There have been some recent allegations/speculation that the Israelis were involved. This is because JFK was against the idea of Israel getting nuclear weapons.
This being the reason WHY Trump did not release the JFK files the first time he was POTUS.
It has also been stated recently that is was Pompano who talked Trump out of releasing them.
“It has also been stated recently that is was Pompano who talked Trump out of releasing them.”
I believe that both Trump and Pompeo said so.
