Mitt Romney is the latest big-name Republican to call for Arizona Gov. Jan Brewer (R) to veto a controversial bill allowing businesses to decline service to gay customers if they feel it violates their religious rights.

Romney tweeted his opposition late Tuesday afternoon:


Sens. Jeff Flake (R-Ariz.) and John McCain (R-Ariz.) have also called for a veto, as have the state's top GOP governor candidates and some legislators who voted for the bill.

Brewer told CNN on Monday night that she is reviewing the bill and will "do the right thing."
