Note that the declassification process for documents re: national security have to go through the originator in National Intelligence before it can be declassified by POTUS.
They have the right to challenge it. It is clear that TFG did none of those things.
The legal basis for the classification system comes from the president’s constitutional authority as commander in chief. Presidents have established and developed it through a series of executive orders dating to the era encompassing World War II and the early Cold War. The current directive,
Executive Order 13526, was issued by President Barack Obama in 2009.
Executive Order 13526- Classified National Security Information
PART 3 -- DECLASSIFICATION AND DOWNGRADING
Sec. 3.1. Authority for Declassification. (a) Information shall be declassified as soon as it no longer meets the standards for classification under this order.
(b) Information shall be declassified or downgraded by:
(1) the official who authorized the original classification, if that official is still serving in the same position and has original classification authority;
(2) the originator's current successor in function, if that individual has original classification authority;
(3) a supervisory official of either the originator or his or her successor in function, if the supervisory official has original classification authority; or
(4) officials delegated declassification authority in writing by the agency head or the senior agency official of the originating agency.
(c) The Director of National Intelligence (or, if delegated by the Director of National Intelligence, the Principal Deputy Director of National Intelligence) may, with respect to the Intelligence Community, after consultation with the head of the originating Intelligence Community element or department, declassify, downgrade, or direct the declassification or downgrading of information or intelligence relating to intelligence sources, methods, or activities.

Who has the power to classify and declassify information?
In the normal course of business, certain officials who have been designated as “original classification authorities” in federal departments and agencies can do so. They are considered to be exercising the president’s power over such matters, which has been delegated to them.
Are there formal procedures for declassifying information?
Yes. The 2009 executive order directs the head of the department or agency that originally deemed information classified to oversee declassification reviews, and it sets some standards for them.
The executive branch
has regulations laying out the process that should be followed, such as a requirement to make sure that other agencies and departments with an interest in the secret are consulted. There are also procedures for the removal of classification markings on documents.
