Fifty same-sex couples from Louisiana will gather on the state Capitol steps Saturday for a marriage equality campaign dubbed “Louisiana Loves.”

According to LGBT advocacy groups Capital City Alliance and Equality Louisiana, participants will do video interviews and shoot photos on the iconic steps of the state Capitol. The photos will become part of a commemorative book marking what advocates hope to be the legalization of same-sex marriage in Louisiana.

“Many same-sex couples stay together for years facing not only discrimination, but also many other cultural and legal challenges. Despite the challenges, these couples have been courageous in the face of opposition and remained deeply committed to building happy lives and families together,” Equality Louisiana and CCA wrote in a news release.

Louisiana voters in 2004 adopted a constitutional amendment to ban gay marriage and the recognition of same-sex marriages that take place in other states. Lawsuits that threaten to upend that ban are pending on the state and federal level, and the U.S. Supreme Court could weigh in on the issue by June.
