Mayor Mamdani accuses past city leaders of covering up Ground Zero air toxicity

Mayor Mamdani used a City Hall briefing to launch a public portal containing 170,000 pages of documents about the aftermath of the 2001 attacks, asserting that city leaders misled the public about hazardous air at the disaster zone. He singled out former mayor Rudy Giuliani and every subsequent mayor for allegedly covering up the truth, linking the concealment to the high number of first-responders who have later died from related diseases.

The mayor’s remarks were accompanied by a petition signed by more than 102,000 individuals, many of whom lost loved ones, demanding he refrain from attending the memorial ceremony. Opponents note that air-quality oversight falls under the Environmental Protection Agency and that any federal concealment would span multiple presidential administrations. They also suggest Mamdani’s timing is politically motivated, pointing to his recent controversial statements and associations. The release of the documents adds to ongoing debates over health compensation for responders and the legacy of the disaster’s environmental impact.
