US soldier Bowe Bergdahl, who walked away from his army unit in 2009 and was held for five years by the Taleban, is the subject of the newly released second season of popular podcast Serial.
Bergdahl opens up for the first time about the time he spent as a prisoner in Afghanistan.
"Suddenly, it really starts to sink in that I really did something bad. Or, not bad, but I really did something serious," Bergdahl says in the podcast, which was released on Thursday.
Bergdahl, now 29 years old, wandered from his army unit and was taken prisoner by the Taleban.
In 2014, he was released in a controversial prisoner exchange that freed five Guantanamo Bay detainees.
He still faces desertion charges in a US military court, which could bring a life sentence.
Republicans in the House of Representatives armed forces committee on Wednesday released a report that said US President Barack Obama had not informed Congress about the prisoner exchange in a timely manner.
The Republicans were especially critical of the release of five Guantanamo detainees to Qatar.
The first season of Serial focused on questions about the murder conviction of young Maryland man.
It was downloaded 68 million times and became one of the most popular podcasts. Observers say the second season is likely to be even more popular.
Fans of Serial have already started sharing their responces on Twitter to the podcast's return:
