President Obama and First Lady Michelle Obama visited Arlington National Cemetery on Wednesday, where they honored Veterans' Day and made a surprise visit to the area reserved for troops killed in Iraq and Afghanistan, walking among the grave sites and talking to mourners.
"To all of them -- to our veterans, to the fallen and to their families -- there is no tribute, no commemoration, no praise that can truly match the magnitude of your service and your sacrifice," he said.
Obama pledged he would do right by all veterans and families, saying: "America will not let you down."
