In view of the back and forth on the Guantanamo detainees and the legal status of same, an interesting audio document is Sen. Sam Ervin’s (D-NC, right) monlogue–and back and forth with Watergate witness John Erlichmann and his counsel–during the Watergate hearings.
The monologue is about 30 minutes into the audio clip. The date was 26 July 1973.
