WikiLeaks soldier to take witness stand in own defense FORT MEADE, Maryland (Reuters) - The U.S. Army intelligence officer accused of slipping military and diplomatic secrets to WikiLeaks is expected to take the witness stand on Thursday, when he will read aloud from a 35-page statement defending himself in the espionage case. Private First Class Bradley Manning was set to enter a formal plea to the 22 charges against him at a pre-trial hearing before a U.S. military judge. In previous hearings, Manning has offered to plead guilty to various lesser charges in violation of the Uniform Code of Military Justice, including the unauthorized possession and willful distribution of information accessed in the Combined Information Data Networks, a military database, for both Iraq and Afghanistan. He has said he will plead not guilty to the most serious charge of aiding the enemy, which is a violation of the federal Espionage Act, among others. Manning, who has been jailed for over 1,000 days, could face life imprisonment if convicted of that top charge. At a pre-trial hearing on Tuesday, military judge Colonel Denise Lind said she would decide on Thursday how much Manning will be able to read aloud from a 35-page statement he has prepared. Manning's lawyers have also filed a motion to request a trial by judge, leading to speculation that Manning might forego a trial by jury for his court martial, set to begin June 3. The Office of the Judge Advocate General said on Wednesday it released 84 judicial orders and rulings in response to a Freedom of Information Act filed by several news agencies. To date, documents totaling 30,000 pages have been filed by the parties or issued by the military judge in the case. Lind has denied a request by the defense to dismiss all charges based on violations of Manning's right to a speedy trial. But under a ruling last month by Lind, Manning would have any eventual sentence reduced by 112 days to compensate for the markedly harsh treatment he received during confinement at Quantico Marine Base. Manning was arrested in Iraq in May 2010 and charged with downloading thousands of intelligence documents, diplomatic cables and combat videos while with the 10th Mountain Division's 2nd Brigade intelligence operation in Iraq and forwarding material to WikiLeaks.
