Committee members may not receive any compensation for the performance of their official duties. Voting members may be reimbursed for travel expenses and meals and lodging expenses in connection with their official duties at the same rate and in the same manner as are elected officials and employees of the state, with payment to be made by the department of veterans’ affairs and the veterans’ home to each of their respective subcommittee members incurring the expenses. The payment must be made by warrant-check drawn by the office of management and budget upon the submission of a proper voucher to it, signed by the commissioner of veterans’ affairs or the administrator of the veterans’ home, as the case may be.
