Fighting Voter Suppression
League of Women Voters of Massachusetts v. Trump
On March 31, 2026, President Trump issued a sweeping Executive Order titled "Ensuring Citizen Verification and Integrity in Federal Elections," seeking once again to seize control of election administration from Congress and the states. The Order directs federal agencies to compile lists of U.S. citizens and transmit them to states before every election, directs the U.S. Postal Service -- an independent agency established by Congress -- to create a list of "approved" mail voters, and instructs USPS to refuse to deliver ballots from voters not on that federally created list. If implemented, the Order would threaten the ability of millions of eligible citizens to cast their ballots, particularly military members, overseas citizens, the elderly, recently naturalized citizens, and voters with disabilities who rely on mail voting.

Fighting Voter Suppression
League of Women Voters Education Fund v. Trump
On March 25, 2025, in a sweeping and unprecedented Executive Order, President Trump attempted to usurp the power to regulate federal elections from Congress and the States. Among other things, the Executive Order directs the Election Assistance Commission—an agency that Congress specifically established to be bipartisan and independent—to require voters to show a passport or other citizenship documentation in order to register to vote in federal elections. If implemented, the Executive Order would threaten the ability of millions of eligible Americans to register and vote and upend the administration of federal elections.
On behalf of leading voter registration organizations and advocacy organizations, the ACLU and co-counsel filed a lawsuit to block the Executive Order as an unconstitutional power grab.

Montana Federation of Public Employees v. Montana
Representing Western Native Voice and four sovereign tribal nations in Montana, the American Civil Liberties Union, ACLU of Montana, and Native American Rights Fund (NARF) challenged the latest in a line of Montana laws that hinder Native American participation in the state’s electoral process — SB 490, which drastically limits access to Election Day voter registration (EDR) in Montana. These laws violate a number of provisions in the Montana Constitution: the right to vote, equal protection, and due process.

Common Cause v. U.S. Department of Justice
The U.S. Department of Justice has launched an unprecedented and unlawful effort to invade the privacy of millions of American voters and threaten their right to vote. It has demanded that every state and the District of Columbia turn over their entire voter database, including Social Security Numbers, political party affiliation, and voter participation history. And at least a dozen states have complied, submitting their voters’ information for federal review. But the Department of Justice has no authority to dictate when a voter registration should be cancelled, and we are suing to stop the federal government’s overreach and ensure that voters’ information remains secure and free from unlawful interference.

United States v. Adams
The Trump administration's Department of Justice has taken Kentucky to court in an attempt to obtain sensitive, non-public information from the state's voter registration database — including Social Security numbers, driver's license numbers, dates of birth, and home addresses. This lawsuit is one of nearly three dozen similar actions filed against states across the country, and reporting suggests the underlying goal is to construct an unauthorized federal voter database and use error-prone data-matching tools to target registered voters — including naturalized citizens — for potential removal from the rolls.
