The American Civil Liberties Union (ACLU) focuses on defending and preserving individual rights and liberties as outlined in the U.S. Constitution. It engages in legal advocacy, public education, and lobbying to protect civil rights, including freedom of speech, privacy, and equality. The ACLU assists individuals and communities, particularly marginalized groups like immigrants, LGBTQ+ individuals, and racial minorities, who face government overreach and discrimination. Unlike many organizations, the ACLU operates primarily on donations, grants, and membership fees, which fund its legal cases and advocacy campaigns. Its strong brand helps attract financial support, and it also sells merchandise to further its mission. The ACLU aims to ensure that civil liberties are upheld for everyone in the United States.
