Try reading it again. I said cleared to receive it. Not to disseminate it to those without a security clearance.
The President is cleared to receive any classified data for the obvious reason that he's the boss of those who put on the classified secret tag.
Since there is a mountain of classified data in government, no president can possibly read through, and his underlings have intentionally withheld classified data from him for numerous reasons, any of which could be that they believe that the president would not keep it secret, they can and do keep the president off the need to know list.
My point... is that the President or his VP can downgrade any classified information if they believe that the info does not warrant secret status, And that means they can 'disseminate it to those without security clearance.'
