Details of the document release
The release follows a legal agreement with 9/11 Health Watch, a victims’ advocacy group that sued to compel the city to make the information public. Mayor Mamdani stated that the documents demonstrate what the city knew about toxic air around Ground Zero, the timing of that knowledge, and the steps taken by officials to limit liability.

According to a federal medical monitoring programme, more than 9,400 people have died from illnesses linked to exposure to the area in the years since the attacks. Benjamin Chevat, director of 9/11 Health Watch, stated that four different mayoral administrations withheld information while simultaneously telling the public that the air was safe.
