Answer:
The presidential cabinet was not a part of the Constitution in 1789, but rather was created by President Washington.
Step-by-step explanation:
The first president of the United States, George Washington, had quickly identified the need for a cabinet. One of his first acts was to arrange for the establishment of the Secretaries of Foreign Affairs (renamed the Department of State a little later with extended powers) Finance and War. These ministries should be run by officials called secretaries, directly subordinate to the president.
George Washington's first cabinet consisted of Secretary of State Thomas Jefferson, Finance Minister Alexander Hamilton, Secretary of War Henry Knox, and Attorney General Edmund Randolph.
