John Jay, in a letter to George Washington, opined that the postal service should not be burdened with the responsibility for handling newspaper delivery, and also suggested that the Post Office be placed under the supervision of the executive branch (a suggestion which later led to the creation of the Post Office Department). Thomas Jefferson feared that the postal service would become a source of patronage and a waste of money. Jefferson also expressed doubt at granting Congress the power to designate post roads, as he considered road building to be a state responsibility.
