"Today the nation mourns the loss of 4 American diplomats, including Ambassador to Libya Chris Stevens, in a rogue act of senseless violence.
"Like John Granville of Buffalo, who lost his life in 2008 while working for USAID in Sudan, these Americans answered a call of service and devoted their lives each and every day to improve the safety and prosperity of those in a foreign nation.
"These Americans bravely risked their own safety to improve the lives of those in societies that were not their own. That is the American spirit, and we are eternally grateful for their inspiring service. Their good work will never be forgotten."
