You may have a point, I’ve never see a “SECRET SCI” cover sheet. What is needed is to stamp “DECLASSIFIED ON JAN 18, 2021 PER PRESIDENTIAL ORDER” in large letters over each document.
Classifcation begins and ends with the POTUS!!! If he says he declassified it it is declassified. No question!!
No it doesn’t have to have that stamped on it. Those papers are for his Library. He deemed them unclassified so they are in fact unclassified! Hitlery did not have this ability!!
