COLUMBIA, S.C. — South Carolina’s top legislators declined to provide emails and schedules requested by The Associated Press, citing the public records exemption the General Assembly carved for itself in state law. Gov. Nikki Haley, who has no such exemption, released a detailed public schedule and provided access to more than 450 emails, though they show she conducts no business through government email subject to the Freedom of Information Act. Several hundred constituent emails to Haley contained a wide array of requests, complaints and commendations.
