Monday on CNN's "The Lead," host Jake Tapper reported on the growing backlash from U.S. military members to the Obama administration for the deal that resulted in the swap of five terrorism suspects for U.S. Army Sgt. Bowe Bergdahl, a prisoner of war who the Taliban had held hostage since 2009. U.S. Army Sgt. Josh Korder joined Tapper under the threat of possible repercussions from the military to discuss Bergdahl's behavior while they served together in Blackfoot company, second platoon in Afghanistan. "He is at best a deserter, and at worst a traitor," Korder said of Bergdahl.
