WikiLeaks founder Julian Assange may be the most vocal proponent of his website, but officials believe the unprecedented release of hundreds of thousands of U.S. military and State Department documents by WikiLeaks would not have been possible without junior U.S. Army military analyst Bradley Manning.
Manning is accused of illegally downloading the enormous cache of documents, which includes diplomatic cables from U.S. embassies the world over, from government computers and sending them to WikiLeaks. In March, the military added another 22 charges including aiding the enemy -- a charge that could potentially carry with it the death penalty. The prosecution, however, told Manning's defense team in March it would not recommend capital punishment.
Kim, a State Department intelligence advisor, was indicted in August 2010 for allegedly disclosing national defense information to a news organization in June 2009 and then allegedly lying to the FBI about it. Kim has pleaded not guilty. The news organization was not named by prosecutors, but a Fox News reporter published a story in June saying that North Korea would respond to threatened U.N. sanctions with a nuclear test. Kim was charged with disclosing top secret information about the military capabilities of another country.
Kim has sought to have the indictment tossed as a violation of due process and his First Amendment right to free speech.
