Rudy Giuliani denied hiding 9/11 toxic-air evidence, saying his administration “posted everything.” Mayor Zohran Mamdani’s administration released 170,000 air-quality documents; Giuliani said he was told more was known about 10 months after leaving office.
CNN reported that an October 2001 memo among the documents said health advisories caused people to return to the area either too soon, risking toxic exposure or emotional harm, or too late, causing economic hardship.
Giuliani also said the EPA initially declared the air safe. On Sept. 8, Mamdani said people got sick because leaders they trusted lied and told them the air was safe to breathe. Benjamin Chevat, executive director of 9/11 Health Watch, told the New York Post that four mayoral administrations had kept from the public, Congress and City Council for 25 years documents showing what the city knew about chemical dangers in Lower Manhattan and western Brooklyn, even as officials called the air “safe and acceptable.”
