American Civil Liberties Union (ACLU) — Headquarters: 125 Broad Street, New York, NY

NoteThe source text explicitly lists the ACLU's National Office address as '125 Broad Street, 18th Floor, New York, NY 10004-2400'. The claim states the headquarters is at '125 Broad Street, New York, NY', which matches the street address and city/state. The source provides additional detail (18th Floor and full ZIP code 10004-2400) but does not contradict the claim. The claim's address is confirmed by the source.

NoteThe claim specifies a particular address (125 Broad Street, New York, NY) for the ACLU headquarters. While the source is from the ACLU's official 'About' page (aclu.org/about), the provided excerpt focuses on organizational history and does not include any address information. Without the source text addressing the headquarters location, the claim cannot be verified or contradicted based on this source material.
