Very much so.
If there is anything that is going to keep "disclosure" from happening, it is this.
Someone once told me that disclosure won't happen unless every former President is dead and a new one has yet to be sworn in. I thought he was kidding at the time. Now, not so much.
I used to think some Presidents were not read into the program at all. Now, I'm pretty sure all Presidents have some knowledge of the program...how much and how deep depends on their background. George Bush Senior was former CIA so he knew it all and I can assume his son was well informed. Carter, being a Navy man, probably knew more than Clinton or Obama. Trump was likely told little.
“Trump was likely told little.”
Interesting topic.
Many researchers believe President Trump is “playing dumb” on this topic.
His uncle is a fascinating individual—most likely shared some of the “secrets”:

Now the next clue needs you to fasten your seat belt—this book actually exists:

There are two other similar books written in the 1890s by the same author.
This is a wild rabbit hole...
