Julian Assange and WikiLeaks

Julian Assange (b. 1971) is the founder of WikiLeaks, an organization that has leaked information to the public since December 2016. Known as a "group of hackers", WikiLeaks and Julian Assange have become notorious for whistle-blowing.

Famous WikiLeaks Leaks
More recently, on March 27, 2018, according to The Washington Post, Assange was denied internet access by the Ecuadorian Embassy for violating a signed agreement to not interfere with "the affairs of other states".
 * The "War Logs": The release of thousands of internal U.S. Defense Department documents about the wars in Iraq and Afghanistan.
 * Sarah Palin's Email: I was reported that Sarah Pain was using Yahoo!'s email service (her personal email address) for work-related matters.
 * Climate Research: "The documents apparently showed that information which didn't fit with current climate change theories (that it is bad) was suppressed."
 * 2016 U.S. Presidential Elections (Clinton's Emails): "On March 16, 2016 Wikileaks published a searchable archive containing the contents of more than 30,000 emails (and attachments) that were sent to and from Secretary Clinton on her private server." It is argued that it was not necessarily the contents of the emails that contributed to Clinton losing but the 'air of suspicion' due to "the pace, frequency, and size" of the leak (or hack). According to CNN, in 2016, Alexander Nix, chief executive of Cambridge Analytica, contacted Julian Assange for access to Clinton's emails. He apparently wished for the contents to be created into "a searchable database for the campaign or a pro-Trump political action committee".
