What Obama said as a presidential candidate in 2007

During his first campaign for president in 2007 Barack Obama answered in writing some questions from writer Charlie Savage of Boston.com.

1. Does the president have inherent powers under the Constitution to conduct surveillance for national security purposes without judicial warrants, regardless of federal statutes?

The Supreme Court has never held that the president has such powers. As president, I will follow existing law, and when it comes to U.S. citizens and residents, I will only authorize surveillance for national security purposes consistent with FISA and other federal statutes.

2. In what circumstances, if any, would the president have constitutional authority to bomb Iran without seeking a use-of-force authorization from Congress? (Specifically, what about the strategic bombing of suspected nuclear sites -- a situation that does not involve stopping an IMMINENT threat?)

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.
