July 23, 2010: An email forwarded to Clinton includes the name and email address of at least one secret CIA official.

A US official whose name is later classified sends an email to at least two dozen other US officials. Most of their names will later be classified as well. At least one redacted recipient’s name is that of a secret CIA official. The email concerns a recent WikiLeaks release of classified documents and includes an attachment that has a statement by senior Defense Department officials and relevant talking points. Clinton aide Jake Sullivan forwards the email to Clinton. (US Department of State, 2/26/2016)
