To begin two days of events commemorating the tenth anniversary of 9/11, President Obama and First Lady Obama visited Arlington National Cemetery today to pay their respects to members of the military. Holding hands as they walked through the rows of graves, the President and Mrs. Obama visited Section 60 in the southeast portion of the cemetery, which is reserved for service members killed in the Iraq and Afghanistan wars.
"On the occasion of the tenth anniversary of 9/11, the President believes that it is important for all Americans to honor those who have served since 9/11, to remember those lives we have lost, and to support their families," a White House official said.

The President and First Lady's schedule for 9/11 commemorations is here.
The motorcade left the White House about noon for the visit to Arlington, and arrived back at the White House at 12:11 to pick up the First Daughters.

President Obama's weekly address is here, and devoted to 9/11. He sent an e-mail from the White House this morning, urging Americans to participate in community service projects.
