# US 9/11 25th anniversary commemorations > Live situation record from CLSTR: https://clstr.news/situations/us-911-25th-anniversary-commemorations > Updated: 2026-09-10T19:31:01.000Z. Sources: 104. Developments: 4. President Donald Trump has confirmed he will attend a commemoration ceremony at the Pentagon to mark the 25th anniversary of the September 11 terrorist attacks, rather than attending the memorial service at Ground Zero in New York City. This decision follows a policy maintained by the National September 11 Memorial & Museum since 2012, which prohibits politicians from delivering speeches at the New York ceremony to ensure the event remains nonpartisan. While Trump observes the anniversary at the Pentagon, Vice President JD Vance is expected to represent the administration at the New York City ceremony. Trump has sparked controversy by claiming that firefighters forcibly removed him from a building in Manhattan that was at risk of collapsing. He alleged he was near the United States Steel Building, now known as One Liberty Plaza, which he described as ‘creaking’ and appearing as though it might fall on him. He claimed two firefighters ‘literally grabbed me by the arm’ and carried him to safety. While reports indicate Trump was located kilometers away from Ground Zero on the day of the attacks, Trump has since clarified on Truth Social that he was not at the site on the day of the collapse but arrived shortly thereafter with a construction crew. To defend his version of events, Trump has cited his former head of security, Matthew Calamari, as a witness. In response to media scrutiny, Trump has demanded retractions from New York Magazine and reporter Maggie Haberman. Adding to the dispute, Trump’s nephew, Fred Trump, has publicly contested these narratives. Fred challenged the claim that Donald Trump sent construction crews to assist at Ground Zero, noting that the only available employees would have been secretarial and accounting staff. He also disputed the accounts regarding the building’s instability and the subsequent evacuation. ## Timeline ### 2026-09-10: U.S. leaders mark 25th anniversary of 9/11 attacks in New York Former U.S. presidents and New York officials gathered at the 9/11 Memorial for its 25th anniversary.
