NYC to publish 9/11 toxic air documents; mayor cites legal liability

New York City Mayor Zohran Mamdani announced the online release of tens of thousands of documents detailing what the city knew about toxic air around Ground Zero after 9/11 and how it acted to limit legal responsibility. The release follows over 9,400 illness-related deaths linked to the attacks, in addition to the 2,977 killed. The move signals potential legal and political fallout over decades-old exposure claims.
