Actually the law defines presidential records and personal records.
www.law.cornell.edu
The term “
Presidential records” means
documentary materials, or any reasonably segregable portion thereof, created or received by the President, the President’s immediate staff, or a unit or individual of the Executive Office of the Presidentwhose function is to advise or assist the President, in the course of conducting activities which relate to or have an effect upon the carrying out of the constitutional, statutory, or other official or ceremonial duties of the President.
The term “
personal records” means all
documentary materials, or any reasonably segregable portion therof,
[2] of a purely private or nonpublic character which do not relate to or have an effect upon the carrying out of the constitutional, statutory, or other official or ceremonial duties of the President.
Now, do you think an invasion plan prepared by the DoD would be a presidential record or a personal record under these definitions?
