The Nixon Presidential Library just just released the transcript of Richard Nixon’s grand jury testimony during the Watergate trials, which includes an explanation for the missing 18½ minute recorded conversation between Nixon and his chief of staff.
There are more than two dozen folders and PDF documents from the trial.
In May 1975, the Watergate Special Prosecution Force (WSPF) decided that it was necessary to question former President Richard M. Nixon in connection with various investigations being conducted by the WSPF. Mr. Nixon was questioned over the period of two days, June 23 and June 24, 1975, and the testimony was taken as part of various investigations being conducted by the January 7, 1974, Grand Jury for the District of Columbia (the third Watergate Grand Jury). Chief Judge George Hart signed an order authorizing that the sworn deposition of Mr. Nixon be taken at the Coast Guard Station in San Mateo, California with two members of the grand jury present.
