According to IndyStar, when Vice President Mike Pence was still governor of Indiana, he used his personal AOL email account for public business matters, including sensitive matters and issues of national security.

The emails, which could be viewed through a public records request, came from the Pence’s personal account, and includes security issues at Pence’s home and Indiana’s “response to terror attacks across the globe.”

Last summer, the vice president’s email account was hacked causing concerns about the content on his private account. Advocates for government transparency are worried because emails that were sent from a personal account are not available to a public records request.

Using a private email server for official government business was a big talking point in Trump’s campaign. They accused their Democratic opponent, Hillary Clinton, of breaking the law when she did it and prompted chants of “Lock her up!” during the rallies.

During an interview on “Face the Nation”, Pence told host John Dickerson that the FBI’s decision to renew their investigation after previously canceling it was the right thing to do.

“That original decision was really incomprehensible,” he said. “To arrive at a place where even in his testimony before the Congress, and in that long press conference that he gave … that literally Hillary Clinton had classified information on a private server that she said she didn’t have … that, to me, is the kind of double standard that the American people are weary of.”
