These are good examples of congressional power as defined in the Constitution. In each case the legislative branch created new agencies and delegated some power to the executive branch. But not the reverse.

Can you give any example of the opposite? A case where the executive has delegated power to the legislative or judicial branches?

The fact that these "independent" bodies even exist outside executive control in the first place. The fact that a President signed the legislation that created these bodies is an example of passing executive power to the legislative.

Signing (or refusing to sign) legislation is a good example of the President exercising executive power. I'm not aware of any occasion when the President delegated that power to Congress (or to the Supreme Court). Can you cite something?

Maybe we have a misunderstanding. I'm not asking a kind of broad speculative question like "hypothetically, what could a hardcore monarchist say to critique our constitutional system?"

I was asking for a plain old real-world example of delegation of power from the executive branch to another branch. In the real history of the USA. Agreed on one point, though: I can't think of one either.
