'Lone Survivor' Marcus Luttrell on Bergdahl: Clearly he has a lot of explaining to do

Former Navy SEAL Marcus Luttrell knows what it’s like to be trapped behind enemy lines. In 2005 he was part of a covert raid in Afghanistan. He was the only member of the mission to make it out alive. Nineteen U.S. troops died, including some who were trying to rescue Luttrell's team. Luttrell discussed the idea of a prisoner swap with Anderson:

"When I did get captured, the only thing I held onto was the fact that my teammates were going to come get me. Period."
