Whistleblower Daniel Ellsberg who exposed Vietnam War secrets dies

Daniel Ellsberg, the history-making whistleblower who by leaking the Pentagon papers revealed longtime government deceit about the Vietnam War and inspired acts of retaliation by US President Richard Nixon that helped lead to his resignation, has died. He was 92.

Ellsberg, whose actions led to a landmark First Amendment ruling by the Supreme Court, had disclosed in February that he was terminally ill with pancreatic cancer. His family announced his death Friday morning in a letter released by a spokeswoman, Julia Pacetti.

“He was not in pain, and was surrounded by loving family,” the letter reads in part. “Thank you, everyone, for your outpouring of love, appreciation and well-wishes to Dan in the previous months. It all warmed his heart at the end of his life.”

Until the early 1970s, when he disclosed that he was the source for the stunning media reports on the 47-volume, 7,000-page Defense Department study of the U.S. role in Indochina, Ellsberg was a well-placed member of the government-military elite. He was a Harvard graduate and self-defined “cold warrior” who served as a private and government consultant on Vietnam throughout the 1960s, risked his life on the battlefield, received the highest security clearances and came to be trusted by officials in Democratic and Republican administrations.

The Pentagon Papers were first published in The New York Times in June 1971, with The Washington Post, The Associated Press and more than a dozen others following. They documented that the U.S. 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.
