Obama leads moment of silence for 9/11

President Obama led a moment of silence at the White House Wednesday morning, 12 years after the 9/11 attacks that so changed the United States.

Bells tolled and a military bugler played taps as the president and first lady Michelle Obama, joined by members of the White House staff, stood silent on the South Lawn. The moment of silence began at 8:46 a.m, the time at which the first hijacked plane hit the World Trade Center building in New York City. Vice President Biden and wife Jill also participated in the memorial ceremony. The White House flags are at half-mast today. Later this morning, Obama attends a September 11 Observance Ceremony at the Pentagon, also struck by a hijacked plane that fateful day. This afternoon, the president participates in a service project, part of the the National Day of Service and Remembrance in honor of the 9/11 victims.
