FORT MEADE, Md. -- Lawyers are preparing their arguments on whether an Army private who gave government secrets to WikiLeaks should be acquitted of some charges due to a lack of incriminating evidence.

The judge in the case of Pfc. Bradley Manning says she'll hear defense and government arguments Monday afternoon on whether to acquit the soldier of the most serious charge -- aiding the enemy -- and six lesser charges.

Manning's court-martial is drawing to a close at an Army base outside Baltimore. The defense rested its case last week.

Manning has acknowledged leaking hundreds of thousands of military and State Department documents to the anti-secrecy website to expose what he considered wrongdoing. The government has sought to prove his actions harmed national security.
