June 9, 2016: State Department lawyers argue they cannot identify which department employees conducted government business on Clinton’s private server.

In a court filing in a civil suit, they argue they cannot do this since the department has never been in possession of the server. It is known that Clinton and her deputy chief of staff had clintonemail.com email accounts on the server, but it is still unclear who else at the department may have. Apparently, Department officials have not tried to check if emails sent from Clinton’s former top aides had email addresses ending in clintonemail.com. (CNN, 6/9/2016)
