Army Sgt. Bowe Bergdahl’s return from POW captivity in 2014 has been plagued from the get-go with questions about what the Obama administration knew when it agreed to trade five high-ranking Taliban officers for his release.

Many have asked whether Obama and his team knew prior to the exchange that Bergdahl, who pleaded guilty last week to desertion and misbehavior before the enemy, was captured in Afghanistan in 2009 after he abandoned his post. Many have also asked whether the administration was aware of the charges that the sergeant’s desertion endangered the lives of the U.S. service members who were subsequently sent out to find him.
