Senate approves ambassador to Afghanistan, 9 others

"On behalf of the International Security Assistance Force and U.S. Forces-Afghanistan, I offer our congratulations to Ambassador Cunningham on his confirmation as the new Ambassador to Afghanistan," Allen said. "I am honored to continue working with the ambassador in his new position as he helps build the strategic partnership between the U.S. and Afghanistan that will ultimately strengthen Afghan sovereignty, security and prosperity."

Cunningham's appointment comes at a critical time, as U.S. forces begin to withdraw from Afghanistan after 11 years of war. He'll also be responsible for overseeing preparations for the 2014 elections, which the United States sees as a crucial test of whether the country can function without U.S. support.
