Who is Pfc. Bradley Manning?

- Pfc. Bradley Manning, 22, a dual U.S. and British citizen, is being held in pre-trial confinement at a maximum security brig in Quantico, VA. Authorities arrested him in May, just 2 months after WikiLeaks released the "Collateral Murder" video. Those images showed U.S. forces in a helicopter kill two Iraqi journalists among others. The U.S. Military defended its actions, saying the shootings were warranted.

- According to sources familiar with the ongoing investigation, Manning was exposed after telling notorious online hacker, Adrian Lamo, he was the one who released the video. Lamo shared this knowledge with authorities, later saying Manning also took credit for for releasing hundreds of thousands of sensitive diplomatic cables.

- Pfc. Manning was charged on July 5 with four specifications under Article 92 of the Uniform Code of Military Justice for violating Army Regulation 25-2 (Information Assurance Policy), and eight specifications under Article 134 for violating federal statutes related to the receipt of classified information (18 U.S.C. 793) and wrongful access of a government computer (18 U.S.C. 1030).

-He could face more charges before the investigation is over. Sources say the investigation could wrap in the next few weeks. A trial, however, could be more than a year away. Army officials say Manning's mental health evaluation is not set to be complete until around February of 2011. Only then can a trial date be set.

- Pfc. Manning is gay and there is some speculation the military's policy banning openly serving gays served as his motivation for leaking classified documents. Prior to his arrest he posted Facebook messages saying "military intelligence" is an oxymoron. He also posted that he was "beyond frustrated."

- What possible penalties does Manning face if he is found guilty?   As the charges currently stand the maximum punishment Pfc. Manning could face would be 52 years confinement, forfeiture of all pay and allowances, and a dishonorable discharge. The investigation remains open and the charges represent an accusation only; Pfc. Manning is presumed innocent until and unless proven guilty.
