The President of the United States is in charge of which branch of government?

Why this is the answer

The President is in charge of the executive branch, the part of the government that carries out federal laws. The branch is much bigger than one person: it includes the Vice President, the President's Cabinet and the executive departments and agencies. Congress writes the laws and the courts review them; the executive puts them into effect. Memory hook: "to execute" means to carry out, and the executive branch carries out the laws.
