(CNN) -- All signs indicate Arizona Gov. Jan Brewer will likely veto politically-charged legislation that supporters say promotes religious freedom and opponents contend discriminates against gays and lesbians.

Brewer did not signal her intention either way in an exclusive interview with CNN on Monday at the National Governors Association meeting in Washington.

"I can assure you, as always, I will do the right thing for the state of Arizona," she said.

But some Arizona Republicans who know her well say they are confident those comments mean Brewer will almost surely reject the bill that is generating nationwide controversy.

The Republican-led measure would allow Arizona business owners to deny service to gay and lesbian customers as long as they assert their religious beliefs.

Brewer is scheduled to return to Arizona on Tuesday, and a source tells CNN those familiar with her thinking say she will likely spend at least one full business day in the state before acting.

"I'm going to go home, and when I receive the bill, I'm going to read it and I'm going to be briefed on it. We have been following it. And I will make my decision in the near future," Brewer told CNN.
