President Donald Trump led several commemorations to mark the 25th anniversary of the September 11 terrorist attacks. At the White House Ellipse, an event organized in part by the Tunnel to Towers Foundation, Trump proclaimed the day as Patriot Day and renewed the national vow to ‘Never Forget.’ The ceremony featured a 21-foot steel beam from the World Trade Center South Tower as part of the ‘Steel Across America’ exhibition and included tributes to fallen heroes such as Welles Crowther and Jeffrey Palazzo.

During the Ellipse event, Trump emphasized American resilience, stating the nation possesses a strength that ‘no fire can consume.’ He also vowed to use ‘all its power’ to prevent future large-scale attacks. However, he faced scrutiny for repeating claims that he led a construction workforce to Ground Zero and was evacuated by firefighters—assertions that contradict archival records and previous statements placing him at Trump Tower.

On September 11, a memorial service was held at the Pentagon. Trump described the attacks as a ‘moment of massive and terrible evil’ and called for national unity, recalling how Americans stood together as one family following the tragedy. He linked the anniversary to current geopolitical tensions, specifically the struggle to ensure Iran never acquires nuclear weapons. Defense Secretary Pete Hegseth also spoke, noting that U.S. forces have spent the last six months targeting state sponsors of terrorism. Former Secretary of State Condoleezza Rice attended, reflecting on the attacks and noting that NATO invoked Article 5 for the first time in its history to support the United States.
