Why It Matters
The release follows a lawsuit by 9/11 Health Watch regarding the city's handling of toxic air exposure information after the 2001 attacks.
New York City Mayor Zohran Mamdani released more than 170,000 pages of internal records Tuesday that show officials misled people about the safety of the air around Ground Zero after the September 11 terror attacks.
“People got sick because the leaders they trusted lied and told them they were safe to breathe in toxic air,” Mamdani said during a news conference, according to CNN.
The move came just days before the U.S. is set to commemorate the 25th anniversary of the al Qaeda hijackings that killed nearly 3,000 people when passenger planes toppled the World Trade Center’s Twin Towers, damaged the Pentagon and crashed near Shanksville, Pennsylvania.
Comedian and activist Jon Stewart, an outspoken supporter of first responders who were sickened while searching for remains at Ground Zero, also spoke at Mamdani’s City Hall news conference.
“There was poison in the air, and on the ground, and in the window sills, and in your air conditioners, and covering your pets and your clothes, and it stayed there for months,” he said. “Everyone knew. Now it’s very clear that the city knew as well.”
The documents released by Mamdani are available free of charge on a searchable city website, with Corporation Counsel Steven Banks saying in a message there that other records will be added “on a rolling basis in the coming months.”
The records include the so-called Harding Memo, which was sent to then-Deputy Mayor Robert Harding with the title “Legislative Alternatives to Limit the City’s Liability Relating to 9/11/01.”
“It provides insight into the City’s consideration of potential legal and legislative responses in the aftermath of the attacks, including concerns about the prospect of substantial litigation arising from toxic exposure and the adequacy of safety equipment,” Banks said.
The release of the records resolved a lawsuit filed by the advocacy group 9/11 Health Watch, according to The New York Times, which got early access to the documents.
But the revelations in them could lead to new or amended lawsuits from people who suffered 9/11-related ailments, and bolster claims by people seeking payments from the federal September 11th Victim Compensation Fund, the NYT said.
