratic dodge: he said the rule was subject to litigation and declined to commit to delivering ballots in any specific state.

Translation: the person running the nation's post office is openly negotiating which Americans get to vote by mail, and his leverage is the threat to stop delivering their ballots entirely.

The root of the crisis is an executive order Trump signed on March 31, 2026, titled "Ensuring Citizenship Verification and Integrity in Federal Elections." The document is dense and legalistic, but its effect is straightforward. It requires the USPS to deliver absentee ballots only to voters on lists created and approved by the federal government. It directs the Department of Homeland Security to build those lists using federal databases. And it demands individualized barcode tracking on every ballot envelope, with data shared with mail carriers and election authorities.

The USPS responded by publishing a proposed rule on June 5 that operationalized the order. States must submit their mail voter lists at least 30 days before ballots are sent. Voters not on the list do not get a ballot. The effect is a federal voter registration system built through the postal system, bypassing Congress and state legislatures entirely.

What makes this especially audacious is that the USPS itself was created by Congress in 1971 as an independent agency, explicitly separated from White House control. The Postal Service's own rule, adopted under Steiner last year, states that the agency "does not administer elections, establish the rules or deadlines that govern elections, or determine whether or how election jurisdictions utilize the mail."

Steiner seems to consider last year's rule obsolete.

The backlash was immediate. The American Postal Workers Union called the proposal an "unconstitutional attack on the millions of Americans who vote by mail" and rejected the premise that USPS had any obligation to comply with the executive order.

"The Postal Service serves all Americans, regardless of party, religion, or race," the APWU said. "It is not a tool for politicians to pick which Americans get which benefits."

Illinois Gov. JB Pritzker promised legal resistance, calling the plan "voter suppression" rather than election security. Sen. Richard Blumenthal of Connecticut told Steiner plainly: "You run the Postal Service, you deliver the mail. You don't review ballots or registration. Nobody said you should. This proposed rule is bogus."

Aaron Reichlin-Melnick, senior fellow at the American Immigration Council, summed up what many legal observers were thinking: "Yeah, that's illegal. The Post Office can't refuse to deliver mail to try and get policy concessions."

The NAACP filed a separate lawsuit against the USPS on Thursday, alleging that the proposed rule violates a court-enforced settlement from 2021 in which the Postal Service agreed to safeguard mail-in voting and prioritize timely ballot delivery through 2028.

Then came the ruling. On Thursday, U.S. District Judge Indira Talwani, an Obama appointee sitting in Boston, blocked major parts of the executive order for 23 Democratic-led states and the District of Columbia. She halted the administration from creating a federal program to "superintend and control" state voter rolls. She blocked prosecutions of election officials in those states under the order's terms. And she explicitly cited the Constitution.

"The Constitution does not grant the President any specific powers over elections," Talwani wrote.

The ruling is partial and temporary. It applies only to the plaintiff states and does not permanently invalidate the order. The Trump administration is expected to appeal. Meanwhile, a separate case in Washington, DC, before Judge Carl J. Nichols, a Trump appointee, has not yet issued a preliminary injunction. Nichols said the main reason was that the administration had not yet fully implemented the rules or stopped anyone from receiving ballots.

But Talwani's decision is significant because it names the structural problem. The executive order is not a technical adjustment to election procedure. It is a fundamental reordering of authority, shifting power from states to the federal executive, from Congress to the White House, from the voters to the people who decide which voters get mail service.

The citizenship verification angle deserves scrutiny on its own merits. DHS has been using a federal database known for producing false positives to hunt for non-citizen voters on state rolls. A separate federal ruling this week blocked the use of that same citizenship data system for purging voter rolls in Washington, DC, recognizing the risk of eligible citizens being wrongly removed.

A Justice Department filing revealed last week that DHS is exploring data sharing with USPS to "monitor mail-in and absentee ballot flows, identify anomalies that may suggest voter fraud or misuse, and generate authorized investigative leads."

The phrase "identify anomalies" is notable. It is the kind of language that lets an agency cast a wide net, flagging ordinary patterns of voter behavior as suspicious, without admitting to targeting any specific demographic.

Meanwhile, election officials in California and Wisconsin have already reported that ballot delivery times have slowed since the USPS began making policy changes under Trump. The changes were framed as efficiency improvements. The results looked more like delays.

The broader picture is that the Trump administration has been trying for months to pass SAVE Act legislation through Congress, which would require proof of citizenship to register to vote and severely restrict the documents states can accept. The bill stalled, as it requires legislative majorities that the administration does not have. So Trump signed an executive order instead, using the Postal Service as the enforcement mechanism.

When Congress failed to act, he used the Postal Service to try to accomplish the same goal through administrative fiat. When courts began pushing back, his Postmaster General took to a Senate hearing to announce that noncompliant states would lose their mail ballots.

It is a pattern. Legislation blocked, so executive orders. Executive orders challenged, so agencies are told to enforce them anyway. Courts intervene, and the administration treats the ruling as a temporary inconvenience rather than a legal boundary.

The question is not whether this was unconstitutional. The question is why anyone thought the threat to withhold mail delivery would be anything other than an act of political warfare against the voters who tend to vote by mail.
