Hoover eventually got control over LBJ over the civil rights and anti-war movements. LBJ was convinced the commies were behind both, and had Hoover spy on them. Of course that was how Hoover worked. Once he got someone in bed with him engaging in some illegal act, he had them.
The only one who really held this off was Nixon. He set up his own group to do such things so he would not be in debt to Hoover (the ‘Plumbers” as they were called.) It really PO’d Hoover, and most people feel it was him that ratted out the Plumbers at the Watergate Hotel.
Hoover died in May 1972. How was he involved in the Nixon reelection campaign?
Most people? Hoover was dead by the time of the first Watergate Hotel’s ‘break in’ by Nixon’s guys. How could he have ratted them out if he was dead?
