I could probably write you a history of Watergate, but all the sauce is gone.
Here's a short timeline:
Agnew forced out by…Nelson Rockefeller and frens leaves
VP vacancy to be filled
Rockefeller's people go to Nixon to have Nelson appointed VP
Nixon sees what they did to Agnew, knows they're coming for him next and gives them the big middle finger, Gerald Ford.
Gerald Ford appoints Rockefeller as his VP.
Rockefeller, after his stint as VP, eventually dies in the arms of a hooker in Manhattan.
Nixon spared the country by telling Rockefeller to fuck off and resigning, but he gets no credit for that.
