A coalition of nine Democratic governors, led by Illinois' JB Pritzker, have urged the United States Postal Service (USPS) to withdraw a proposed rule that aims to enforce an executive order signed by President Donald Trump in March. The order directs the USCIS and SSA to create a "citizenship list" for each state, with the USPS tasked to limit mail-in ballots only to those on the lists. However, a federal judge has previously blocked Trump’s executive order, deeming it unconstitutional as states and Congress, not the president, have the authority to set election rules. The governors' letter cites this ruling and argues that the proposed rule would undermine trust in elections, disenfranchise eligible voters, and grant the USPS unilateral power to refuse mail-in ballots if a state refuses to comply with Trump’s directives. The USPS has yet to respond to requests for comment. The proposed rule was filed after a judge declined to block it due to the administration's lack of implementation steps, and legal challenges against the order continue. Both orders aim at preventing voting by non-citizens, an issue shown to be rare in studies, and Trump has also expressed concerns about mail-in voting despite using the method himself. The orders have faced criticism from postal workers, with the American Postal Workers Union president stating that their role is not voter eligibility verification but the transportation of mail.
