An aide to Democrat Tom Steyer in South Carolina resigned after accessing volunteer data collected by rival Kamala Harris, the billionaire activist’s campaign said Monday. Last month, Dwane Sims was announced as Steyer’s deputy state director in South Carolina, which holds the first primary in the South. A month earlier, Sims had been working as data director for the South Carolina Democratic Party, a role in which he had access to proprietary campaign information.
