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.

Watson v. Republican National Committee (Amicus)
In 2020, in a nearly unanimous bipartisan vote, Mississippi joined eighteen other states in accepting mail ballots postmarked by Election Day that arrived after Election Day (in Mississippi’s case, up to five business days). This lawsuit by partisan actors seeks to disenfranchise these voters whose ballot is mailed by Election Day but—through no fault of their own—does not arrive until afterwards. In Mississippi, this harm will fall disproportionately on voters with disabilities, older voters, and other communities that rely upon absentee voting. Twisting the words and meaning of Congress, the RNC argues that three longstanding federal laws that set a uniform election day for federal races require that ballot may only be counted if they are received by election officials by Election Day. If accepted, this radical argument would not only disenfranchise thousands upon thousands of voters in Mississippi and eighteen other states, but also upend election administration in every state.

Hispanic Federation v. Byrd
Of all 50 states, Florida ranks 47th in percentage of its eligible citizens who are registered to vote. Yet, in May 2023, Florida Governor Ron DeSantis signed SB 7050, which bars any noncitizen — regardless of lawful residence status — from working or volunteering for third-party voter registration organizations (3PVROs) who register eligible Floridians to vote. In practice, the law imposes a $50,000 fine on a 3PVRO for each noncitizen who engages in voter-registration work on a 3PVRO’s behalf. This law would silence and put out of business countless community-based groups that rely on both citizens and noncitizens to help eligible voters in their communities participate in their democracy.

OCA-Greater Houston v. Paxton
Texas has growing Hispanic and Black populations that helped propel record voter turnout in the November 2020 election. The Texas Legislature responded to this increased civic participation with an omnibus election bill titled Senate Bill 1—SB 1 for short—that targeted election practices that made voting more accessible to traditionally marginalized voters like voters of color, voters with disabilities, and voters with limited English proficiency. Since 2021, SB 1 has resulted in tens of thousands of lawful votes being rejected, and it remains a threat to democracy in Texas.
