BOISE -- Three Boise Democratic candidates sent voters a campaign newsletter emblazoned with Idaho's official seal, though the secretary of state's office discourages people from using the seal on anything but official state business.
Sen. Elliot Werk, Rep. Sue Chew and candidate John Gannon distributed the mailer Monday to voters.
It highlights what the candidates say are Republican ethics transgressions.
But Tim Hurst, deputy secretary of state, says Idaho's seal should only be used for official business, not campaigning.
Using it for political purposes could imply Idaho's endorsement, when none exists.
Werk indicated he wasn't too familiar with the mailer and pledged to look into it.
In 2011, Chew was previously warned for raising opposition to public schools chief Tom Luna's disputed reforms via a mass mailing from her state email account.
