Who is in charge of the executive branch?

The executive branch is headed by the President, who plays a crucial role in governing the country and implementing laws. The President serves as the Commander in Chief of the armed forces, oversees the federal administration, and ensures that laws passed by Congress are enforced. This position represents the highest authority in the executive branch and is essential for maintaining the balance of power within the federal government.

The Prime Minister is a term associated with parliamentary systems, which is not applicable in the United States. The Speaker of the House is a leader within the legislative branch and is responsible for overseeing the House of Representatives, not the executive branch. The Chief Justice leads the judicial branch, focusing on the interpretation of laws rather than their execution. Therefore, the President's role as the head of the executive branch makes this answer the most accurate.
