President Trump on Thursday marked the 24th anniversary of the Sept. 11 attacks by visiting the Pentagon memorial, where he laid a wreath and paid tribute to those killed.

“This morning, we recall the light of America’s best and bravest and the love that they showed in their final moments,” Trump said. “In their memory we make a solemn pledge and a noble promise. We will honor always our great heroes.”

The president was joined by first lady Melania Trump at the memorial, which honors the 184 people who were killed when a plane crashed into the building on Sept. 11.

Trump used his remarks to recognize multiple instances of bravery from those on 9/11, including Army Sergeant First Class Steve Workman, who was at the Pentagon that day and helped get others out of the building.

“On that fateful day, savage monsters attacked the very symbols of our civilization. Yet here in Virginia, and in New York, and in the skies over Pennsylvania, Americans did not hesitate,” Trump said. “They stood on their feet, and they showed the world that we will never yield, we will never bend, we will never give up, and our great American flag will never, ever fail.”

The president and first lady laid a wreath inside the Pentagon Chapel after the remembrance ceremony.

Pete Hegseth, whose title was recently changed to secretary of War, and Chairman of the Joint Chiefs of Staff Dan Caine also delivered remarks at the Pentagon.

Trump last year marked the anniversary of 9/11 at Ground Zero in New York City. Vice President Vance was set to be at Ground Zero on Thursday, but he instead flew to Utah after his close friend and conservative activist Charlie Kirk was killed there.

The president is scheduled to fly to New York City later Thursday to attend the Yankees game in the evening.
