(Portland, OR) -- GOP U.S. Senate candidate Monica Wehby says a former campaign staffer is responsible for plagiarism that appeared in some of her issue documents. The content was removed from Wehby's campaign website after it was reported that some of the passages were copied from a report by Republican Senator Rob Portman of Ohio and from a plan by a GOP congressional candidate from California. "The Oregonian" reports that the former staffer likely in question, ex-Wehby campaign manager Charlie Pearce, has denied any involvement with the plagiarism. Pearce is now handling Dennis Richardson's gubernatorial campaign.
