Who heads the executive branch of the United States government?

The head of the executive branch of the United States government is the President of the United States. This role encompasses the administration of federal laws, conducting foreign policy, and serving as the Commander-in-Chief of the armed forces. The President is responsible for ensuring that laws are faithfully executed and has the authority to appoint Cabinet members, who advise on various aspects of governance.

In contrast, the Chief Justice heads the judicial branch and is responsible for overseeing the Supreme Court. The Prime Minister, while a key leader in other countries such as Canada or the United Kingdom, does not apply in the U.S. context, as the United States does not have a parliamentary system. The Senate Majority Leader is a significant position within the legislative branch, but does not play a role in the executive functions of government. Thus, the delineation of powers within the U.S. government structure clearly identifies the President as the leader of the executive branch.
