I’m not really into this stuff I got over it a long time ago, but I have a friend who really is and he bombards me with UFO stuff.
Anyway I don’t think they would or do brief the president over this stuff no matter who it is, and if they do the president realizes what a disaster it would be for whatever reasons to release it publicly so they don’t. I’ve heard it said that Jimmy Carter was one of the few who asked and was briefed on the subject, and he had an extreme reaction and was seen later crying/contemplating at his desk afterward, perhaps because of his religious beliefs.
Anyway who knows
Ford and Billy Jeff also requested to be briefed. Apparently Billy Jeff got stonewalled on Majestic 12 information.
