President Trump issued a March executive order directing the Postal Service to adopt new rules governing mail-in ballots. The order required states to provide lists of eligible mail ballot recipients to the Postal Service and use agency-approved envelopes with unique barcodes. The Postal Service could refuse to send or deliver ballots that did not comply with the new standards.
U.S. District Judge Carl Nichols of Washington, D.C. also ruled against the Trump administration's mail voting restrictions on September 13, joining Judge Talwani's ruling blocking the rule.
Conservative Justice Brett Kavanaugh filed a concurrence in the Supreme Court ruling stating that while the government had "at least a fair prospect" of success defending the mail voting plan, implementation so close to the 2026 election day would be "arbitrary and capricious" and election officials "do not have sufficient time to reasonably implement the rule."
U.S. District Judge Indira Talwani of the Boston-based court issued a preliminary injunction on September 4 blocking the new mail voting rule. Talwani found that the rule likely violated the U.S. Constitution, under which states administer elections, and determined it would be impossible for states to comply given the rapidly approaching midterm elections.
The Boston-based 1st U.S. Circuit Court of Appeals refused to put Judge Talwani's order on hold. The court stated that the rule "will likely result in the disenfranchisement of millions of voters across the country while providing minimal – if any – gains in combating voter fraud."
The U.S. Supreme Court rejected the Trump administration's request to enforce new Postal Service rules restricting mail-in ballots ahead of the 2026 midterm elections. The court upheld a preliminary injunction issued by U.S. District Judge Indira Talwani that blocked the rule. The unsigned order stated: "The government is unlikely to succeed on the merits of its challenge to the district court's preliminary injunction."
Justice Samuel Alito, joined by Justice Clarence Thomas, dissented from the Supreme Court's decision. Alito argued that the Postal Service "has broad authority to regulate the mail" and likely does have the power to enforce Trump's restrictions. Alito also contended that the plaintiff states should not benefit from timing created by their own legal challenges.
Alabama, North Carolina, and Wisconsin began sending mail ballots to voters in the week prior to the Supreme Court ruling while the new Trump administration system was still not active. Election officials stated there was simply no way to carry out a complete overhaul of mail voting procedures in the weeks before the midterm elections.
A coalition of 23 states, mostly Democratic-governed, along with Washington D.C. and multiple voting rights groups including the ACLU and NAACP filed lawsuits challenging the new Postal Service mail voting rule. The challengers argued that the U.S. Constitution gives no authority for the president to issue orders governing election administration.
Justices Samuel Alito and Clarence Thomas were the only dissenters in the Supreme Court's decision to block the new mail-in ballot rules. They argued that the Postal Service has broad authority to regulate the mail and compared the states' legal challenge to a 'Hail Mary' pass unlikely to succeed.
The League of Women Voters and other Democratic-aligned groups praised the Supreme Court's decision to block the new mail-in ballot rules. The League's CEO, Celina Stewart, characterized the Trump administration's attempt as an 'extraordinary attempt to interfere with voting in all 50 states' and stated that voters should not be 'caught in the middle of political power warfare.'
Justice Brett Kavanaugh issued a concurring opinion stating that while the new Postal Service rule likely falls within the agency's authority, applying it in the 2026 elections would be arbitrary and capricious because state and local election officials lacked sufficient time to implement it before the elections. He signaled the rule could potentially be legal in the future.
President Donald Trump posted on Truth Social on September 16, 2026, criticizing the Supreme Court's decision to block his administration's mail-in ballot rules. Trump called the decision a 'disaster' and blamed the court system for taking too long to rule. He praised Justices Alito and Thomas as 'legends' and criticized his three appointees—Justices Kavanaugh, Barrett, and Gorsuch—saying they were not the justices he had interviewed.
Analysis shows that mail ballots accounted for between 74.7 percent and 91.3 percent of statewide turnout in four closely contested House districts in 2026: Colorado's 8th District (91.3 percent), Arizona's 1st and 6th Districts (74.7 percent), and California's 22nd District (80.8 percent). These districts are rated as Toss-Ups by election forecasters.
In his statement criticizing the Supreme Court mail-ballot decision, President Trump referenced prior Supreme Court rulings that went against his administration policies on tariffs and birthright citizenship. Trump stated the decision would 'cost me dearly for years to come' and expressed his obligation as President to criticize the court.
The Supreme Court maintained a block on new U.S. Postal Service regulations that would have required federal ballot mail to use approved envelopes with election-mail logos, unique barcodes for each voter, and state submission of voter information to a USPS portal. The decision came on September 14, 2026, in response to the Trump administration's appeal of a federal court block issued in late August.
The U.S. Supreme Court ruled in an emergency order on Monday that the Trump administration's proposed restrictions on mail-in voting would likely lose in court. The administration had sought to require states to provide voter lists to the U.S. Postal Service to check for fraud before delivering mail ballots, but state election officials argued there was insufficient time to implement the changes before the November 3 midterm elections and that their existing systems were secure and accurate.
The Supreme Court overturned a 50-year-old rule that capped how much political parties could spend in coordination with candidates. The rule had been enacted by Congress in 1974 as part of post-Watergate reforms and upheld by the Supreme Court in 2001. Justice Brett Kavanaugh wrote for the 6-3 majority that the rule violated First Amendment free-speech protections, allowing both parties to participate more freely in the political process.
In a 2024 decision, the Supreme Court's conservative majority ruled that former presidents are presumptively entitled to immunity for all official acts. This decision allowed Trump to run for reelection without facing threat of a criminal trial that year.
A report by the Brookings Institution published in 2025 found that mail voting fraud occurred in only about four cases out of every 10 million mail ballots cast. Approximately one-third of voters use mail ballots, and mail voting has already begun in some states for the midterm elections.
