PORTLAND- The Maine Ethics Commission will not pursue a complaint from a Portland man that Democratic State Rep. Ben Chipman sent a mailer to voters without disclosing financing.

A spokesman for the commission says it voted unanimously on Wednesday not to conduct further investigation into the complaint.

Steven Biel had contended that a mailing supporting Chipman was not exempt from financial disclosure requirements. Biel has been supporting Democratic Rep. Diane Russell, who is running for a state senate seat that Chipman is also seeking.

Chipman says he wasn’t surprised the ethics panel isn’t pursuing the complaint any further. He says his campaign worked with ethics commission staff “every step of the way” on the mailing and followed its guidance.
