The office of Ohio’s Republican attorney general says it has appointed an outside law firm to investigate a Democratic state representative…amid claims the lawmaker engaged in a pattern of erratic and abusive behavior toward other legislators, staff and constituents for months. The investigation into Rep. Elliot Forhan, a Cleveland-area lawyer who was elected to the Ohio House last fall, comes at the request of Republican House Speaker Jason Stephens. It follows months of alleged hostile behavior, according to a memo from House Minority Leader Allison Russo last week.
