The man who represents Columbia County in Congress now says he will resign amid the political fallout from an 18-year-old woman’s allegations of an unwanted sexual encounter with him. Democratic leaders had requested a House Ethics Committee investigation of the conduct of Congressman David Wu, and pressure had been growing for him to resign. In a statement issued late yesterday morning, Wu said he would put the wellbeing of his children first, and says that he plans to step away from Congress after the debt ceiling issue is settled. Attention now turns to finding Wu’s replacement; Oregon Governor John Kitzhaber announced yesterday that plans are already in the works to conduct a special election to select Wu’s replacement. Several possible contenders are already lining up, including several people who’d already announced plans to run for the seat next year. Among those is current Oregon state representative Brad Witt of Clatskanie, along with Oregon Labor Commissioner Brad Avakian and businessman Rob Miller.
