Congress' responsibilities are still on Sen. Chuck Grassley's mind even though the legislature is not in session today.
The Iowa Republican took to his famous Twitter account to sum up his thoughts on Congress' oversight powers in a pun:
:)my rule for doing Constitution rule of ovrsite: In God we trust. Everthing else we oversight. :)
Or as the Founders put it in the "necessary and proper" clause:
To make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof.
