U.S. Army Sgt. Bowe Bergdahl will be charged with desertion for disappearing from his base in Afghanistan in 2009, NBC News reported on Tuesday.

Bergdahl, who was released from captivity last year in a controversial Taliban prisoner swap, could be charged within a week, the television network said, quoting senior defense officials who were not identified by name.

However, senior Army and defense officials contacted by Reuters could not confirm the report.
