During this week's debate, President Obama stated he is taking full responsibility for the attack by terrorists on the U.S. embassy in Libya that led to the death of the ambassador and three other Americans. Whether or not he or Joe Biden knew about the request for extra security, they should have known. (I believe they did know.) But if they didn't know, why not? The cover-up afterward is undeniable. Someone should be held accountable and lose their job, and since the president assumed full responsibility, he should fire himself immediately.
