Daphne O'Connor was an American FBI counter-intelligence agent. In preparation for the 1968 Democratic National Convention protests, she was assigned to go undercover as a member of the counterculture movement and infiltrate the protests by getting close to Jerry Rubin. She went on to testify at the trial of the Chicago Seven, where she testified that Rubin, Abbie Hoffman, David Dellinger, and Rennie Davis had led 800 protesters to police headquarters to demand the release of Tom Hayden.
