October 22, 2026 NEW YORK, Decades of relentless legal battles, fierce activism, and secret court settlements have finally forced open the vault on one of the most guarded chapters in American history.

Mayor Zohran Mamdani’s administration released a massive trove of 40,000 previously confidential documents related to the September 11, 2001 terrorist attacks. This stunning wave of disclosures brings the public archive to over 60,000 documents across more than 200,000 pages, shining a harsh light on decisions made in the dark days following Ground Zero.

What Did They Know? The Deadly Secret of Ground Zero Air

The records, published through the city’s September 11th records portal, are the direct result of a high-stakes Freedom of Information Law (FOIL) battle waged by 9/11 Health Watch, a prominent advocate group for survivors and first responders.

Prior document releases under the settlement exposed disturbing internal communications regarding lethal air quality, dust toxicity, and health risks in Lower Manhattan while thousands of workers and residents were encouraged to return to the area.

Key findings already uncovered from early tranches include:

• February 2002 Warning: An internal city memo explicitly warned that municipal leaders were failing to adequately inform the public about severe, ongoing health hazards.

• May 2002 Media Scrubbing: Offical notes revealed cleanup coordinators actively worked to eliminate the word "risk" from letters sent to the public regarding environmental safety.

"What we have seen after a review of the first tranche of 170,000 released documents is a disturbing record that, even when the problems and hazards were realized, the City, the State and the Federal government did not change course and deal with them head-on," stated Benjamin Chevat, executive director of 9/11 Health Watch.

A Promise of Full Transparency

The newly released materials represent the second major installment under the legal settlement, with additional tranches scheduled to hit the public database in the coming months.

"Our commitment to honoring the victims of the horrific terror attacks of Sept. 11 and delivering accountability and transparency to survivors cannot begin or end on the anniversary," Mayor Mamdani announced.
