Buzhardt reviews the tape from June 23 and hears the President and Haldeman decide to tell the FBI to back off on Watergate. The tape undercuts the President’s assertion that he was unaware of the coverup until the Dean conversation the following March. There is also no mention of anything related to national security which Nixon had also been using as an excuse to avoid releasing certain tapes. Buzhardt believes the tape is the fatal blow to Nixon’s presidency.
