The anniversary of the September 11 attacks unfolded this year along two tracks: a solemn commemoration led from Washington and a renewed examination in New York of what officials knew about the air in Lower Manhattan after the towers fell.

At the Ellipse near the White House, President Trump marked the day by honoring the victims and pledging to "never forget." He awarded a posthumous Presidential Medal of Freedom to Welles Crowther, the young equities trader known as the "man in the red bandanna." Crowther, then 24, helped guide survivors out of the South Tower before he died in its collapse. Witnesses later described a man wearing a red bandanna over his face who led people to safety and returned upstairs to find more.

While Washington observed the ceremony, attention in New York turned to the question of the air quality that lingered around Ground Zero in the weeks and months after the attacks. New York City Mayor Zohran Mamdani said officials had misled residents about the safety of that air, and his administration released roughly 170,000 pages of documents that he said support the account.

The records, reviewed by several news organizations, detail concerns about contamination in Lower Manhattan during the recovery period. The full contents of the release, and what they establish about official knowledge at the time, remain the subject of ongoing review. Conservative commentators cautioned against drawing sweeping conclusions, arguing that the science on the long-term health effects of the site was uncertain in 2001 and that the document release should be weighed carefully rather than treated as settled proof of a cover-up.

The anniversary also drew attention to the federal programs that serve people who became ill after exposure at Ground Zero. The Social Security Administration, following reported delays in processing disability claims tied to 9/11-related illnesses, said it would move to address the backlog and carry out its responsibilities to affected claimants.

More than two decades after the attacks, the twin threads of the day capture how the events of 2001 continue to reverberate. The commemoration honored those who died on the day itself, including first responders and civilians. The document release and the health-claims debate concern the thousands who have fallen ill in the years since, and the lasting questions about the government's handling of the aftermath.

The attacks of September 11, 2001, killed nearly 3,000 people in New York, at the Pentagon and in a field in Pennsylvania. Health programs established afterward continue to track and treat illnesses linked to the toxic dust and debris of the World Trade Center site.
