U.S. Army Private Bowe Bergdahl watches as one of his captors displays his identity tag to the camera at an unknown location in Afghanistan, in this still image taken from video on July 19, 2009. The family of Bergdahl says it is frustrated that more than a year of covert U.S. diplomacy has been unable to free their son and is urging the Obama administration to push harder for his release. Bob Bergdahl, speaking out about his son's case after a long silence, said in May 2012 he hopes U.S. negotiators will press ahead with efforts to set in motion a chain of events intended in part to lead to the release of his son, believed to be held in Pakistan since he went missing in eastern Afghanistan in June 2009.
