Oath of office of the president of the United States

The oath of office of the President of the United States is an oath or promise given by the Chief Justice of the United States to the President of the United States.

It must be done because it is order by the United States Constitution. The oath is given before the President begins his term of office. This is what they say:

“I (name of president) 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.”
