In 1942, Michigan Senator Arthur H. Vandenberg introduced Senate Joint Resolution 166 which would have amended the U.S. Constitution to extend the vote to citizens 18 years of age or older. Although not ratified at the time, the proposal came up again during the Vietnam War. The 26th Amendment was ratified on July 1, 1971 after being passed by Congress just a few months earlier. Although not necessary for the amendment to become law, President Richard Nixon, accompanied by several 18-year old witnesses, signed the amendment on July 5, 1971.
