The U.S. is remembering lives taken and others reshaped by 9/11. Wednesday marks an anniversary laced with presidential campaign politics. Sept. 11 is the day when hijacked-plane attacks that killed nearly 3,000 people in New York, the Pentagon and Pennsylvania in 2001. The date falls in the thick of the presidential election season every four years, and it comes at an especially pointed moment this time. Vice President Kamala Harris and former President Donald Trump both are expected to attend the same 9/11 observances in New York and Pennsylvania. It’s not yet clear whether the Democratic and Republican nominees will cross paths. But they could encounter each other at a somber Sept. 11 ceremony hours after facing off on a debate stage for the first time.
