What cabinet members must get Senate approval?

Cabinet members who lead the executive departments of the U.S. government, such as the Secretary of State, Secretary of Defense, and Secretary of the Treasury, must receive Senate approval upon nomination by the President. Additionally, other key positions like the Attorney General and the Secretaries of various departments, including Education and Health and Human Services, also require Senate confirmation. This process ensures a system of checks and balances between the executive and legislative branches.
