There are multiple possibilities
>Trump received disclosure but has been coerced or threatened into silence (doubtful)
>Trump is in on the conspiracy
>Trump is an alien
>Aliens exist but the US government has no concrete knowledge of them
>Aliens haven't contacted Earth
There's also the possibility he hasn't been told. With his mouth a secret like that would be front page news the same day.
ummm
maybe the president isnt really in charge and the country is run by the deep black intelligence agencies.
Bush II, Clinton, and Obama have all stated that the first thing they did in office was ask about the "UFO issue" and they were told that they do not have a "need to know"
We DO NOT live in a democracy.
Clinton had a big thing about it. He was pissed and gave a speech about how he didnt know what was going on. I dont knsow about the other presidents though.
Because he doesn't know they're aliens. He just thinks they're his supporters.
