FBI documents revealed that President Obama used a pseudonym in his mail conversations with Hillary Clinton. The FBI documents were released last Friday.
The revealed document is one of the many documents that have been released from the investigation into Hillary Clinton her private email server.
The politico.com stated that the report does not provide any more details on the particular content of the email exchange between President Obama and Hillary Clinton.
The report doesn't provide more details on the contents of that particular email exchange, but says it took place on June 28, 2012, and had the subject line: "Re: Congratulations." It may refer to the Supreme Court's ruling that day upholding a key portion of the Obamacare law.
