Example: Samantha Power served as the U.S. Ambassador to the United Nations from 2013 to 2017 after Senate confirmation.
Common misconception: An ambassador can make foreign policy independently of the U.S. government. Ambassadors represent U.S. policy and operate under the authority of the President and Secretary of State.
