In the latest challenge to Alabama's ban on gay marriage, a lesbian couple is suing the state over recognition of their marriage, performed in Massachusetts. April and Ginger Aaron-Brush of Birmingham filed the lawsuit Tuesday in federal court in Birmingham.

The lawsuit asks a judge to declare the ban unconstitutional and require Alabama to recognize same-sex marriages performed validly in other states.

The American Civil Liberties Union is representing the couple.
