The Massachusetts Democratic Party has filed an ethics complaint against Scott Brown, alleging that Brown has used official resources for campaign purposes.The complaint focuses on footage of Brown’s half-court shot, which appears in a campaign web video but, per the Boston Globe, was shot by one of Brown’s congressional staffers.“By permitting his official staff to engage in campaign related activity while serving in their official capacity, Senator Brown has failed in his responsibility to ensure that the interests of his campaign ‘do not conflict with or detract from official staff duties’ and acted in violation of federal law,” the complaint says.
