I simply believe The President has a right to designate agents to act on his authority because, and this is obvious, he can't do everything himself face to face with the respective agencies.

Of course. The question isn't whether he can do that - it's whether he did do that with these specific people. The President can give permission to anyone to access anything (subject to law and statute, of course), but that doesn't mean that every single person in the Executive Office of the President has permission to look at every single thing in the federal government.
