How US leaders remembered the 25th anniversary of the 9/11 attacks

A quarter-century after the attacks on September 11, 2001, officials across the United States have taken part in tributes and memorials to honour the 2,977 victims and those who risked their lives as part of the rescue efforts.

The incident is considered the deadliest “terrorist” attack in US history.

Four planes were hijacked. Two crashed into the World Trade Center, causing its Twin Towers to collapse. A third struck the Pentagon outside Washington, DC. And the fourth plummeted into a field in Shanksville, Pennsylvania, after passengers and crew rose against their attackers.

Through social media messages, public speeches and appearances at ceremonies, US leaders on Friday took different approaches to remembering the lives of the thousands who perished on the fateful day.

Here’s what they said:

US President Donald Trump

US President Donald Trump chose to stay in Washington, DC, to observe the 25th anniversary.

During the attacks, 184 people died near the capital when American Airlines Flight 77 struck the Pentagon, the headquarters of the US military.

Trump opted not to attend a Friday ceremony at the World Trade Center site in New York, where all his living presidential predecessors were in attendance.

His vice president, JD Vance, travelled to New York instead. The ceremony at the World Trade Center has a policy of not allowing political speeches.

In his remarks at the Pentagon, Trump described what happened as “true evil”. He also paid tribute to those who died in the attacks.

“We will honour their lives, we will cherish their beautiful memories, and we will protect this country and its freedoms for every future generation,” Trump said.

The president also praised US troops as he appeared to link the 9/11 attacks with his administration’s war against Iran.

“We will never, ever forget. That’s why we fight today. We don’t have a choice. There can only be victory,” Trump said.

“We salute the service members working right now to ensure the world’s number one sponsor of terror – the Islamic Republic of Iran – will never, ever have a nuclear weapon,” he later added.

US Secretary of Defense Pete Hegseth

US Defense Secretary Pete Hegseth also spoke at the Pentagon, delivering his remarks shortly before Trump’s.

He warned the audience to practice “eternal vigilance” against what he called continued threats.

“There are still enemies who hate us. Every day, enemies plot to curb our power and kill our citizens, including from Islamic terrorists abroad and at home,” he said.

He proceeded to seemingly use the 9/11 attacks as justification for the US-Israeli war against Iran, which started on February 28.

“Over the past six months, we have laid waste to the world’s most prolific state sponsor of terrorism,” Hegseth said, referring to Iran. “Our warriors have fought an Islamic theocracy that has wished us death for nearly half a century, that cheered on 9/11.”

He went on to claim that the US military has destroyed Iran’s defences and that the US controls the Strait of Hormuz, a vital waterway for international trade.

Iran has stopped commercial traffic through the strait since the start of the war.

“We’re still sending terrorists where they belong, to hell, and tankers to the bottom of the ocean where they belong,” Hegseth said. “And we’re ensuring that Iran will never have a nuclear weapon. The economic pressure tightens every day. We control the strait. We will finish this fight.”

New York City Mayor Zohran Mamdani

New York City Mayor Zohran Mamdani attended the New York memorial service, alongside the city’s former mayor, Rudy Giuliani, who led the city through the attacks.

Before the event started, Giuliani shook hands with the mayor, despite previously calling on Mamdani not to attend the event.

Mamdani, the city’s first Muslim mayor, had recently come under fire from some conservative politicians and victims’ family members who said his presence at the memorial would offend them.

A Change.org petition garnered more than 100,000 signatures from those who wished to express concern about Mamdani’s participation.

Like all politicians attending the service at the National September 11 Memorial, Mamdani was not permitted to speak.

Instead, the mayor released a video on social media remembering those who were killed and challenging the public to honour their memory by doing good works.

“Twenty-five years later, we have a sacred obligation to those who were stolen from us. To care for one another as they cared for strangers. To live lives worthy of the sacrifices they made. And to build a city worthy of their courage. A city where we run toward one another,” Mamdani said.

“That is how we’ll remember.”

On Tuesday, Mamdani also released a trove of previously undisclosed documents suggesting city officials tried to downplay – or even mislead – first residents about the dangerous air quality following the attacks.

US Senate candidate Abdul El-Sayed

Democratic Senate candidate Abdul El-Sayed took to the social media platform X to honour the lives lost during what he described as a “cruel act of terror”.

El-Sayed is locked in a tight midterm race in Michigan against his Republican opponent, former US Representative Mike Rogers.

Michigan’s open Senate seat is considered a must-win seat for Democrats, if they hope to take back control of the US Senate.

Rogers has sought to create controversy over El-Sayed’s past comments about the September 11 attacks. He has pointed to audio of El-Sayed reportedly saying, “9/11 scarred our country in profound ways, but what we did after 9/11 scarred millions of other people.”

During the Republican Party’s first-ever midterm convention in Dallas, Texas, on Thursday, Rogers blasted El-Sayed, who is Muslim, for being sympathetic to terrorists. He also sought to highlight El-Sayed’s links to left-wing internet commentator Hasan Piker.

“I never imagined that, 25 years after 9/11, I would be running against somebody who campaigns with Hasan Piker, who thinks America deserved it,” Rogers said. “Yep, but here we are.”

On Friday, however, El-Sayed used his social media post to push back against Rogers’s attacks.

“Nothing can justify the murder of innocent civilians. Nothing,” El-Sayed wrote.

He also called on Americans to help build a country that was “more inclusive, more empowering, more just” in tribute to the lives lost.

“They didn’t just attack America that day. They attacked the idea of America,” El-Sayed said of the 19 al-Qaeda hijackers who participated in the attacks.

“The notion of a nation brought together by ideals where it doesn’t matter how you pray or if you pray at all. A place where freedom and commitment to justice bind us, even if at times we struggle to fully realise it.”
