Vice President Mike Pence used a private AOL account to conduct official business in his former position as the governor of Indiana, according to public records. And at one point, the account was hacked and used to send fraudulent emails seeking money from his contacts.
Pence used the account to communicate with advisers about issues including homeland security in Indiana and the security of the gates at the governor's mansion, The Indianapolis Star reports.
The newspaper says it obtained 29 pages of email records from current Indiana Gov. Eric Holcomb's office in response to a public records request.
Under Indiana law, public officials are allowed to use personal email accounts and the practice can help them avoid using official accounts to conduct political business. As the Star notes, the law is "generally interpreted" to require public officials to save any emails related to official business in order to follow open records laws. A Pence spokesman says the vice president complied with that requirement.
