By definition, when the President authorizes any change in classification, his order trumps any other person, position, or institution. The President cannot "leak" or delegate "leaking" to his subordinates.
EXECUTIVE ORDER 12958: CLASSIFIED NATIONAL SECURITY INFORMATION
Sec. 1.4. Classification Authority. (a) The authority to classify information originally may be exercised only by:
(1) the President;
(2) agency heads and officials designated by the President in the Federal Register; or
(3) United States Government officials delegated this authority pursuant to paragraph (c), below.
A liberal will ask "is declassifying the same as leaking"? It will be argued that if information is leaked, it isn't necessarily declassified.
Bump for reference.
