‘Shameful’ secrets: City Council leaders, firefighters demand to know why City Hall hid post-9/11 air quality reports for 25 years

The City Council leadership is demanding answers to that critical question nearly 25 years after the Sept. 11, 2001, terrorist attacks destroyed the World Trade Center, killed more than 2,800 people, and left hundreds of firefighters and other recovery workers exposed to toxins that would later take their lives.
