After Clinton’s email scandal becomes public in March 2015, The State Department will request all work-related emails from four of Clinton’s top aides: Cheryl Mills, Huma Abedin, Jake Sullivan, and Philippe Reines. The emails will be turned over between June and August 2015.
A department analysis will determine that all four aides frequently used personal email accounts for work matters, although they had government email accounts and sometimes used those as well. The combined work-related personal emails from the four of them will total nearly 72,000 printed pages. One of the four sends and receives 9,585 work emails using a personal account while Clinton is secretary of state, though it isn’t clear which one. That person averages nine work emails from that account per work day.
In May 2016, the department’s inspector general will conclude that, just like Clinton, “these [four aides] failed to comply with department policies… because none of these emails were preserved in department recordkeeping systems prior to [being handed over] in 2015.” (US Department of State, 5/25/2016)
