Ceremonies are being held Friday at the 9/11 Memorial in New York, the Pentagon in Virginia, and the Flight 93 National Memorial in Pennsylvania to mark the 25th anniversary of the September 11 attacks, which killed nearly 3,000 people. Officials, elected leaders, and family members are reflecting on the day and its aftermath as names are read and tributes are offered at each site. President Donald Trump is expected to attend the Pentagon ceremony, while former presidents George W. Bush, Bill Clinton, Barack Obama, and Joe Biden are expected in New York. At the Flight 93 Memorial, the reading of names is scheduled for 10:03 a.m. ET, the time the plane crashed after passengers fought the hijackers. Across the country, the anniversary is being marked as a day of remembrance for the victims, first responders, and those affected by the attacks.
