Who is Bradley Manning?

As Pfc. Bradley Manning's sentencing phase began Wednesday morning, the convicted leaker has already tallied 1,274 days behind bars.

The question now is how many more of the potential 136 years he'll serve.

The military will give Manning credit for each of his 1,162 days of pre-trial confinement, plus the judge, Col. Denise Lind, credited Manning with an additional 112 days for the harsh treatment he suffered while being held at a Marine Corps Base Quantico brig.
