Private First Class Manning, has been accused of releasing the Collateral Murder video that shows the killing of unarmed civilians and two Reuters journalists by an American helicopter crew in Iraq, as well as hundreds of thousands of diplomatic cables and classified documents.
Manning has since been detained without trial, which included his infamously harsh treatment in Quantico solitary confinement, referred to by his defense as "unlawful pretrial punishment."
Bradley Manning faces 22 charges, including that of "aiding the enemy," which means he may be jailed for life with no chance of parole, if convicted.
The pretrial hearing for Manning's case is scheduled for February 26 -- March 1. During the hearing, the judge will rule on the defense’s motion to dismiss charges for "unconstitutional" lack of a speedy trial.
According to US law, the trial should have taken place within 120 days of Manning's detention.
The Bradley Manning Support Network has said that current protests and teach-ins are merely a preparation for a larger action during the court martial trial, which is scheduled to start June 3, 2013
