Daniel Ellsberg, who leaked the Pentagon Papers that detailed U.S. actions during the Vietnam war, died Friday at this home in Kensington, Calif. He was 92. The cause, his family said in a statement, was pancreatic cancer.

In March, Ellsberg posted on his Facebook page that doctors diagnosed him with inoperable pancreatic cancer on Feb. 17 following a CT scan and MRI.
