On May 18, Arizona Gov. Doug Ducey signed campaign finance legislation advancing the effective date of implementation of some of the changes to June of this year. House bills 2296 and 2297 complement Senate Bill 1516, another campaign finance bill signed into law in March. The legislation also includes criminal penalties left out of the earlier Senate bill.

The package of legislation is controversial among many because of the relaxation of disclosure by some entities involved in political activity.
