Brandon Gill turns the controversy into a political argument
Representative Brandon Gill took the criticism further by placing Mamdani’s Muslim identity and democratic-socialist politics at the center of his response.
Gill argued that the sight of a Muslim mayor and progressive political figures appearing to laugh during a 9/11 ceremony would have been unimaginable to New Yorkers in 2001.
His comments transformed what might otherwise have remained a debate about etiquette and public behavior into a broader argument about how the United States has changed since the attacks.
The implication was powerful: New York in the immediate aftermath of 9/11, according to this framing, would not have accepted the presence or behavior of a politician like Mamdani at the center of the city’s memorial rituals.
But that argument raises a complicated historical question.
New York City in 2001 was not the same city it is today. Nor was America.
Mamdani was a child in New York on September 11, 2001. According to The Associated Press, he grew up in a post-9/11 city in which Muslims did not always feel welcome. He later became a U.S. citizen and entered New York politics, eventually becoming the city's first Muslim mayor.
His presence at Ground Zero therefore carries a significance that would have been almost impossible to imagine in the immediate aftermath of the attacks.
But that significance can be interpreted in two very different ways.
Critics can see it as evidence of how dramatically New York's political culture has changed.
Supporters can see it as evidence of the city's capacity to incorporate Muslim Americans into the civic mainstream without treating an entire religion as responsible for the actions of al-Qaida terrorists.
Those competing interpretations are at the heart of the controversy.
Mamdani's Muslim identity has become inseparable from the political debate
The political significance of Mamdani's presence at the memorial cannot be separated from the fact that he is Muslim.
That reality has already been a major source of controversy surrounding his political career.
The AP reported earlier this year that Republican rhetoric directed at Mamdani repeatedly invoked the September 11 attacks and his Muslim identity. Mamdani himself argued that such rhetoric was troubling not merely because of the words used, but because of the actions and attitudes that can accompany it.
The issue is particularly sensitive because the aftermath of 9/11 produced a documented rise in suspicion, discrimination and hostility toward Muslim Americans.
Reuters noted in its coverage of the 25th anniversary that the attacks reshaped American perceptions of Muslims and that Muslim Americans and immigrants from Muslim-majority countries faced increased prejudice and hate crimes after 2001.
That history complicates the argument that Mamdani's Muslim identity itself should be treated as politically relevant to whether he belongs at Ground Zero.
The attackers were members of al-Qaida, a terrorist organization whose ideology does not represent Muslims generally. Millions of Muslim Americans lived through the attacks, mourned victims, served as first responders, joined the armed forces, and participated in the national response.
Indeed, one of the striking features of the 25th-anniversary ceremony was the effort by some participants to reject the use of 9/11 as a weapon against Muslims.
The AP reported that Michael Massaroli, whose father was killed in the attacks, used his time at the podium to criticize people who use the tragedy to spread hatred toward Muslims and others.
That perspective provides important context for the Mamdani controversy.
A city transformed by September 11
Mamdani's appearance at Ground Zero also reflects how dramatically New York has changed over the past quarter-century.
In 2001, the city was dealing with immediate trauma. The World Trade Center had been destroyed. Thousands were dead or missing. First responders were still searching through the ruins. The smell of smoke and burning material remained over Lower Manhattan.
The political and emotional atmosphere was fundamentally different.
Today, the attacks remain deeply painful, but the city has developed rituals, institutions and public memories around the tragedy. Ground Zero has become a permanent memorial rather than an active disaster site.
The National September 11 Memorial now occupies the footprints of the Twin Towers. The names of the victims are permanently inscribed around the memorial pools. Visitors arrive from around the world to pay their respects.
The Guardian's reporting ahead of the anniversary described Ground Zero as a place that has become a destination for mourning, reflection and remembrance for people with both direct and indirect connections to the attacks.
The 25th anniversary therefore represented both remembrance and generational change.
People who were adults in 2001 are now grandparents. Children who were not yet born have grown up learning about 9/11 through history books, museums, family stories and annual ceremonies.
Mamdani belongs to that younger generation.
His presence at the memorial could therefore be interpreted not as a rejection of the city's 9/11 memory, but as a reflection of the fact that the generation shaped by the post-9/11 period is now occupying positions of political power.
