Mayor Zohran Mamdani and former Mayor Rudy Giuliani shook hands at Ground Zero ahead of the annual remembrance ceremony.

Rudy Giuliani's spokesperson accuses Mayor Zohran Mamdani of scoring political points after 170,000 pages of 9/11 toxic air records were released.

Former Mayor Rudy Giuliani issued a scathing statement one day after New York City released nearly 200,000 documents related to post-9/11 air quality and health risks, suggesting city officials at the time knew of the potential environmental dangers in the days after the attacks.

According to the transcript, Todd Beamer asked the operator, Lisa, to call his wife and say that he would always love her.

The former mayor, who has launched a series of Islamophobic broadsides against Mamdani, appeared to offer words of encouragement on Friday.

He added that his election shows New Yorkers have lost sight of the city's history and what 9/11 meant. On "Finnerty" Friday, Giuliani, who was New York City's mayor on 9/11, said "large segments of New York City have forgotten" what the attacks meant.

A swell of scandals has subsumed the 82-year-old Giuliani’s once-prestigious reputation as the hard-charging Manhattan U.S. attorney credited with taking down the mob.

NPR's Michel Martin asks John Avlon, who was chief speechwriter to New York Mayor Rudy Giuliani at the time of the 9/11 attacks, for his memories of that day.
