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.

The ACLU, the ACLU of Florida, the Southern Poverty Law Center, and their partners represent CAIR and CAIR-Florida in two federal lawsuits challenging Governor DeSantis’s unconstitutional and baseless designation of the nonprofits as “terrorist.” The lawsuits allege violations of CAIR and CAIR-Florida’s rights under the First Amendment and the due process clause of the Fourteenth Amendment.

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 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.

Zyst v. Miller
Following the Oregon Department of Corrections’ unconstitutional treatment of a transgender prisoner, a habeas court ordered her removal from segregated housing, an individualized gender-affirming care assessment, a psychiatric evaluation, and identification of an appropriate cellmate. However, the Oregon Court of Appeals reversed the psychiatric-evaluation and cellmate orders, finding them “too attenuated” to qualify as habeas relief. The ACLU’s State Supreme Court Initiative, alongside the ACLU of Oregon, joined an amicus brief by the law firm Sugerman Dahab arguing that habeas courts have broad discretion to remedy violations and resulting harms. The brief explains that the Court of Appeals’ “close connection” test unduly constricts habeas relief, and which should be construed to encompass not only the need to halt ongoing constitutional violations, but also the need to mitigate various harms that may arise from those violations.

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.

United States v. DeMarinis
The Department of Justice (“DOJ”) sued Maryland demanding the release of its full, unredacted voter file, which includes the highly sensitive and personal data of every voter in the state. This suit appears to be part of DOJ’s effort to build a national voter database without congressional authorization, improperly question the validity of state voter rolls, and intimidate eligible voters in Maryland and around the country.

Marquez v. State of Montana
Amelia Marquez is transgender woman and life-long Montanan. John Doe is a transgender man who was born in Montana, but currently lives out of state. Both wish to correct the sex marker on their birth certificates to reflect who they are. However, a law enacted in 2021, Montana Senate Bill 280, sought to prohibit transgender individuals born in Montana from correcting the sex marker listed on their birth certificate without obtaining a court order indicating that their “sex . . . has been changed by surgical procedure.” The ACLU, the ACLU of Montana, and Nixon Peabody LLP have sued, claiming that SB 280 violates the equal protection and due process clauses of the Montana State Constitution.

Salles, et al. v. National Institutes of Health, et al.
Salles, et al. v. National Institutes of Health, et al. is a class action lawsuit challenging the censorship and termination of federally funded research by the National Institutes of Health (NIH). While ongoing litigation in APHA v. NIH successfully resulted in the reinstatement of hundreds of grants, NIH’s current policies continue to target viewpoints it opposes, threatening research because the government dislikes what it thinks the researchers believe or are likely to say, and continue to violate governing statutes and regulations. This is stymieing critical public health research, particularly related to climate change, the starkest health disparities including those faced by communities of color and LGBTQ+ populations, and other areas.
