The ACLU is a non-profit organization dedicated to working daily in courts, legislatures and communities across America to defend and preserve the individual rights and liberties that the Constitution and laws of the United States guarantee everyone in this country. Since 1920, we have been dedicated to defending and expanding the civil liberties of all Americans. The ACLU has staffed offices in all 50 states, along with Washington D.C. and Puerto Rico. Our work is sustained entirely by the membership dues and donations of our nearly 500,000 active members nationwide. Across the country, the ACLU has more than 200 staff attorneys who collaborate with thousands of volunteer attorneys in countless civil liberties cases each year, making the ACLU the largest public interest law firm in the nation. The ACLU appears before the U.S. Supreme Court more than any other organization except the U.S. Department of Justice.
