Mike Pence used private email for state business

"Vice President Mike Pence routinely used a private email account to conduct public business as governor of Indiana, at times discussing sensitive matters and homeland security issues. In fact, Pence's personal account was hacked last summer.Pence communicated via his personal AOL account with top advisers on topics ranging from security gates at the governor’s residence to the state’s response to terror attacks across the globe. In one email, Pence’s top state homeland security adviser relayed an update from the FBI regarding the arrests of several men on federal terror-related charges.Furthermore, advocates for open government expressed concerns about transparency because personal emails aren't immediately captured on state servers that are searched in response to public records requests."
