I think it goes even deeper than that.
Fair Play for Cuba was the group Lee Harvey Oswald was associated with
Also associated were members of the Finders cult, which was run by a guy named Marion Pettie
Marion Pettie was very good friends with another guy named Charles Marsh. Marsh had his fingers in a lot of shady shit.
After the Kennedy assassination, LBJ's first stop after he got off the plane was Marsh's house.
Marsh was also involved with Sid Richardson, another Texas oil man
Guess who took control of Sid's estate after he died?
Governor Connolly.
Talk about a fucking rabbit hole, this is the biggest one I found so far aside from pizzagate.
