Washington established a Cabinet even though it was not mentioned in the Constitution.

The Cabinet of the United States was created by President Washington at the beginning of its first term, as an advisor and consultative body for the president, made up of the secretaries of the Department of War, the Department of the Treasury, and the Department of State, in addition of the Attorney General and the Vice President.

This Cabinet was not explicitly stated in the constitutional text, but its creation was protected by different principles inserted in it.
