How does the Mann Act apply to legalized brothels in Nevada?

The Mann Act, also known as the White Slave Traffic Act, does not apply to legalized brothels in Nevada.

The Mann Act prohibits the transportation of any woman or girl for the purpose of prostitution or any other immoral purpose across state lines. However, Nevada is one of the few states in the United States where prostitution is legal in certain counties. Therefore, the Mann Act does not apply to women or girls who are transported to Nevada for purposes of prostitution, as long as they stay within the state.
