Oaths in the presidency are commonly done by the elected president and vice president as a form of commitment to their state and duties.

The oath in the United States was first made by the president George Washington on April 30, 1789. Since that moment, every elected U.S. president must say the same oath at the inauguration ceremony.

The presidential oath is written in Article II, Section 1 of the Constitution of the United States. The oath reads:

"I do solemnly swear (or affirm) that I will faithfully execute the office of the President of the United States, and will to the best of my abilities, preserve, protect and defend the Constitution of the United States."

This oath is generally administered by the Chief Justice of the United States. However, it is an agreement among legal experts, and there are no constitutional rules related to this matter.
