U.S. court martial prosecutors called their last witness Tuesday against the army private charged with espionage and aiding the enemy by leaking classified documents to the anti-secrecy website WikiLeaks.
Defendant Bradley Manning is facing 21 charges in connection with the case. He could face life in prison without parole if convicted.
The defense will begin presenting its case on Monday.
Prosecutors have presented evidence in the past four weeks that the former intelligence analyst used military computers in Iraq in 2010 to download hundreds of thousands of documents and battlefield video from a classified network.
Their evidence also supported claims that the late al-Qaida leader Osama bin Laden saw some of the material published by WikiLeaks.
Manning has admitted giving WikiLeaks the trove of diplomatic cables and combat reports from the U.S.-led wars in Iraq and Afghanistan, saying he wanted to spark public debate on U.S. foreign policy.
But he has denied aiding the enemy -- the charge punishable by life in prison.
