The U.S. Postal Service has halted all development on a computer system central to President Donald Trump’s 2026 mail-voting restrictions, Postmaster General David Steiner confirmed on Thursday. The decision follows a Supreme Court ruling Monday that upheld a nationwide injunction blocking the agency’s rule, leaving the policy inoperative for the upcoming midterm elections.
Steiner stated in an Associated Press interview that the USPS is not proceeding with any work on the system due to the legal hold. “There’s an injunction so we’re not doing anything,” he said. The Supreme Court’s refusal to lift the injunction—issued by U.S. District Judge Indira Talwani of Massachusetts on Sept. 4—means states will continue processing mail ballots under existing procedures.
Part 1: Immediate Action & Core Facts
Supreme Court blocks Postal Service rule
The high court’s 7-2 decision rejected Trump’s March 31 executive order, which sought to tighten mail-voting protocols by requiring postal verification of ballots and voter data compliance. The ruling, joined by Trump-appointed Justices Neil Gorsuch, Brett Kavanaugh, and Amy Coney Barrett, determined there was insufficient time to implement the changes before the 2026 elections. Justice Kavanaugh, in a concurring opinion, suggested the Postal Service may still have authority to regulate ballot handling but agreed the timeline was impractical.
Postal Service confirms system freeze
Steiner, who took over as postmaster general in 2025 amid financial and operational challenges, emphasized the USPS’s role as an independent agency focused on execution rather than policy. He declined to endorse or criticize Trump’s order, stating his concerns were operational. “I don’t get to decide what rules that are put on us that I decide to accept or not accept,” Steiner said. “I looked at it more from the execution side.”
Part 2: Deeper Dive & Context
Legal and Political Fallout
Trump responded to the ruling with criticism on social media, targeting the three justices he appointed for joining the majority. “They are not the people I interviewed,” he wrote. The White House had argued the Postal Service could enforce ballot security measures, but the Supreme Court’s decision underscored constitutional limits on presidential authority over elections, which are administered by states under the Constitution.
Congressional and Whistleblower Responses
Sen. Richard Blumenthal (D-Conn.) had raised concerns in an Aug. 31 letter to Steiner, citing a whistleblower’s claim that the portal’s implementation was “perilously rushed and potentially unlawful.” Steiner acknowledged reading the letter but expressed confidence in the IT team’s work, noting the project was completed rapidly. “My personal opinion is it was a monumental task and I’m very proud of our IT department,” he said.
Background: The Postal Service’s Role
The USPS’s involvement in the dispute stems from Trump’s 2026 executive order, which directed the agency to verify mail ballots and reject those lacking pre-approved barcodes or from non-compliant states. The rule was published Aug. 26, prompting immediate legal challenges. Judge Talwani’s Sept. 4 injunction extended a temporary restraining order issued Aug. 27, halting enforcement nationwide.
Operational and Financial Context
Steiner has spent the past year navigating the USPS’s financial struggles, describing the agency as facing a “liquidity crisis.” He continues to advocate for congressional action to address long-term funding issues, separate from the election-related dispute. The Postal Service’s neutrality in the matter was repeatedly emphasized by Steiner, who framed the agency’s actions as driven by legal constraints rather than political alignment.
