Haley, a Republican as is Fallin, was invited because she opposed the National Labor Relations Board's attempt to stop Boeing from building a manufacturing plant in South Carolina.
Individual tickets for the event range from $250 to $1,000. Tickets went on sale Wednesday and about 100 already have been sold, Rhoades said. Table sponsor tickets also are being sold.
“The Goldwater Institute promotes the ideas of constitutional liberty and freedom, things that we hold very dear in Oklahoma,” Fallin said. “It's not only an honor; it's a great opportunity to tell the Oklahoma story to a national audience.”
Previous speakers include Wisconsin Gov. Scott Walker and New Jersey Gov. Chris Christie, both Republicans.
The Goldwater Institute will pay for Fallin's transportation to Phoenix, said Alex Weintz, Fallin's communications director.
Fallin will leave Phoenix for the Republican Governors Association annual conference Nov. 14-16 in Las Vegas. Those costs will be paid from the governor's campaign funds, he said.
Fallin also plans to attend a National Governors Association meeting in San Diego later that week. She is vice chairman of the bipartisan organization of the nation's governors. The trip to San Diego and the return flight to Oklahoma City likely will be paid with state funds, Weintz said.
The state usually pays for trips to the National Governors Association because the governor attends in an official capacity as the state's chief executive.
