Roger Stones publicity mail-out has this (from Amazon) via Robert Morrow (”expert”)
“By late November, 1963, the Kennedys were within days of politically executing and personally destroying Lyndon Johnson via a two track program: 1) a devastating RFK-fed LIFE Magazine expose of LBJ’s astounding corruption and 2) an RFK-nurtured Senate Rules Committee investigation into LBJ’s habit of taking large bribes and kickbacks.”
I have no idea if this is so, at least the Time Life part should be something that could be corraborated.
There were a lot of unexplained deaths in the decade after the assassination and people close to the scene clammed up. We are now in the time period where would-be witnesses are no longer afraid and may want to tell what they know.
My prediction is there are more shocking revelations to come.
