U.S. Postal Service proposes rule requiring states to submit mail-ballot voter lists, implementing Trump's elections executive order

On May 29, 2026, the U.S. Postal Service issued a notice of proposed rulemaking, "Ballot Mail for Federal Elections" (FR Doc. 2026-10968), published in the Federal Register on June 2 with a 30-day public comment period. The rule would amend the Domestic Mail Manual to require state and local election officials to submit to USPS the names and ballot barcodes of voters who request mail-in or absentee ballots in federal general, special, and runoff elections. USPS would compile that data into state-specific "Mail-In and Absentee Participation Lists" through a new "Federal Ballot Mail Portal," and would deliver ballots only to voters who appear on those lists or whose envelopes meet a federally specified design.

The rulemaking is the Postal Service's implementation of Executive Order 14399, which President Trump signed on March 31, 2026 directing USPS to take on this gatekeeping role (recorded separately as the executive order itself). The constitutional objection is the same one that attaches to the order: the Elections Clause (Art. I, Sec. 4) places the "Times, Places and Manner" of federal elections with the states, subject to override by Congress — not by the president or an executive agency acting on his instruction. By proposing to condition ballot delivery on data states must surrender to a federal portal, the executive branch asserts authority over election administration that the Constitution does not give it, bypassing both the states and Congress.

The act recorded here is that assertion, which is complete: the agency has formally proposed the rule pursuant to the President's order. The rule is not yet final — it may be modified, withdrawn, or enjoined after the comment period closes in early July 2026 — and the voter-level harms it threatens (disenfranchisement of eligible voters whose records do not match, and a chilling effect on mail-ballot use) are contingent on finalization and enforcement. Those downstream effects are why voter-suppression is mapped as a secondary risk rather than an accomplished harm; the primary abuse is the executive overreach embodied in the attempt itself.

The proposal drew immediate legal challenge. On June 3, 2026, the NAACP Legal Defense Fund and Public Citizen Litigation Group filed a motion in federal court (NAACP v. USPS) to enforce a December 2021 settlement in which USPS committed to prioritizing the timely delivery of election mail through 2028, asking the court to bar USPS from proceeding with the rule and to rule on an expedited basis.
