Newly released documents reveal that New York City officials downplayed the risks of toxic air following the 9/11 attacks, despite evidence of widespread contamination.

• 170,000 documents show asbestos was found "nearly everywhere" tested near Ground Zero.
• New York City Mayor Zohran Mamdani stated that "leaders they trusted lied" about public safety.
• The document release, spurred by a lawsuit from 9/11 Health Watch, aims to provide transparency about what the city knew regarding the toxic air and when.
