Bradley Manning presses for dismissal of charges From Larry Shaughnessy and Josh Levs, CNN April 24, 2012 -- Updated 1414 GMT (2214 HKT) Manning returns to court to push for dropping charges His attorneys filed two motions last week He is charged with aiding the enemy and other counts Manning could face life in prison if convicted Fort Meade, Maryland (CNN) -- Pfc. Bradley Manning returns to court Tuesday to push for all charges against him to be dropped. Manning is the Army intelligence analyst suspected of leaking hundreds of thousands of classified military and state department documents while serving in Iraq. Many of those documents ended up on the WikiLeaks website. His attorneys filed two motions last week. One pushes for all charges against Manning to be dismissed. If that fails, the second pushes for some charges to be dropped.. The latter filing argues that the defense should be allowed to review "grand jury materials" that are in the possession of military authorities. Manning's attorneys put redacted versions of the two motions online. The website, from the law offices of David E. Coombs, explains that the government "has opposed the public filing of motions due to concerns over revealing protected information. In response to the government's concerns, the defense has voluntarily redacted its motions in areas where the government opposes public release of the referenced information. Oral arguments over those and other motions from both sides will take place during what's expected to be a three-day hearing. Coombs, a private attorney whose fees have been paid by Manning supporters around the world, has tried previously to get the charges dismissed. Prosecutors have said they've complied with rules governing the mandatory disclosure of non-classified evidence. And they've argued that the court has not explained to them how they can disclose evidence categorized as classified. Manning is facing charges including aiding the enemy, wrongfully causing intelligence to be published on the Internet, transmitting national defense information and theft of public property or records. He could go to prison for life if convicted. Coombs hasn't said whether he'll request a trial by a military judge, a panel of senior officers or a panel that includes one-third enlisted non-commissioned officers.
