The U.S. Army and an attorney for Sgt. Bowe Bergdahl say military investigators have begun questioning the solider about his disappearance in Afghanistan that led to five years in captivity by the Taliban.
Eugene R. Fidell says his client is cooperating with the investigation at Fort Sam Houston in San Antonio on Wednesday.
Fidell declined to comment on what Bergdahl is being asked.
An Army spokeswoman says Bergdahl was advised of his rights.
The investigation's findings will help determine whether the 28-year-old is prosecuted for desertion or faces any other disciplinary action.
Bergdahl had been receiving care at Fort Sam Houston since returning to the United States on June 13 after his release by the Taliban on May 31.
Earlier this month, the Army announced Bergdahl was given a desk job.
