Army Pfc. Bradley Manning is escorted, in handcuffs, out of a courthouse in Fort Meade, Md., Sunday, Dec. 18, 2011, from a military hearing that will determine if he should face court-martial for his alleged role in the WikiLeaks classified leaks case. Manning is suspected of being the source in one of the largest unauthorized disclosures of classified information in U.S. history.

FORT MEADE, Md. — Military prosecutors at Fort Meade are more than halfway through their witness list at a hearing to determine whether an Army intelligence analyst charged with giving a boatload of classified information to WikiLeaks will be court-martialed.

The Article 32 hearing for Pfc. Bradley Manning enters its fourth day Monday. The government has called 13 witnesses, with up to eight more expected, before the defense begins presenting its case.

Monday's testimony will focus on a forensic examination of Manning's two workplace computers. In the most potentially damaging evidence so far, an investigator testified Sunday that he found more than 10,000 downloaded diplomatic cables and other sensitive information on a computer Manning used.

He says the other computer was used to conduct scores of online searches for WikiLeaks and its founder, Julian Assange. The witness says that seemed odd, since Manning was supposed to be analyzing intelligence about Iraqi terrorist threats.
