The League of Women Voters and a coalition of voting rights organizations have filed a federal lawsuit challengin a recent executive order issued by Donald Trump that seeks to reshape mail-in voting nationwide.

Filed in U.S. District Court in Massachusetts, the lawsuit argues that the order unlawfully interferes with election administation—authority that the U.S. Constitution reserves to Congress and the states.

The executive order directs federal agencies to create a national list of eligible voters and would require the United States Postal Service to limit the delivery of mail ballots only to individuals on that list. Voting rights advocates warn that federal databases are often incomplete or outdated, raising the risk that eligible voters could be wrongly excluded from voting by mail.

The lawsuit contends that the order transforms the Postal Service from a neutral mail carrier into a gatekeeper of ballot access—an action plaintiffs argue is both unconstitutional and unworkable. It also raises concerns about potential voter disenfranchisement, particularly for populations that rely heavily on mail voting.

The League is joined in the case by national and international voting advocacy groups, including the U.S. Vote Foundation and the Association of Americans Resident Overseas. Together, the coalition is seeking to block implementation of the order and affirm that election rules must remain in the hands of states and Congress.

The case is part of a broader wave of legal challenges from voting rights organizations and elected officials, all asserting that the executive branch lacks authority to unilaterally change how Americans vote.
