WikiLeaks is an international nonprofit organization that publishes otherwise classified or unavailable documents online for public use. Since its launch in 2006, the group claims to have published millions of documents, many relating to the U.S. led wars in Iraq and Afghanistan, but also relating to economic crises and American diplomatic cables. Many of its documents have been published and analyzed by leading news outlets, including the U.K.'s Guardian, the New York Times and New York Daily News. WikiLeaks also runs a lively Twitter account and Facebook page. Founder Julian Assange was arrested in 2010 in connection with a sex crimes investigation.
