FOIA Case Seeking the Trump Administration’s Legal Justification for Deadly Boat Strikes
The Department of Justice’s Office of Legal Counsel (“OLC”) authored a legal opinion that reportedly claims to justify the Trump administration’s illegal lethal strikes on civilians in boats in the Caribbean Sea and eastern Pacific Ocean. Media reports indicate that, in addition to claiming that the strikes are lawful acts in an alleged “armed conflict” with unspecified drug cartels, the OLC opinion also purports to immunize personnel who authorized or took part in the strikes from future criminal prosecution. Because the public deserves to know how our government is justifying these illegal strikes, and why they think the people who carried them out should not be held accountable, the ACLU is seeking immediate release of the OLC legal opinion and related documents pursuant to the Freedom of Information Act.

Racial Justice
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.

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.

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.

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.

Aubry McMahon v. World Vision, Inc.
On October 28, 2024, the ACLU and ACLU of Washington filed an amicus brief in the U.S. Court of Appeals for the Ninth Circuit supporting affirmance of a Washington district court decision holding that a religiously affiliated nonprofit organization violated Title VII and the Washington State antidiscrimination law when it rescinded a hiring candidate’s job offer because she is a woman married to a person of the same sex. Should the Ninth Circuit accept the organization’s First Amendment defense—that religious organizations can discriminate on any basis so long as it is grounded in their religious belief—it would gut employment protections for LGBTQ individuals and pave the way for religious organizations to discriminate on the basis of not only sex, sexual orientation, and gender identity but also other protected characteristics like race, color, and national origin.

American Civil Liberties Union of South Carolina v. State Election Commission
The South Carolina Department of Motor Vehicles (SCDMV) has unlawfully denied young, eligible South Carolinians the opportunity to register to vote. Under South Carolina law, individuals who are 17 years old may register to vote and vote in primary elections so long as they (1) will turn 18 on or before the next general election, and (2) otherwise meet the qualifications for voting. An administrative error in the SCDMV's processes, however has stopped the Department from transmitting the proper paperwork to complete all registration information to the South Carolina Elections Commission. As a result, thousands of young voters who did everything right and should have been registered to vote have not been added to the state's voter rolls in the runup to the 2024 general election. ACLU and ACLU of South Carolina sued, asking the court to ensure that these new voters are registered and properly notified in time for them to vote in the November 2024 election.

Spung v. Evnen
Less than four months before the November 2024 presidential election, the Nebraska Secretary of State issued a directive embracing a non-binding opinion issued by the state Attorney General that would essentially reinstate permanent felony disenfranchisement and re-disenfranchise tens of thousands of Nebraska citizens. This directive is violative of both the Nebraska Constitution and several state statutes, and urgent relief is needed to avoid mass disenfranchisement of an entire class of Nebraska citizens.

The directive deprives everyone who is lawfully assisting another voter from using a drop box, and mandates that drop boxes may be used only by voters who are returning their own ballot. We filed an amicus brief to explain the harsh, unnecessary burdens this directive will impose on voters and election officials alike.
