Julian Assange faces up to five years in prison for his role in “one of the largest compromises of classified information in the history of the United States,” federal officials said today in unsealing a March 2018 indictment against the WikiLeaks founder.

Assange, 47, was arrested Thursday in the United Kingdom after Ecuador revoked the asylum he had enjoyed in its London embassy since 2012. British authorities detained him for jumping bond in a sexual assault case, but that charge was immediately eclipsed by a U.S. request to extradite him to face a conspiracy charge in the incident that made Assange notorious: the 2010 release of hundreds of thousands of U.S. military documents and State Department diplomatic cables related to the wars in Afghanistan and Iraq.
