Does anybody really think that Nixon would have been the only President to have talked about such things, instead of the only one to have made recordings?
Not working, Obama.
You can’t use Nixon.
Try something else.
Nixon wasn’t the only one to have made recordings. KENNEDY installed the system (and he taped MLK’s phone calls).
LBJ had tapes that documented corruption within his reign (he permitted a bank merger in Texas in exchange for a signed letter from the Houston Chronicle that they would not print stories in opposition to his policies).
Those tapes were not released for DECADES after the Nixon tapes. Some of the Kennedy tapes are still suppressed if I recall (or “are unplayable now”).
