American Civil Liberties Union
The ACLU, a nonprofit, nonpartisan organization, was founded to ensure the promise of the Bill of Rights and to expand its reach to people historically denied its protections. For nearly 100 years, the ACLU has been our nation's guardian of liberty, working in courts, legislatures, and communities to defend and preserve the individual rights and liberties that the Constitution and the laws of the United States guarantee everyone in this country. The ACLU is now a nationwide organization with a 50-state network of staffed affiliate offices filing cases in both state and federal courts. We appear before the Supreme Court more than any other organization except the Department of Justice.
