A coalition of Democratic governors led by Illinois Governor JB Pritzker has requested the United States Postal Service (USPS) to rescind a proposed rule that aligns with an executive order signed by President Donald Trump in March. The order sought to establish a federal voter list and limit mail-in ballots to those on the list, a move deemed unconstitutional by a federal judge as only states and Congress have the power to set election rules. The governors' letter, joined by counterparts from California, Connecticut, Minnesota, New York, Pennsylvania, Rhode Island, Washington, and Wisconsin, argues that the proposed rule would jeopardize trust in elections, disenfranchise eligible voters, and infringe on states' constitutional roles in ensuring fair elections. The USPS has yet to respond to requests for comment regarding the proposal. The proposal was filed after a judge declined to block the executive order because the administration had not initiated its implementation at the time. Legal challenges against the order are ongoing, with the potential for an appeal of the ruling. The executive order has faced resistance from postal workers, who view their role as delivering mail rather than verifying voter eligibility. This is the second election-related executive order signed by Trump since his return to office; the first, also blocked by the courts, aimed to require documented proof of citizenship for voter registration. Despite Trump's claims of widespread fraud associated with mail voting, studies and investigations have shown that instances of such fraud are rare. The popularity of mail voting has grown among both Democrats and Republicans alike. A 2025 report by the Brookings Institution found that cases of mail voting fraud were minimal, approximately four per 10 million mail ballots.
