Daniel Ellsberg, who leaked the voluminous, top-secret history of the Vietnam War known as the Pentagon Papers, a disclosure that led to a landmark Supreme Court ruling on press freedoms and enraged the Nixon administration — serving as the catalyst for a series of White House-directed burglaries and “dirty tricks” that snowballed into the Watergate scandal — died June 16 at his home in Kensington, Calif. He was 92.
