General Mark Milley continues to review the circumstances surrounding the 2009 disappearance of Sergeant Bowe Bergdahl and his subsequent half decade as a Taliban captive. No decision has been made about his future, military officials said today.

Following his return to the U.S. last year the Army began investigating whether his case requires disciplinary action. At issue is whether the sergeant willfully left his eastern Afghanistan outpost.

Major General Kenneth Dahl conducted the months-long investigation, which concluded in October and was forwarded to the Pentagon. The investigation and its recommendations were forwarded to Milley in December. He heads the U.S. Army Forces Command, and is responsible for reviewing the matter.

The general will decide if Bergdahl should face disciplinary action, which could take the form of a court martial or non-judicial punishment. He may also decide the case warrants no punishment. The Army denied media reports that the decision had already been made.

“To be clear, there have been no actions or decisions on the Sergeant Bergdahl investigation,” said Major General Ronald Lewis, head of Army public affairs. “[General Milley] will determine appropriate action — which ranges from no further action to convening a court-martial.”

“There is no timeline to make that decision and General Milley is not being put under pressure to make a decision either way,” Rear Admiral John Kirby added at a Pentagon briefing.

Bergdahl remains on active-duty at Fort Sam Houston in San Antonio, Texas, until the case is resolved
