Americans for Responsible Innovation — Headquarters: Washington, DC

Note: The source text explicitly states 'Americans for Responsible Innovation Washington, DC' in the organization listing section. This directly confirms that the organization's headquarters is in Washington, DC, matching the claim exactly.

Note: While the URL and additional context suggest Washington, DC as the headquarters, the actual source text excerpt provided does not contain a clear statement confirming the headquarters location. The excerpt appears to be incomplete (cuts off mid-sentence in the 'About Us' section). To properly verify this claim, the complete source text would need to explicitly state the headquarters location. The URL structure and metadata are suggestive but not definitive proof of the claim itself appearing in the source content.
