On March 31, a bill overhauling campaign finance passed by the Arizona Legislature was signed into law by Gov. Doug Ducey. Among the changes to the state’s law, Senate Bill 1516 allows groups registered with the IRS as “social welfare” organizations to withhold disclosing donor information, removes spending caps on expenditures for political fundraisers, and allows for candidate to candidate transfers of campaign funds.

“When it comes to free speech and participation in the democratic process, our laws should reflect the goal of making it easier for more citizens to engage. That’s what this reform package does,” the Albuquerque Journal reports Ducey as saying. The law becomes effective January 1, 2017.
