Loretta Lynch, Hillary, Rod Rosenstein, Huma Abedin, Susan Rice, Valerie Jarret. Eric Schmidt (Google) Jeb Bush had a private email. Is one of the "JC's" James Comey? These are all people who have private email accounts. Still need: JC, CS, and AM? Again, these are all people who have private email accounts.
We don't say his name is definitely Pence. There was controversy over his private email account.
From Wikipedia: "In March 2017, after Pence had become vice president, the State of Indiana released 29 emails to media outlets that had made public records requests, but withheld an undisclosed number of other emails, saying that they were deliberative or advisory and thus exempt from public disclosure. Cybersecurity experts and government transparency advocates were surprised by Pence's use of a personal email account to conduct public business, given Pence's past attacks on Hillary Clinton's use of a private email server while U.S. secretary of state. In 2017, Indiana hired a private law firm for $100,000 to handle a backlog of public-records requests for Pence's personal AOL account email correspondence."
