Quick Summary

Richard Clarke, a member of the National Security Council, warned Secretary of State Condoleezza Rice about the risk of an imminent major terrorist attack in June 2001, but she expressed skepticism and accused him of sensationalizing Osama bin Laden. Little more than a month later, on 9/11, Rice informed President Bush that the World Trade Center had been hit by hijacked airliners, prompting Bush to leave the Emma E. Booker Elementary School in Sarasota, Florida, and board Air Force One. The plane was then targeted by terrorists, according to investigative journalist Jeffrey Robinson's book "Ash and Honor: The Untold 368 Minutes of 9/11". The article does not report on the specifics of what happened next, but notes that the situation worsened when word arrived that the plane carrying Bush was also a target.

Story summary

On the 25th anniversary of the September 11 attacks, New York City's first Muslim mayor, Zohran Mamdani, faces controversy over his decision to attend memorial events despite calls from some victims' families and former Mayor Rudy Giuliani for him to stay away. Mamdani, who lost an older brother in the attacks, insists on honoring those affected by reading out names at Ground Zero. Meanwhile, nearly 110,000 signatures have been collected through a petition urging Mamdani not to attend, citing concerns over his past associations and appointments that some see as conflicting with the solemnity of the event. Despite this opposition, Mamdani is moving forward with plans to release more than 170,000 pages of documents related to air quality around Ground Zero in the months following 9/11, aiming to provide transparency on what the city knew about toxic conditions and how they handled it.

Narrative

When the nation came under attack, the president was in Sarasota, Fla., visiting the Emma E. Booker Elementary School for what the author calls “a media stunt before sixteen second graders, designed to highlight a new education initiative.” By the time Rice’s ominous call came through, Eddie Marinzel and Dave Wilkinson, the two men leading Bush’s Presidential Protective Division that day, had already decided to get Bush on Air Force One and off the ground.
