American Civil Liberties Union (ACLU) — Website: https://www.aclu.org/

Note: The Wikidata excerpt provided discusses various properties of the ACLU (inception date, founders, leadership, affiliations, assets, etc.) but does not include a 'website' or 'official website' field that would confirm or contradict the claimed URL of https://www.aclu.org/. While the source references several URLs (archive.org links, action.aclu.org, aclu.org document links), these are incidental references within other contexts and do not constitute an explicit statement of the organization's official website. To verify this claim, one would need a source that explicitly states the ACLU's official website URL in a dedicated field.

Note: The source is a Wikidata entry for the ACLU (Q21637) that lists various properties like inception date, founders, leadership, and affiliations. However, the excerpt provided does not include a 'website' or 'official website' property that would directly confirm or contradict the claimed URL. While https://www.aclu.org/ appears in some reference URLs within the text, this is not the same as an explicit statement of the organization's official website in the Wikidata structured data. To verify this claim, one would need to see the actual 'website' property field on the Wikidata page, which is not shown in this excerpt.
