Maine Democrats are renewing their call for the state attorney general to release his findings into the investigation of state Treasurer Bruce Poliquin. State Rep. Mark Dion, a Portland Democrat, has asked the AG whether Poliquin's proposed expansion of his Popham Beach Club in Phippsburg violates constitutional provisions that bar the treasurer from engaging in business activities. Poliquin maintains he has not violated the business ban, but Dion says evidence he has uncovered contradicts that claim.
