I held a TS/SCI clearance for almost 30 years, so I understand the subject better than your average Freeper.
Ah, but were you a president that declassified things for thirty years?
I held such a clearance too. You are misunderstanding the difference between authority and officer.
The authority decides what is classified. The officer enforces the rules for the classification.
As President, Trump can do pretty much what he wants. Congressional laws cannot change his authority to declassified. Once declassified, the officer only enforces the rules for unclassified info.
The process to publish declassified info is downstream from the declassification.
You were a classification officer, not an authority.
