How many US President's knew the truth behind the JFK assassination and refused to disclose it and why?

George Bush Sr was director of CIA and President.

Gerald Ford was on the Warren Commission and later, unexpectedly became US President

Ford ordered the House Select Commitee on Assassinations

BTW Ford was an Eagle Scout

Obama and Clinton and Bush Jr had to have known

Now that Trump has ordered a full release I am skeptical of disinformation designed to groom the American public with alternate conclusions

They groomed LHO

Why not groom us in 2025 prior to a full release?

Not interested in BS theories Just the truth
