“Listen to me now, understand me later.” State Sen. Juan Vargas, D-San Diego, gave a well-received Arnold Schwarzenegger impression, chest heaving and heavy on the former California governor’s thick Austrian accent. Vargas, a former president of external affairs for Safeco Insurance and formerly vice president of corporate legal for Liberty Mutual Group, on Tuesday discussed his experience in state Legislature working for worker’s compensation reform, his current bid for Congress and government oversight of the insurance industry at the IBA West Annual Meeting and Installation of Officers luncheon in San Diego.
