Minn. Stat. § 15.057

No state department, bureau, or division, whether the same operates on funds appropriated or receipts or fees of any nature whatsoever, except the Department of Veterans Affairs, the Department of Transportation, the Department of Employment and Economic Development, the Department of Agriculture, the Game and Fish Division, State Agricultural Society, and Explore Minnesota Tourism shall use any of such funds for the payment of the salary or expenses of a publicity representative. The publicity representative for the Department of Agriculture must not be an elected official or candidate for public office. The head of any such department, bureau, or division shall be personally liable for funds used contrary to this provision. This section shall not be construed, however, as preventing any such department, bureau, or division from sending out any bulletins or other publicity required by any state law or necessary for the satisfactory conduct of the business for which such department, bureau, or division was created.
