Attorney General of Alabama Luther Strange has already announced he will defend the marriage equality ban.
«As attorney general, I will vigorously defend the traditional definition of marriage as between one man and one woman,» Strange said in a statement.
«That has been the definition of marriage for the history of Western civilization, and Alabamians overwhelmingly voted to incorporate it into our laws.»
