Daniel Ellsberg, the Pentagon Papers leaker, dies at 92.

Daniel Ellsberg, the most important whistleblower of our times, has died at the age of 92. His 1971 leaking of what became known as the Pentagon Papers showed that virtually everything the American public had been told by its leaders about the Vietnam war was false. His leaks resulted in a landmark decision in favour of freedom of the press and led to the downfall of US President Richard Nixon. Ellsberg spent the rest of his life as a peace activist, encouraging others to reveal government malfeasance and supporting those who did.
