A more thorough explanation:

A constitutional officer is a government official whose office is created by a constitution, rather than by a statute. They are authorized by the government to exercise a specific function and their term of office is fixed and defined by the constitution.

Examples of constitutional officers include:

• The President of the United States
• The Governor of a state
• The Mayor of a city

These officials are elected or appointed to their positions and have specific duties and responsibilities outlined in the constitution. They are accountable to the people they serve and must uphold the laws and regulations of their respective governments.

For example, the President of the United States is a constitutional officer who is responsible for executing the laws of the country, serving as commander-in-chief of the armed forces, and representing the United States in international affairs. The Governor of a state is responsible for overseeing the state government, signing or vetoing legislation, and serving as commander-in-chief of the state's National Guard.
