Upon the receipt by a Governor-elect of the tentative budget provided for by § 4-79, he shall hold such hearings thereon as may be requested by budgeted agencies or may be considered by him desirable. He may require the attendance at such hearings of the heads and other officers of all budgeted agencies and the giving by them of such explanations and suggestions as they are called upon to give or as they desire to offer in respect to items of requested appropriations or estimated revenue in which they are interested. The Secretary of the Office of Policy and Management shall arrange a schedule of the time and place of such hearings to suit the convenience of the Governor-elect and shall give notice thereof to the respective budgeted agencies interested in such hearings. The secretary or his representative shall attend all such hearings and shall give such advice and assistance to the Governor-elect as that officer requests. The sum of twenty-five thousand dollars shall be made available by the Comptroller from the unappropriated resources of the state General Fund to the Governor-elect upon his request to the Comptroller. This sum may be used by him as he deems proper and necessary to meet the expenses of transition prior to his inauguration.
