An unnamed US official claims that top Clinton aides including Cheryl Mills, Huma Abedin, Philippe Reines, Jake Sullivan, and Patrick Kennedy were CCed on at least some of those emails. (The Hill, 2/10/2016)
Jake Sullivan, Clinton’s top national security and foreign policy staffer, sent 215 classified emails to Clinton, more than anyone else. (The Washington Post, 3/5/2016) He is said to be the author of at least one of the emails sent to Clinton that was later deemed “top secret,” and he may be responsible for others.
Politico reports, “Sullivan both initiated email conversations and also forwarded along messages with sensitive information, and he sometimes added additional content on the email chains in question, according to [our] sources.” As a result, Sullivan could face extra scrutiny from FBI investigators.
Another source says about three of Clinton’s top aides sent her highly classified material. (Politico, 2/10/2016)
