Brookings Institution AI and Emerging Technology Initiative — Headquarters: Washington, DC

Note: The claim specifies the headquarters of the 'Brookings Institution AI and Emerging Technology Initiative' specifically, not the Brookings Institution as a whole. The source text only provides information about the main Brookings Institution's headquarters location. There is no mention in the provided source text of an 'AI and Emerging Technology Initiative' or whether it has a separate headquarters. The address matches the main institution's address, but without confirmation that this specific initiative is headquartered at that location (as opposed to being a program within the main institution), the claim cannot be verified from this source alone.

Note: The source text explicitly states that the Brookings Institution's headquarters is located at 1775 Massachusetts Avenue, N.W. in Washington, D.C., which exactly matches the claim. The address and location are confirmed in the infobox section of the Wikipedia article.
