Amazingly, a United States Senator readily admits an acting president doesn't have the constitutional authority to perform a "shakedown" of BP, but sees absolutely nothing wrong with it. This is the typical liberal/progressive mantra: to hell with the constitution; it's for the "greater good."
And as a man who became a household name for accepting the infamous "Cornhusker Kickback" in exchange for his pro-ObamaCare vote, I don't think Ben Nelson is qualified to speak on the subject of "moral authority." For anything.
