"The Oath." It sounds like the name of a book, and indeed, there have been many volumes with that name. But none more relevant this week than The Oath specified in the Constitution for the president of the United States when he takes office.
The 35 words in Article II, Section I, of the Constitution read as follows:
"I do solemnly swear 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."
