You are describing a symptom, not the root cause.
The root cause is everyone in government is hiding shit, Trump included. (I'm not talking about sub launch codes, and stuff like that).
People are getting tired of it. All of it, whether for good reasons or bad. There are more normies on this board now, and more to come. You are going to see more of it.
Then again, I'm from the school of "kill them all, and God will sort out the good ones."
Now, on the particular item of declas I can see why Trump is slow rolling that. One of the few times I I agree with him. Perfect time to exhibit how corrupt government officials behave. Gotta show the normies over and over.
