The Tennessee governor can veto laws passed by the Tennessee General Assembly and has line-item veto authority for individual spending items included in bills passed by the legislature. In either situation, the governor’s veto can be overridden by a simple majority of both houses of the legislature. If a governor exercises the veto authority after the legislature has adjourned, the veto stands.[1] It is uncommon for Tennessee governors to use their veto power, probably because it is so easy for the General Assembly to override a veto.[6]
