Manning, who turns 24 Saturday, has been accused of aiding the enemy, violating the Espionage Act and several lesser charges — enough to send him away for life. Aiding the enemy carries a potential death sentence, but Army officials have said they will not seek it. At the Article 32 hearing, which is likely to last for several days, an investigating officer will determine whether the prosecution has enough evidence to send Manning to trial. It will be up to a convening authority whether to refer the case to a court-martial.
