(CNN) - Former GOP presidential candidate Mitt Romney has joined calls from key Republicans urging Arizona Gov. Jan Brewer to veto legislation that critics say would codify discrimination against gays and lesbians in that state.
Romney's message followed tweets from Arizona's Republican senators, John McCain and Jeff Flake, urging Brewer to reject SB1062, which would allow businesses in the state to refuse service to gays and lesbians based on religious beliefs.
By contrast, President Barack Obama, who has evolved into one of the nation's leading proponents of gay rights, has yet to personally weigh in on the legislation.
Asked about the Arizona bill by reporters, White House Spokesman Jay Carney described SB 1062 as a "pretty intolerant proposed law."
"As a practice, we don't generally weigh in on every piece of legislation under consideration in the states," Carney said.
"I think the President's position on equality for LGBT Americans and opportunity for all is very well known. And he believes that all of us, regardless of sexual orientation or gender identity should be treated fairly and equally, with dignity and respect," Carney added.
