The Constitution grants to Congress the power to declare war. However, the President has some limited powers to call the military into action. Biden's position in his previous statement was that even those limited powers granted to the President by the Constitution are subject to the permission of Congress - in essence creating 535 mini-commanders-in-chief over the actual CIC.
Sorry but I strenuously disagree. The President has limited authority to act in an emergency without Congressional approval. The actions we saw last week are well outside those bounds. There is absolutely NO constitutional or legal authority for obama’s actions regarding the farce being carried out over Libya right now.
