Pentagon Papers whistleblower Daniel Ellsberg passes away at 92.

Daniel Ellsberg, the whistleblower who leaked the Pentagon Papers, revealing the US government's doubts and deceit about the Vietnam War, has died at the age of 92. Ellsberg's actions led to a landmark First Amendment ruling by the Supreme Court and inspired acts of retaliation by President Richard Nixon that helped lead to his resignation. The Pentagon Papers were first published in The New York Times in June 1971, documenting that the US had defied a 1954 settlement barring a foreign military presence in Vietnam, questioned whether South Vietnam had a viable government, secretly expanded the war to neighboring countries, and had plotted to send American soldiers even as Johnson vowed he wouldn’t.
