Olson, who was solicitor general under Bush, and attorney David Boies successfully fought Proposition 8, the California ballot referendum that prevented gay marriage, in court.

While more individual GOP lawmakers have been endorsing same-sex marriage, it is not the mainstream view in the party and several top Republicans -- including Speaker John BoehnerJohn Andrew BoehnerIs Congress retrievable?

The Supreme Court last week left a lower court ruling intact that knocked down Proposition 8, and in a separate 5-4 decision knocked down key provisions in the federal Defense of Marriage Act.

“These decisions signal equality for so many of our citizens [who] for so long have been discriminated against,” Olson said.

The high court let the lower court Proposition 8 decision stand on procedural grounds.

An opponent of same-sex marriage, speaking on the same CBS show, said the court’s choice – for now – not to extend constitutional protections for same-sex marriage nationwide was a “silver lining.”

“That buys us a little time,” said Tony Perkins, head of the conservative Family Research Council, who said that over time Americans will come to see same-sex marriage as a “Pandora’s box.”

Same-sex marriage remains barred in roughly three-dozen states. “I think you are going to see more of a containment strategy going forward,” said Perkins, who slammed the Supreme Court.

“Essentially what the court has done is they have dragged we the people from behind the wheel of this Republic and they have car-jacked the nation,” he said.
