All of my power comes from the Constitution and so does my purpose:
Hello, I am the President of the United States.
As President I have many titles and duties including: Chief Executive, Head of State, Commander-In-Chief, Agenda Setter, Keeper of the Economy & Party Chief.
"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."
This is my Vice President. He's here to help me out. The Constitution doesn't say much about his duties other than he acts as a tiebreaker should congress come to an impasse while voting.
My unofficial duties include dealing with foreign affairs when the President cannot. I also help advise the President almost as much as the Cabinet does.
Speaking of the Cabinet, here are a few of my trusted advisors.
This is the Secretary of State. He manages our relationships with foreign countries.
This is the Secretary of Treasury. She collects taxes, prints money and deals with the nation's finances.
This is the Secretary of Defense. She manages the armed farces and conducts wars overseas.
Together we make up the Executive Branch of the government.
Along with the rest of the Cabinet members and Executive officers.
The main purpose of the executive branch is to enforce the laws made by our government and most importantly, the Constitution.
This is the Executive Branch and I hope you enjoyed your White House visit.
