New York Mayor Michael Bloomberg says he would "welcome" a stronger effort by President Obama to argue in favor of gay marriage.
Obama has said his views on gay marriage are "evolving," and he has not explicitly endorsed it. His administration has said it will no longer defend the Defense of Marriage Act.
"I would welcome the president to speak out on this," Bloomberg said in response to a question from ABC News at a press conference with more than a dozen other mayors who were advocating for marriage equality.
Philadelphia Mayor Michael Nutter told ABC News after the presser that "you always welcome support on big issues" from Obama. But he said Obama hasn't fallen short of calling for fairness.
"Everyone should be allowed to have their positions evolve as they see fit," Nutter said.
