A coalition of Democratic governors, led by Illinois Governor JB Pritzker, have petitioned the United States Postal Service (USPS) to rescind a proposed rule aimed at implementing an executive order signed by President Donald Trump in March. The order directed federal agencies to create voter lists for each state and limit mail-in ballots to those on these lists. However, a federal judge has already blocked this order, deeming it unconstitutional as only states and Congress possess the authority to establish election rules. The governors' letter emphasized that the proposed rule would undermine trust in elections, complicate voting processes, arbitrarily disenfranchise voters, and encroach upon state constitutional powers regarding free and fair elections. The USPS has yet to comment on the matter. The proposed rule was filed after a judge declined to block it, as the administration had not yet taken steps to implement the order at that time. Democratic and civil rights groups have appealed this ruling, while postal workers have also expressed concerns about the order's potential implications for their duties. This is the second election-related executive order Trump has signed since his return to office, following a previous order, also blocked by courts, requiring citizenship proof for voter registration. Despite claims of widespread mail voting fraud, studies and investigations have shown such incidents to be rare.
