New York City Shares Hidden Files About 9/11 Air Safety

New York City made public about 170,000 pages of secret files on how dirty the air was after 9/11 and the health dangers it posed. Mayor Zohran Mamdani said people got sick because "trusted leaders lied and told them they were safe to breathe in toxic air." The release comes days before the 25th anniversary of the attacks that killed 2,753.
