President Obama and First Lady Michelle made a detour on their way home from speaking at this morning's 9/11 anniversary ceremony at the Pentagon by stopping by Arlington National Cemetery.
The first couple visited Section 60, an area of the cemetery where casualties of the wars in Iraq and Afghanistan are laid to rest. While there, he placed ten presidential challenge coins on a large gravestone which honors the 10 members of the military and DEA who were killed in a helicopter crash in Afghanistan on October 26, 2009.
Challenge coins are "medallions bearing insignia passed out by commanders as motivation or to honor achievement." President Obama has given them out to veterans he has met at different events in his presidency. He also left challenge coins at the memorials of the victims of the Ft. Hood shootings in 2009.
This was the president's fourth trip to Section 60 since taking office, including a stop last year to commemorate a decade since the deadly attacks.
