Obama: America Has a ‘Sacred Rule’ Not To Leave Servicemen Behind

"The United States has always had a pretty sacred rule, and that is we don't leave our men or women in uniform behind. And that dates back to the early days of our revolution. We have consulted with Congress for quite some time about the possibility that we might need to execute a prisoner exchange in order to recover Sergeant Bergdahl. We saw an opportunity. We were concerned about Sergeant Bergdahl's health. We had the cooperation of the Qataris to execute an exchange, and we seized that opportunity."
