State Board of Election Commissioners v. Mississippi State Conference of the NAACP
Mississippi has a growing Black population, which is already the largest Black population percentage of any state in the country. Yet. Black Mississippians continue to be significantly under-represented in the state legislature, as Mississippi’s latest districting maps fail to reflect the reality of the state’s changing demographics. During the 2022 redistricting process, the Mississippi legislature refused to create any new districts where Black voters have a chance to elect their preferred representative. The current district lines therefore dilute the voting power of Black Mississippians and continue to deprive them of political representation that is responsive to their needs and concerns, including severe disparities in education and healthcare.

Louisiana v. Callais (Callais v. Landry)
Whether the congressional map Louisiana adopted to cure a Voting Rights Act violation in Robinson v. Ardoin is itself unlawful as a gerrymander.

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.

Wise v. Missouri
In unprecedented fashion, the State of Missouri has redrawn the district lines used for electing members of Congress for a second time this decade. These new district lines are gerrymandered and will harm political representation for all Missourians, particularly Black residents in Kansas City, who have been divided along racial lines.

Allen v. Milligan
Whether Alabama’s congressional districts violate Section 2 of the Voting Rights Act because they discriminate against Black voters. We succeeded in winning a new map for 2024 elections which, for the first time, has two congressional district that provide Black voters a fair opportunity to elect candidates of their choosing despite multiple attempts by Alabama to stop us at the Supreme Court. Despite this win, Alabama is still defending its discriminatory map, and a trial was held in February 2025 to determine the map for the rest of the decade.
In May 2025, a federal court ruled that Alabama's 2023 congressional map both violates Section 2 of the Voting Rights Act and was enacted by the Alabama Legislature with racially discriminatory intent.

White v. Mississippi State Board of Elections
District lines used to elect Mississippi’s Supreme Court have gone unchanged for more than 35 years. We’re suing because this dilutes the voting strength of Black residents in state Supreme Court elections, in violation of the Voting Rights Act and the U.S. Constitution.

ACLU v. NSA – FOIA Lawsuit Seeking Records About the NSA’s Use of Artificial Intelligence
The National Security Agency (NSA)—one of the country’s biggest intelligence agencies—has been rapidly developing and deploying AI, but we still know remarkably little about this transformation and its impact on civil rights and civil liberties. As the NSA increasingly integrates AI into its daily operations and some of its most profound decisions, it has left the public largely in the dark about how it is using AI and what safeguards, if any, are in place to protect everyday Americans. In March 2024, the ACLU filed a request under the Freedom of Information Act seeking the release of recently completed studies, roadmaps, and reports that show how the NSA is using AI and how those tools affect people’s privacy and civil liberties. When the government failed to release the documents sought in our FOIA request, we filed suit in April 2024 to challenge this unjustified secrecy and compel public disclosure of these documents.

Iowa Migrant Movement for Justice v. Bird
Civil rights groups filed a federal lawsuit to block SF 2340, one of the worst, most far-reaching immigration laws ever passed in the state of Iowa. The measure conflicts with existing federal law and will have a number of dramatic consequences for Iowans. It creates new crimes for anyone in Iowa, including a child, who has reentered the country after being deported, even if that person is now authorized to be in the U.S.

Crystal Mason v. State of Texas
Crystal Mason thought she was performing her civic duty by filling out a provisional ballot in the 2016 election. She didn't know it would land her a five-year prison sentence, upending her family and the life she had built. At the time, Ms. Mason was on federal supervised release, a preliminary period of freedom for individuals who have served their full time of incarceration in federal prison. Ms. Mason didn’t know, and nobody told her, that the state considered her ineligible to vote while on supervised release. Because her name didn’t appear on voter rolls, she filed a provisional ballot, consistent with federal law. The state never counted her ballot but has still sought to send her to prison for an innocent mistake.
