Daniel Ellsberg

Daniel Ellsberg, the U.S. military analyst whose change of heart about the Vietnam War led him to leak the classified “Pentagon Papers,” exposing US government deception about the war and igniting a major freedom-of-the-press battle, died on Friday at the age of 92, according to his family.

Ellsberg, who was diagnosed with incurable pancreatic cancer in February, died at home in Kensington, California, according to his family.
