Who is NOT part of the executive branch?

The Senate is not part of the executive branch because it is a component of the legislative branch of the government. The legislative branch is responsible for making laws and consists of the Senate and the House of Representatives. In contrast, the executive branch is charged with enforcing and implementing laws and is led by the President. The Vice President and Cabinet members are integral to the executive branch, assisting the President in carrying out executive functions and administration. Understanding the distinct roles of each branch of government is crucial for comprehending how the U.S. federal system operates, emphasizing the separation of powers designed to prevent any one branch from becoming too powerful.
