The Scottsdale Area Chamber of Commerce was recently hit with a campaign finance complaint, according to this report.

Seven Scottsdale mayor and council candidates filed a complaint with the county attorney’s office Monday alleging the Scottsdale Area Chamber of Commerce illegally used corporate funds to advocate the election of the four other candidates in the mayor and council races.

The complaint addressed to Maricopa County Attorney Andrew Thomas requests a criminal investigation of the chamber’s campaign activity, which includes distributing a four-page color glossy mailer and running a television commercial highlighting the four candidates it’s supporting in the Sept. 2 election. It alleges a potential felony violation.

A chamber executive defended the ad campaign Tuesday, saying it is legal.
