The United States commemorated the 25th anniversary of the September 11, 2001 terrorist attacks, with ceremonies and photo retrospectives marking the day hijackers flew planes into the World Trade Center and the Pentagon, killing thousands. Coverage included profiles such as Dan Chung, CEO of Fred Alger Management, who survived the attack by chance and was tasked with rebuilding the firm after 35 colleagues died. Separately, 25 years after the attacks, the U.S. government has begun rolling back some post-9/11 security measures, including certain airport screening protocols such as liquid restrictions and gate access rules, reflecting evolving threat assessments and technology.
