Pentagon Papers leaker Daniel Ellsberg dies at 92.

Daniel Ellsberg, the anti-war activist who leaked the Pentagon Papers, revealing secret details of U.S. strategy in the Vietnam War, has died at the age of 92 from pancreatic cancer. Ellsberg 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. He was especially valued, he would later note, for his "talent for discretion."
