A pre-trial hearing in January in the case of Manning, concluded that his defence would be restricted to arguing motive during his trial, scheduled for June 3.

Manning has been accused of leaking thousands of classified documents to WikiLeaks, which revealed a wide range of US war crimes, as well as evidence of corruption and lying by a range of governments.

BradleyManning.org said Manning is “accused of releasing the Collateral Murder video, that shows the killing of unarmed civilians and two Reuters journalists, by a US Apache helicopter crew in Iraq. He is also accused of sharing the Afghan War Diary, the Iraq War Logs, and a series of embarrassing US diplomatic cables.
