NYC Mayor Mamdani releases 9/11 records showing officials misled New Yorkers about air quality around Ground Zero

Key Points:

• New York City has released over 170,000 pages of previously undisclosed records revealing that officials knew the air quality around Ground Zero after the September 11 attacks was unsafe despite public assurances to the contrary.
• Mayor Zohran Mamdani highlighted that nearly 25 years later, more people have died from 9/11-related illnesses than were killed on the day of the attacks, with at least 140,000 enrolled in the World Trade Center Health Program and 49,000 diagnosed with related cancers.
• The released documents include key internal memos, such as the "Harding Memo," which showed city officials anticipated thousands of lawsuits due to toxic air exposure and considered legislative measures to limit liability.
• Advocacy efforts led to the inclusion of cancer coverage in the health program in 2012, after initial exclusion in 2011, following studies showing elevated cancer rates among first responders.
• A searchable portal will provide free public access to these documents, which were discovered last year and are being released ahead of the 25th anniversary of the attacks, addressing long-standing calls for transparency from survivors and first responders.
