Obama, in brief remarks, praised Chris Stevens, the U.S. ambassador to Libya; Glen Doherty and Tyrone Woods, former Navy SEALs working for a private contractor; and Sean Smith, an Air Force veteran working for the State Department.
"Four Americans, four patriots -- they loved this country and they chose to serve it, and served it well. They had a mission and they believed in it. They knew the danger and they accepted it," Obama said. "They didn't simply embrace the American ideal, they lived it. They embodied it -- the courage, the hope and, yes, the idealism, that fundamental American belief that we can leave this world a little better than before."
