Manning, allegedly responsible for releasing documents and videos of US Army and government military and diplomatic activity, has been held in solitary confinement since July 2010. Manning faces a maximum jail sentence charge of 52 years if convicted.

The episode will include an interview with journalist David House -- a close friend of Manning and the only civilian allowed to visit the alleged whistleblower in jail. The episode will also cover internal Wikileaks disputes and the release of dangerous information for public viewing.

The Four Corners episode "The Forgotten Man" will air on ABC1 on February 14 at 8:30pm.
