NYC withheld air quality data after 9/11 attacks, Jon Stewart says in testimony to officials

Comedian and 9/11 first responder advocate Jon Stewart testified before New York City officials, stating that the city knew about poor air quality in the weeks following the terrorist attacks but chose to suppress the information rather than take protective measures. Stewart characterized the city's decision as prioritizing a return to business as usual over the health and safety of first responders and residents exposed to contaminated air.

๐Ÿงญ In Context

Stewart has been a consistent advocate for 9/11 first responders and survivors regarding long-term health effects from exposure to debris and air contaminants at Ground Zero. According to reporting on his advocacy, he has repeatedly pressured city and federal officials to acknowledge and compensate health consequences tied to the post-attack environment. This testimony represents a continuation of that public campaign.
