President Barack Obama spent the afternoon at Andrews Air Force Base, Friday, to honor U.S. Ambassador Chris Stevens and three other Americans as their remains returned home to the United States.
Obama was joined by Vice President Joe Biden and Secretary of State Hillary Clinton for the solemn ceremony.
He said the four caskets, draped with the American flag, serve as a reminder of the danger and sacrifice they faced.
"They knew the danger, and they accepted it," Obama said. "They didn't simply embrace the American ideal. They lived it."
The president also assured that despite the tragedy, the United States will never back down for what it stands for or "retreat from the world."
"This work, and the men and women who risk their lives to do it, are at the heart of what makes America great and good," Clinton added. "So we will wipe away our tears, stiffen our spines, and face the future undaunted."
Ambassador Stevens was killed this week during an attack on the U.S. consulate in Libya, along with Sean Smith, Glen A. Doherty, and Tyrone S. Woods.
"Greater love hath no man than this, that a man lay down his life for his friends," Obama said, quoting scripture. "May God watch over your families and all who love them."
