Who heads the executive branch of government?

The head of the executive branch of government is the President, which is why this answer is correct. The executive branch is one of the three branches of government, established by the U.S. Constitution, and its primary function is to enforce and implement laws. The President serves as the Chief Executive Officer of the country and is responsible for overseeing the various federal agencies, directing national policy, and acting as the Commander in Chief of the armed forces.

In contrast, the Speaker of the House, the Supreme Court Chief Justice, and the Senate Majority Leader have different roles within the government structure. The Speaker presides over the House of Representatives, the Chief Justice leads the judicial branch and oversees the Supreme Court, and the Senate Majority Leader is responsible for managing legislative business in the Senate. Each has a significant role, but none are tasked with leading the executive branch.
