The personal flag of the President of the United States is called the Presidential Flag. This flag features the Great Seal of the United States in the center, surrounded by a blue field and gold fringe. The design signifies the authority of the President and is used during official functions and events, representing the officeholder rather than the person themselves. The flag is typically displayed at the White House, in official residences, and at formal presidential events. It serves as a symbol of the presidential office and the responsibilities that come with it.
