The Cabinet includes one member who is not the head of a department, the Vice President of the United States.

Explanation:

The United States Cabinet is comprised of the highest level executive branch officials in the federal government. The first cabinet was assembled by President George Washington by appointing four of his closest collaborators - Secretary of State Thomas Jefferson, Secretary of the Treasury Alexander Hamilton Secretary of War Henry Knox and Attorney General Edmund Randolph - who assisted him in his duties. Later, the cabinet expanded with the introduction of new officials appointed as department secretaries. The Vice President is also a cabinet member.

Except for the Vice President, Cabinet members are appointed by the President, but must then be confirmed by a simple majority by the Senate.
