President Donald Trump is set to observe Friday’s 25th anniversary of the Sept. 11 attacks by attending a ceremony at the Pentagon commemorating the lives lost when al-Qaida militants hijacked planes and killed nearly 3,000 people in three locations, upending American foreign policy and national security.

The president, who is originally from New York, last attended the ground zero ceremony there in 2024. Vice President JD Vance is set to attend the New York observance alongside former presidents, while other administration officials will go to the ceremony in Shanksville, Pennsylvania.

At a Tuesday event at the Ellipse just outside the White House, Trump vowed to “never forget” victims, noting that the Sept. 11 attacks were one of few moments in history that "divide time into really what came before and after."

Traveling for months across the country as part of the Steel Across America tour, the beam was to be in New York for a procession Friday retracing the steps of fallen New York City firefighter Stephen Siller. On Wednesday, Trump issued a proclamation that marked Friday as “Patriot Day 2026,” recounting the chronology of the 2001 day on which “the peace of our Nation was shattered” and calling his administration “unwavering in its commitment to ensure that our Nation is defended by the strongest and most lethal military the world has ever known.” The Republican midterms convention on Thursday night marked the 25th anniversary of the terrorist attacks with families onstage in Dallas and firefighters in uniform as the song “Ave Maria” was played. The names of the victims appeared on a screen and a bell was rung to commemorate the loss of firefighters.
