Mamdani announces free portal with 170,000 pages of 9/11 records

New York Mayor Zohran Mamdani says his administration is releasing city records concerning the lasting health effects of the September 11 attacks.

New York Mayor Zohran Mamdani announced a free online portal for September 11 documents as the United States marked 25 years since the attacks. In a post on X, he said his administration was releasing an initial 170,000 pages and making them available to the public.

Mamdani said New Yorkers had spent years seeking city records about the attacks' lasting health effects and had been denied access. He alleged that the newly released documents show city officials knew conditions around Ground Zero were dangerous but misled residents. That characterization is the mayor's account of what the records establish.

The mayor linked the release to accountability for families and first responders. He said people continue to live with illnesses connected to the attacks, describing difficulties breathing and repeated medical visits, and pledged to honor those lost through greater honesty about the city's response.
