Arizona Governor Signs Tempe's 'Dark Money' Ban

Gov. Doug Ducey signed off on a voter-approved measure to eliminate secret political spending in Tempe elections, but his office also issued a word of caution: the approval is based on current law, not new rules that will take effect in August.

The state Legislature outlawed cities from requiring political non-profits to disclose their donors, among other things. Ducey, a major benefactor of dark money spending in 2014, signed the bill in April.  

"Please note that this approval is based on the law as it is at the time of the approval and does not take into account any changes that have not yet taken effect from this legislative session," Ducey's Deputy General Counsel, Anni Foster, said in her letter to the city.
