Army Sgt. Bowe Bergdahl is predicted to soon plead guilty to desertion and misbehavior before the enemy in a case that has dragged on for years.
Taliban terrorists reportedly kidnapped Bergdahl after he left his post and held him captive for about five years until the former USA president authorized the controversial exchange in 2014.
After five years in Taliban captivity, Bergdahl was released in exchange for five Taliban detainees who had been held at Guantánamo Bay.
President Trump has called Bergdahl a "horrible double crosser" who "ought to have been executed".
Bergdahl's attorneys have argued that Trump's presumption of guilt has made it impossible for the former Army sergeant to get a fair trial, writing in a January court filing that the president had "transformed his rallies into a televised traveling lynch mob".
He has said he was confined, kept oblivious, beaten and affixed to a bed.
At the time, he was 23 years old and was held captive by the Taliban for roughly 5 years.
Eugene Fidell, Bergdahl's lawyer, declined to comment on the report.
Bergdahl's decision to plead guilty rather than face trial marks another twist in an eight-year drama that caused the nation to wrestle with hard questions of loyalty, negotiating with hostage takers and America's commitment not to leave its troops behind.
However, in December 2009, the Taliban released a second video showing him in good health as he delivered a lengthy statement criticizing the US military.
Recordings soon developed indicating Bergdahl in imprisonment by the Taliban, and the United States watched him with drones, spies and satellites as in the background negotiations played out in fits and begins.
"We're exhausted of Sgt. Bergdahl, who's a traitor, a no-good traitor, who should have been executed", Trump said at a Las Vegas rally in 2015.
Bergdahl's explanation for leaving his post is that he wanted to draw attention to problems in his unit. But the judge, Army Col. Jeffrey R. Nance, rejected the request.
The defense separately argued Trump's scathing criticism unfairly swayed the case. Investigators said Bergdahl suffered from schizotypal personality disorder when he left his post. The Associated Press (AP) cited two sources who said the disgraced soldier will enter the plea rather than face trial for deserting his post in Afghanistan back in 2009. The misbehavior charge has rarely been used in recent decades, though there were hundreds of cases during World War II.
