Definition: In 1910, Congress passed the Mann Act which makes it a federal crime to transport individuals under the age of 18 across state lines to engage in any sexual activity.
The original intent of the law was to stop prostitutes from being moved from one locale to another or out of the country. It now also applies to an adult taking a consensual minor to another state.
