The oath of office:
I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States.
Yesterday: cnn.com:
At 10:15 p.m., Bush gave his address to the nation. "On my orders, coalition forces have begun striking selected targets of military importance to undermine Saddam Hussein's ability to wage war," he said.
...
At the White House, officials said that just before Bush addressed the nation, he pumped his fist, winked, and said "I feel good." He then delivered his address, which lasted four minutes.
The man enjoy's his work.
