Look at the White House transcripts of the most recent press conference:

Q: Can you understand, though, why some people might not trust what you’re saying right now about wanting to —

THE PRESIDENT: No, I can’t.

This is wrong on so many levels:

• The constitution was explicitly created to make sure that we did not have to trust the authorities.  It was intended to create contention, and quite honestly distrust, to make sure that powers are limited.
• He does not understand how people might be concerned that he might not be completely forthcoming.

I am not sure what is more alarming, his complete lack of understanding of the critical in the Constitution concept of the separation of powers, or the pervasive narcissism.

I would be hard pressed to find a better illustration of why the founding fathers were concerned about the possibility of excesses by the executive.
