The reporting

A neutral summary of the key facts most sources agree on, drawn from reporting across the political spectrum.

New York City Mayor Zohran Mamdani released more than 170,000 pages of previously undisclosed municipal records on post-Sept. 11, 2001 air quality and health risks, opening a public online portal for the files. The documents include records from multiple agencies and 68 boxes found at the Department of Environmental Protection in 2025. They show city officials had evidence of hazardous conditions, including asbestos detected nearly everywhere tested near Ground Zero, while public messaging downplayed long-term health risks. The release accompanies settlements of two lawsuits brought by 9/11 Health Watch seeking disclosure.
