Judge Declines to Block Trump Mail-In Voting Order

A federal judge in Washington, D.C., has declined to temporarily block President Donald Trump’s executive order targeting mail-in voting, handing the administration a significant legal victory while leaving the door open for future challenges. U.S. District Judge Carl Nichols ruled on May 28 that the lawsuit brought by Democrats and voting rights groups was premature, as the order’s directives have not yet been implemented by federal agencies.

The Ruling

Judge Nichols, a Trump appointee, found that the plaintiffs could not demonstrate the concrete harm required for a preliminary injunction. As NPR reported, Nichols wrote that “the Postal Service may ultimately issue a final rule that directly affects Plaintiffs or their members, or that the Government may develop State Citizenship Lists that omit specific individuals.” He added that plaintiffs may renew their motions “if and when those future actions occur.”

The ruling applies to three consolidated D.C.-based lawsuits filed by Democratic Party organizations and voting rights groups, including the League of United Latin American Citizens. The decision was procedural rather than substantive, meaning it did not address the constitutionality of the executive order itself.

What the Executive Order Does

Signed by President Trump on March 31, Executive Order 14399 — titled “Ensuring Citizenship Verification and Integrity in Federal Elections” — directs the Department of Homeland Security to work with the Social Security Administration to create lists of adult U.S. citizens in each state, known as “State Citizenship Lists.” These lists would be sent to state election officials. The order also calls for the U.S. Postal Service to only deliver mail-in ballots to voters on state-specific absentee and mail-in voting lists, and requires states to preserve election-related records for five years.

As Al Jazeera noted, the administration is still developing the rules and procedures needed to enforce the measure, making any potential harms “too speculative for immediate court intervention.”

Legal and Political Context

The ruling arrives amid a broader legal battle over presidential authority in election administration. Opponents argue that Article I, Section 4 of the U.S. Constitution gives state legislatures and Congress — not the president — the power to set rules for federal elections. A separate case is pending in Boston before U.S. District Judge Indira Talwani, an Obama appointee, with arguments scheduled for June 2. That lawsuit involves a coalition of 24 Democratic-led states.

This is not the first time Trump’s election-related orders have faced judicial scrutiny. A 2025 executive order requiring voters to prove U.S. citizenship and barring states from counting mail-in ballots received after Election Day was blocked by three federal judges and is currently under appeal.

Senate Democratic Leader Chuck Schumer, a lead plaintiff in the D.C. case, condemned the order, stating: “Mail-in voting is safe and secure, a hallmark of our free and fair elections. Trump’s order is not about election integrity. It is voter suppression, plain and simple.” As NBC News reported, Democrats argued the order could disenfranchise millions of voters.

Implications for the 2026 Midterms

The 2026 midterm elections — where control of both chambers of Congress is at stake — add urgency to the litigation. In the 2024 election, roughly one-third of all ballots were cast by mail, and more registered Democrats than Republicans reported voting by mail. Critics warn that any disruption to mail-in voting could disproportionately affect Democratic voters, with ballots in some states going out as early as September.

Trump himself voted by mail in Florida in March 2026, despite his longstanding criticism of the practice. The president has cited preventing illegal voting by noncitizens as justification for the order, though reviews and research have found noncitizen voting in federal elections to be incredibly rare.

What Comes Next

Plaintiffs have a 60-day deadline — until late July 2026 — to appeal Judge Nichols’ ruling. The parallel Boston case could produce a different outcome, potentially creating conflicting rulings that may require Supreme Court resolution. Meanwhile, the U.S. Postal Service has not yet issued a public notice about a rulemaking process, despite the order’s directive for Postmaster General David Steiner to begin one by late May.

Danielle Lang, an attorney at Campaign Legal Center representing voting rights groups, said the challengers “look forward to the next stage of this litigation.” She added: “Across the country, the administration is attempting to unlawfully shape the electorate to the will of the president and sow doubt in how our elections are run — but we will continue working to stop them at every turn.”

As the legal battles unfold, the core constitutional question remains unresolved: can a president unilaterally dictate election administration procedures that have traditionally fallen under state and congressional authority? The answer may ultimately rest with the Supreme Court.
