In my reading, logtroll is right, Congressional Oversight of the President, is not directly mentioned or granted in the Constitution. However, it is implied. Here is the Supreme Court Decision that firmly established that Congress has the power of oversight: Watkins v. United States, 354 U.S. 178 (1957) and a Constitution Society article on the matter: Oversight Is a Constitutional Necessity, Not a Luxury.

I am no lawyer, so I may be so far out in left field on my reading that being wrong would be a mercy.

Life is like a PB&J sandwich. The older you get, the moldery and crustier you get.

Now, get off my grass!
