A summary of the link:
1. The president does not sign any commitment to properly treat classified documents unlike all other cleared individuals.
2. Actually, the president has no formal clearance, gets no background investigation, etc. When the people elect him, he becomes the super cleared person.
3. The president can decide at any moment what is classified and what is declassified.
4. The only action for a president violating his duty is impeachment, not criminal prosecution.
5. There is no penalty associated with not following the Presidential Papers Act. Hence, no basis for prosecution.
