Wikileaks is an international non-profit organization that publishes secret information from anonymous sources to expose illegal or unethical activities. It is led by Julian Assange, an Australian computer programmer who seeks to open governments and has gained notoriety for leaks like the Collateral Murder video showing a US air strike in Baghdad. Some of Wikileaks' most high-profile releases include documents exposing illegal activities at a Swiss bank, the US military's footage of an air strike in Baghdad that killed civilians, secret files about prisoners at Guantanamo Bay detailing torture, and emails from Hillary Clinton's presidential campaign.
