The budget and audit committee may meet during sessions of the legislature and during the interim between sessions at such times and places in the state as the chairman may determine. Members may receive, for the minimum time required to get to and from meetings and for the period while attending meetings, the same travel and per diem allowances provided by law for members of the legislature when attending sessions, except that members of the committee receive no per diem during legislative sessions other than the per diem allowance paid to other members of the legislature.
