New York City Releases 170,000 Pages of Undisclosed 9/11 Air-Quality Records

On September 8, 2026, NYC released roughly 170,000 pages of previously undisclosed documents on post-9/11 air quality and health risks. Mayor Zohran Mamdani said people got sick because "trusted leaders lied and told them they were safe to breathe in toxic air." The release comes days before the 25th anniversary of the attacks that killed 2,753.
