The Army Private at the center of the largest information leak in US history could be sentenced in the next few days.
Private First Class Bradley Manning was found guilty on 20 of the 22 counts against him.
He's facing up to 90 years in prison.
A military judge is hearing closing arguments today.
The judge called Manning's conduct "heedless" and "reckless."
Manning's attorneys presented witnesses who said he was under great stress, due largely to his gender identity confusion.
In an unsworn statement last week, Manning told the court that he was sorry.
