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.

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.

ACLU v. DOD – FOIA Case Seeking Biden Administration’s Presidential Policy Memorandum
In October 2022, the Biden administration confirmed the existence of the White House’s latest set of policy rules governing the United States’ use of lethal force outside of recognized battlefields abroad. These new rules are known as the “Presidential Policy Memorandum (PPM).” The administration made the partially-redacted PPM public in response to the latest in a series of ACLU lawsuits to force transparency about the U.S. government’s secretive, unlawful, and controversial use of lethal force abroad, including through the use of drones.
