There was an 18 1/2 minute accidentally erased section of the tape which everyone was convinced was the smoking gun. Rosemary Woods, Nixon's secretary, said that she accidentally erased it.
So, in the court of public opinion, Nixon was convicted on the evidence contained in a blank tape.
Marjorie woods owned up to about 7 minutes of this as I recall.
Who did the investigations on this?
Who were the tapes turned over to?
Hillary?
