The U.S. is remembering the lives taken and those reshaped by 9/11, marking an anniversary laced this year with presidential campaign politics.
Sept. 11 — the date when hijacked plane attacks killed nearly 3,000 people in 2001 — falls in the thick of the presidential election season every four years, and it comes at an especially pointed moment this time.
Fresh off their first-ever debate Tuesday night, Vice President Kamala Harris and former President Donald Trump are both expected to attend 9/11 observances at the World Trade Center in New York and the Flight 93 National Memorial in Pennsylvania.
Then-senators and presidential campaign rivals John McCain and Barack Obama made a visible effort to put politics aside on the 2008 anniversary. They visited ground zero together to pay their respects and lay flowers in a reflecting pool at what was then still a pit.
It’s not yet clear whether Harris and Trump even will cross paths. If they do, it would be an extraordinary encounter at a somber ceremony hours after they faced off on the debate stage.
Regardless of the campaign calendar, organizers of anniversary ceremonies have long taken pains to try to keep the focus on victims. For years, politicians have been only observers at ground zero observances, with the microphone going instead to relatives who read victims’ names aloud.
“You’re around the people that are feeling the grief, feeling proud or sad — what it’s all about that day, and what these loved ones meant to you. It’s not political,” said Melissa Tarasiewicz, who lost her father, New York City firefighter Allan Tarasiewicz.
President Joe Biden, on the last Sept. 11 of his term and likely his half-century political career, is headed with Harris to the ceremonies in New York, in Pennsylvania and at the Pentagon, the three sites where commercial jets crashed after al-Qaida operatives took them over on Sept. 11, 2001.
Officials later concluded that the aircraft that crashed near rural Shanksville, Pennsylvania, was headed toward Washington. It went down after crew members and passengers tried to wrest control from the hijackers.

The attacks killed 2,977 people and left thousands of bereaved relatives and scarred survivors. The planes carved a gash in the Pentagon, the U.S. military headquarters, and brought down the trade center's twin towers, which were among the world's tallest buildings.
The catastrophe also altered U.S. foreign policy, domestic security practices and the mindset of many Americans who had not previously felt vulnerable to attacks by foreign extremists.
Effects rippled around the world and through generations as the U.S. responded by leading a “ Global War on Terrorism,” which included invasions of Afghanistan and Iraq. Those operations killed hundreds of thousands of Afghans and Iraqis and thousands of American troops, and Afghanistan became the site of the United States' longest war.
As the complex legacy of 9/11 continues to evolve, communities around the country have developed remembrance traditions that range from laying wreaths to displaying flags, from marches to police radio messages. Volunteer projects also mark the anniversary, which Congress has titled both Patriot Day and a National Day of Service and Remembrance.
At ground zero, presidents and other officeholders read poems, parts of the Declaration of Independence and other texts during the first several anniversaries.
But that ended after the National Sept. 11 Memorial and Museum decided in 2012 to limit the ceremony to relatives reading victims’ names. Then-Mayor Michael Bloomberg was board chairman at the time and still is.
Politicians and candidates still have been able to attend the event. Many do, especially New Yorkers who held office during the attacks, such as former Secretary of State Hillary Clinton, who was then a U.S. senator.
She and Trump overlapped at the ground zero 9/11 remembrance in 2016, and it became a fraught chapter in the narrative of that year's presidential campaign.
Clinton, then the Democratic nominee, abruptly left the ceremony, stumbled while awaiting her motorcade and later disclosed that she had been diagnosed with pneumonia a couple of days earlier. The episode stirred fresh attention to her health, which Trump had been questioning for months.
To be sure, victims' family members occasionally send their own political messages at the ceremony, where readers generally make brief remarks after finishing their assigned set of names.
Some relatives have used the forum to bemoan Americans' divisions, exhort leaders to prioritize national security, acknowledge the casualties of the war on terror, complain that officials are politicizing 9/11 and even criticize individual officeholders.
But most readers stick to tributes and personal reflections. Increasingly they come from children and young adults who were born after the attacks killed a parent, grandparent, aunt or uncle.
“Even though I never got to meet you, I feel like I’ve known you forever,” Annabella Sanchez said last year of her grandfather, Edward Joseph Papa. “We will always remember and honor you, every day.
“We love you, Grandpa Eddie.”
