Trump’s Executive Order on Mail-In Voting Faces Federal Blockage as Supreme Court Weighs the Case
By Drooid · · How we work
Core Event
President Donald Trump’s March 2026 Executive Order 14399 directs the United States Postal Service (USPS) to maintain a “citizenship verification list” of eligible voters and to block the delivery of any mail-in ballot that does not match that list. The USPS issued a final rule requiring states to provide voter-specific Intelligent Mail barcodes and to obtain USPS approval for ballot-envelope designs. Federal courts have repeatedly blocked the rule, and the U.S. Supreme Court is now considering a request to lift the injunction.
Background & Context
A Brookings Institution analysis finds an average mail-voting fraud rate of 0.000043 %—about four fraudulent cases per 10 million ballots—across the 2016-2022 elections. Despite these findings, the administration has pursued nationwide restrictions on mail voting ahead of the 2026 midterms, in which roughly one-third of Americans are expected to vote by mail.
Timeline
- March 2026 – Trump signs Executive Order 14399.
- August 2026 – Trump casts a mail-in ballot in Florida’s Republican primary.
- September 1, 2026 – A whistleblower statement, released by Senator Richard Blumenthal, alleges that USPS eliminated standard testing, creating a risk of “catastrophic failure.”
- September 10, 2026 – The 1st U.S. Circuit Court of Appeals rejects the administration’s request to lift the district-court injunction, calling the rule “likely unlawful” and potentially disenfranchising millions.
Data & Statistics
- Brookings: four cases of mail-voting fraud per 10 million votes.
- UCLA Voting Rights Project (April 2020) identified 31 credible impersonation cases out of a billion votes.
- One-third of Americans are projected to vote by mail in the 2026 midterms.
Official Statements & Responses
The Department of Justice called the USPS rule a “modest” mail-related regulation, but the 1st Circuit panel, composed of judges appointed by President Joe Biden, rejected that framing, noting that election-regulating authority rests with states and Congress. District Judge Indira Talwani (appointed by President Barack Obama) issued the original injunction, finding the rule would likely disenfranchise millions while offering minimal fraud mitigation.
Criticism & Opposition
- Senator Tammy Baldwin (D-WI) called the order “unconstitutional” and an attempt to “meddle in the elections.”
- Senator Richard Blumenthal (D-CT) highlighted the USPS’s rushed implementation and testing shortcuts.
- Governor Gavin Newsom (D-CA) condemned the rule as a “dangerous and un-American attack” on free elections.
- A bipartisan coalition of 99 House members, led by Congressman Chris Pappas (NH-01), filed an amicus brief urging the Supreme Court to block the rule.
- State election officials in Kentucky, North Dakota, South Dakota, Georgia, Kansas, and New Hampshire warned that late changes would “breed confusion” and erode confidence.
Conflicting Reports & Gaps
Independent analyses show that mail-in fraud is exceedingly rare and that the proposed verification system would require a federal voter database that does not yet exist. No state has announced plans to adopt the rule, and the USPS portal for voter data remains non-operational.
What’s Next
The Supreme Court, with a 6-3 conservative majority, is expected to issue a ruling on the request to lift the injunction “in the coming days.” If the Court allows the rule to proceed, states would need to redesign ballot envelopes, generate voter-specific barcodes, and upload voter data to a still-unbuilt portal before November 3, Election Day. Election officials are preparing contingency plans and urging voters to cast ballots early to avoid potential delays.
