The Supremacy of the Vice President

From USNews:

An important legal ruling is pending over Vice President Cheney's refusal to disclose statistics on document classification and declassification activity. The Information Security Oversight Office, which is responsible for the policy and oversight of the government's security classification system, has asked Attorney General Alberto Gonzales to direct Cheney's office to disclose these statistics.

If I understand this kertuffle correctly, there is an executive order that all classified documents must be tracked statistically. There is also an executive order that the Vice President can classify and declassify documents. Cheney is saying his executive power to classify is freed from the executive order to keep statistics by right of his legislative powers.
How can Feckless Leader permit this infringement of his God given executive powers by the legislative powers? Who's on first? Where will it all end?

This is a hint here that Cheney believes himself beyond executive orders by his constitutional legislative powers as Vice President. He believes he can follow or not follow them as he see fit. Very interesting. Could Bush even revoke his powers to classify, or is it too late?

What other powers does he have?
