An Arizona group, Americans for Responsible Leadership, has made a $11 million donation to a business political action committee propping up an anti-union tax measure and fighting Gov. Jerry Brown's tax initiative. Here are some of the people involved with the group:

--Robert Shaw Graham, 40, a Phoenix investor, is seeking the chairmanship of the Arizona Republican Party -- a post he failed to win in early 2011. The author of an anti-labor book, "Job Killers: An American Dream in Reverse," he also was a candidate in Arizona's 2010 Republican gubernatorial primary. He has given $5,835 to Americans for Responsible Leadership to oppose an Arizona ballot measure to adopt a California-style "top two" primary, aimed at encouraging political moderation.

--Steven Paul Nickolas, 57, a Scottsdale executive in the food and beverage industry who received his bachelor's degree from Claremont College and completed postgraduate work at Claremont and Cal Poly Pomona. He is not known to have contributed money to any political causes.

--Eric Wnuck, 43, a Phoenix executive in medical imaging, was a congressional candidate in the 2010 Republican primary whose biggest political donation was $5,000 to Rep. Jeff Flake, R-Ariz., now running for a U.S. Senate seat.

--Jill Holtzman Vogel, 42, a Virginia state senator and managing partner of Holtzman Vogel Josefiak, which is defending the Arizona group in its fight with the California Fair Political Practices Commission. Holtzman Vogel is the chief counsel for the Republican National Committee and served as counsel to then-presidential candidate George W. Bush and his running mate, Dick Cheney, during the 2000 Florida vote recount.

--Jason Torchinsky, a partner with Holtzman Vogel Josefiak who argued the case for Americans for Responsible Leadership before a Sacramento judge. He's a member of the conservative Federalist Society who served as deputy general counsel to the 2004 Bush-Cheney campaign and deputy general counsel to the 2005 Presidential Inaugural Committee.

--Cathleen West, a partner with Holtzman Vogel Josefiak who signed the incorporation document for Americans For Responsible Leadership.
