The rabbi who defied Texas' same-sex marriage ban and wed a lesbian couple last week led the morning prayer in the Republican-dominated Texas House on Wednesday, catching supporters of the prohibition off-guard.

Rabbi Kerry Baker didn't reference the nuptials, which are being challenged by the state attorney general, but urged lawmakers to pay special attention to people who are marginalized and to treat everyone equally.

"It's not enough to do what is good for the majority, but to do what is good for all of us," Baker said.

Baker then stood for a photo with Republican House Speaker Joe Straus, who later acknowledged he was unaware Baker was involved in the wedding, and Rep. Elliott Naishtat, the Austin Democrat who introduced Baker. Naishtat subsequently said he intentionally omitted details of Baker's role in the wedding during his introduction.

"This is a place where we believe in free speech, and that begins with a prayer each day," Straus said after being told Baker oversaw the ceremony.

Naishtat said he hadn't heard a word of opposition from other House members.
