Roland Palencia is out as head of California's largest gay rights group, Equality California, gay site first reported on Monday.

“I am stepping down,” Palencia told Karen Ocamb. “We will be having a board meeting and have a transition plan by the end of the week.”

Palencia was selected in May to succeed long-time Executive Director Geoff Kors.

The group did not give a reason for Palencia's quick departure, saying in a press release only that the group was grateful for his service.

“Roland Palencia did important work to build diverse and inclusive coalitions and engage and reconnect our movement,” said board member Cathy Schwamberger. “That work has helped to position our movement to fight back against attacks on the LGBT community and protect advances in equality – the effects of which will impact our movement for years to come. We are grateful for his service to Equality California and his contributions to our movement and wish him the best in all of his future endeavors.”

The move comes just days after the group announced that it would not back a 2012 effort to repeal Proposition 8, California's gay marriage ban.

Last month, Palencia was forced to walk back comments he made about the effort to repeal the FAIR Education Act (also known as SB 48), a law that mandates schools teach about the historical contributions of gay, lesbian, bisexual and transgender people.

“The prospects are not good if this gets to the ballot,” Palencia told reporters during a conference call. “I am not under any illusion.”

In a statement released a few hours later, Palencia expanded on his comments: “We are realistic about how difficult this campaign will be, how hard it will be to win. But we also know that even if we start way behind, a loss is not a foregone conclusion. From our starting place our chances may not look good, but I don't believe it is impossible.”
