The concept of Martin Luther King Jr. Day as a holiday was promoted by labor unions. After King’s death, U.S. Representative John Conyers and U.S. Senator Edward Brooke introduced a bill in Congress to make King’s birthday a national holiday. The bill first came to a vote in the U.S. House of Representatives in 1979; however, it fell five votes short of the number needed for passage. Two of the main arguments mentioned by opponents were that a paid holiday for federal employees would be too expensive and that a holiday to honor a private citizen would be contrary to longstanding tradition, as King never held public office. At the time, only two other figures had national holidays honoring them: George Washington and Christopher Columbus.
