The "governor's cabinet" has evolved through custom and tradition loosely patterned after the United States president's cabinet. Each member of the president's cabinet has a constitutional duty to provide opinions as the principal officer of an executive department when required by the president. U.S. const., art. II, section 2. There is a similar provision in the Kansas constitution. As such, cabinet members serve as advisors to the governor. The members of the current governor's cabinet include the secretaries of various state departments who are appointed by the governor subject to the confirmation of the senate and serve at the pleasure of the governor. In our opinion, the legislature may require that the secretary of the board of agriculture serve as a member of the governor's cabinet because as a member of the executive department she is already subject to the governor's request for information regarding her duties.
