New York City releases documents about air quality after 9/11

• New York City has released previously unseen documents raising concerns about air quality in Manhattan in the aftermath of the 9/11 attacks, Mayor Zohran Mamdani announced on Tuesday.
• The documents from 25 years ago suggest that officials had concerns about toxic air after the World Trade Center towers collapsed, while the public was being reassured the environment at the site, known as Ground Zero, was safe.
• "People got sick because the leaders they trusted lied and told them they were safe to breathe in toxic air," Mamdani said at a news conference, surrounded by survivors.
