Arizona election officials say a company listed as the source of mailers in the Nov. 8 recall election of state Senate President Russell Pearce has not made required disclosures.
The four mailers criticize Pearce and favorably describe challenger Jerry Lewis, and the Secretary of State's Office says it appears Citizens United for Progress should have registered and reported its spending.
A letter sent by the office Tuesday requests information from an attorney listed as an agent for Citizens United for Progress. It was incorporated in August and has a Tempe address.
The attorney, Steven Hirsch, did not immediately return a call for comment.
The mailers are another questionable tactic in a race that already saw another candidate withdraw rather than face renewed scrutiny of Pearce backers' support for her candidacy.
