ARLINGTON, Virginia (CNN) - President Obama called on all Americans on Monday to remember U.S. troops who died in the service of their country.
The president issued his call after participating at the annual Memorial Day wreath-laying ceremony at Arlington National Cemetery's Tomb of the Unknowns.
The men and women buried at Arlington "waged war so that we may know peace," Obama said.
"They were willing to give up everything for the defense of our freedom [and] were willing to sacrifice all for their country. ... They are the best of America."
