Washington: In a case with significant First Amendment implications, the US filed new charges Thursday against WikiLeaks founder Julian Assange, accusing him of violating the Espionage Act by publishing secret documents containing the names of confidential military and diplomatic sources. The Justice Department’s 18-count superseding indictment alleges that Assange directed former Army intelligence analyst Chelsea Manning in one of the largest compromises of classified information in US history.

The case comes amid a Justice Department crackdown on national security leaks and raised immediate fear among news media advocates that Assange’s actions including soliciting and publishing classified information are indistinguishable from what traditional journalists do on a daily basis.

Assange’s lawyer, Barry Pollack, said Thursday that the “unprecedented charges” against his client imperil “all journalists in their endeavour to inform the public about actions that have been taken by the US government.” The Reporters Committee for Freedom of the Press called the case a “dire threat” to media freedom, and the American Civil Liberties Union said it was the first time in history a publisher was charged for disclosing truthful information. But Justice Department officials sought to make clear that they believed Assange’s actions weren’t protected under the law, though they declined to discuss the policy discussions that led to the indictment. The new Espionage Act charges go far beyond an initial indictment against Assange made public last month that accused him simply of conspiring with Manning to crack a Defense Department computer password. “Julian Assange is no journalist,” said Assistant Attorney General John Demers, the Justice Department’s top national security official. “No responsible actor, journalist or otherwise, would purposely publish the names of individuals he or she knew to be confidential human sources in war zones, exposing them to the gravest of dangers.” Zachary Terwilliger, the US Attorney in Alexandria, Virginia, where the case was brought, said Assange was charged with illegally soliciting classified information and not simply publishing it. He said that while the indictment alleges that he published hundreds of thousands of documents, it charges him with disclosing only a “narrow set of documents” related to the identities of confidential sources. Prosecutors sought throughout the document to make a distinction between what Assange did as the founder and “public face” of WikiLeaks and the work of journalists. They noted, for example, that he promoted his site to a convention of European hackers and published a list of the classified information he sought as “The Most Wanted Leaks of 2009.” They described how Assange worked with Manning to improperly access Defense Department computers to gain access to thousands of pages of material and encouraged her as she delved through databases for information. Prosecutors also say the danger wasn’t just to the US government, but to people who worked with it. Reports from the wars in Afghanistan and Iraq published by Assange included the names of Afghans and Iraqis who provided information to American and coalition forces, while the diplomatic cables he released exposed journalists, religious leaders, human rights advocates and dissidents in repressive countries. Assange said in an August 2010 interview that it was “regrettable” that sources disclosed by WikiLeaks could be harmed, the indictment says. Later, after a State Department legal adviser informed him of the risk to “countless innocent individuals” compromised by the leaks, Assange said he would work with mainstream news organisations to redact the names of individuals. WikiLeaks did hide some names but then published 250,000 cables a year later without hiding the identities of people named in the papers. Justice Department officials mulled charges for Assange following the documents’ 2010 publication, but were unsure a case would hold up in court and were concerned it could be hard to justify prosecuting him for acts similar to those of a conventional journalist. The posture changed in the Trump administration, with former Attorney General Jeff Sessions in 2017 calling Assange’s arrest a priority. Attorney General William Barr paused for several seconds at his confirmation hearing when asked if his Justice Department would ever jail journalists, finally saying there were scenarios when he could envision it as a last resort.
