Vanna White veto n. a form of line-item veto that permits an elected official to strike single letters in legislation. Editorial Note: This term is specific to Wisconsin, where this type of veto—also called a pick-a-letter veto and similar to the digit veto, which allowed the striking of single numerals—is no longer permitted by state law. Etymological Note: Vanna White is hostess for the game show “Wheel of Fortune,” where she is responsible for revealing letters on a large board at the direction of contestants.
