Army Sergeant Bowe Bergdahl is speaking out for the first time in the NPR podcast, Serial.
He talked about the night he walked away from his post in Afghanistan in 2009 and was captured by the Taliban.
“I'm going: 'Good grief, I’m in over my head.' Suddenly, it really starts to sink in that I really did something bad. Or, not bad, but I really did something serious,” he said.
Bergdahl compared himself to movie spy Jason Bourne, claiming he walked away to warn high-level Army commanders about problems within his platoon.
“Doing what I did was me saying I am like, I don't know, Jason Bourne. All those guys out there who go to the movies and watch those movies, they all want to be that, but I wanted to prove that I was that," he said.
INSIDE EDITION spoke to Bergdahl's lawyer Eugene R. Fidell who called Trump "the defamer-in-chief" and displayed every time Trump has defamed his client.
