Apple, which is building a glass plant in Mesa that's slated to create hundreds of jobs, said Monday that it, too, was urging Brewer to veto SB1062.
The state Chamber of Commerce and Greater Phoenix Economic Council have come out against the bill as well, and local businesses in Tucson and Phoenix have also taken strong stances.
Scott Koehler of Phoenix FASTSIGNS has printed off dozens of signs saying "Open for business to everyone," which he's giving away to businesses. In Tucson, Rocco's Little Chicago Pizzeria took to its Facebook page to post a photo of a sign reading, "We reserve the right to refuse service to Arizona legislators."
But while opposition to the bill has been loud -- and has included the condemnations of John McCain and Jeff Flake, the state's Republican U.S. senators -- there are those who say the bill is vital in a nation that has increasingly turned hostile toward religion.
Whom does it protect?
Said the Center for Arizona Policy's Herrod, "Simply put, the fear-mongering from opponents is unrelated to the language of the bill, and proves that hostility towards people of faith is very real. It's a shame we even need a bill like this in America. But growing hostility against freedom in our nation, and the increasing use of government to threaten and punish its own citizens, has made it necessary."
State Sen. Al Melvin, a hopeful to succeed Brewer, told CNN's Anderson Cooper that Arizona was a "people friendly" state and that SB1062 was merely a "pre-emptive" measure that would prevent attacks on religion in the future.
"All of the pillars of society are under attack in the United States: the family, the traditional family, traditional marriage, mainline churches, the Boy Scouts, you name it," he said.
Asked if he could cite specific examples of attacks on Arizonans' freedom of religion, Melvin replied, "Not now, no, but what about tomorrow?"
Pressed further about whether the bill could be used to deny service to divorcees or unwed mothers on religious grounds, he scoffed.
"I think you're being farfetched," he told Cooper. "Who would discriminate against them? I've never heard of discrimination against people like that. ... I don't know of anybody in Arizona that would discriminate against a fellow human being."
Arizona constitutionally outlawed same-sex marriages in 2008, and legal experts say nothing in present Arizona law would prevent a business owner from discriminating against gays and lesbians, making SB1062 unnecessary.
Brewer alluded to these provisions in an interview after SB1062 was passed last week.
"I think anybody that owns a business can choose who they work with or who they don't work with," she said.
While Arizonans on both sides of the issue, as well as the nation at large, keep keen eyes on Phoenix as Brewer ponders her decision, the governor has hinted that the issue, for her, may come down to whether the ban or protection of freedom -- depending on how you view it -- needs to be enshrined in state law.
"I don't know that it needs to be statutory. In my life and in my businesses, if I don't want to do business or if I don't want to deal with a particular company or person or whatever, I'm not interested. That's America. That's freedom."
