Hillary Clinton email controversy

In March 2015, it became publicly known that Hillary Clinton, during her tenure as United States Secretary of State, had used her family's private email server for official communications, rather than official State Department email accounts maintained on federal servers. Those official communications included thousands of emails that would retroactively be marked classified by the State Department.

The controversy unfolded against the backdrop of Clinton's 2016 presidential election campaign and hearings held by the United States House Select Committee on Benghazi. Some experts, officials, and members of Congress have contended that her use of private messaging system software and a private server violated State Department protocols and procedures, as well as federal laws and regulations governing recordkeeping. In response, Clinton has said that her use of personal email was in compliance with federal laws and State Department regulations, and that former secretaries of state had also maintained personal email accounts, though not their own private email servers.

After allegations were raised that some of the emails in question contained classified information, the Federal Bureau of Investigation (FBI) initiated an investigation regarding the origin and handling of classified emails on Clinton's server. The FBI Report found that some of the emails originated in five other intelligence agencies. The FBI found that all classified emails on Clinton's server were stored and sent from "unclassified systems", violating the same policies as those on Clinton's personal server.

FBI Director James Comey identified 110 emails as containing information that was classified at the time it was sent, including 65 emails deemed "Secret" and 22 deemed "Top Secret". None of these had classification markings. However, as noted in Clinton's non-disclosure agreement, unmarked classified information should be treated the same as marked classified information. An additional three email chains contained "portion markings", simply a "(C)" indicating "Confidential" in front of one or more paragraphs. These were not included in Comey's list of 110 because the State Department failed to confirm they were classified at the time they were sent. Clinton told the FBI she did not know the meaning of "(C)". Nearly 2,100 emails on the server were retroactively marked as classified by the State Department.
