THEN: Remarks in an interview with the Boston Globe in Dec 2007
"The President does not have power under the Constitution to unilaterally authorize a military attack in a situation that does not involve stopping an actual or imminent threat to the nation. As Commander-in-Chief, the President does have a duty to protect and defend the United States. In instances of self-defense, the President would be within his constitutional authority to act before advising Congress or seeking its consent. History has shown us time and again, however, that military action is most successful when it is authorized and supported by the Legislative branch. It is always preferable to have the informed consent of Congress prior to any military action."
NOW: Remarks made in a radio address from Brazil (where he is on vacation ... AGAIN!)
"Today I authorized the armed forces of the United States to begin a limited action in Libya in support of an international effort to protect Libyan civilians."
Well, as I have pointed out a number of times, what this jackass says means NOTHING. You must watch to see what he DOES.
