Who is the head of the legislative branch?

The head of the legislative branch is Congress, which is comprised of two houses: the Senate and the House of Representatives. This branch is responsible for making laws, and it plays a crucial role in the federal government by representing the interests of the citizens. Each member of Congress is elected to serve the people and contribute to the law-making process. While the Vice President does have a role in the Senate, primarily as the President of the Senate, it is Congress as a whole that represents the legislative branch. The President, while a significant part of the executive branch, does not head the legislative branch. Similarly, the Supreme Court is part of the judicial branch and does not hold authority over legislative functions. Therefore, Congress is the correct answer as it encompasses all legislative duties and powers within the government.
