Clinton is sent an email by State Department official Monica Hanley regarding a phone call to new Malawi president Joyce Banda. All the text of the email will later be redacted except for the first few lines, one of which states, “(C) Purpose of Call: to offer condolences on the passing of President Mukharika and congratulate President Banda on her recent swearing in.” The “(C)” is an official code known as a “portion marking,” and it indicates the information is classified at the “confidential” level.
In June 2016, Fox News will report that an unnamed US government source claims “there are other Clinton emails with classified markings, or marked classified, beyond” this email, but presumably those markings are in later-redacted portions of the emails. Clinton does not flag the email for having classified information in an insecure channel, but merely makes a brief comment that the timing of the phone call works for her.
Also in June 2016, Clinton spokesperson Brian Fallon will be asked directly about the email. However, he will ignore the direct evidence the email was marked classified at the time by saying, “The fact that this email was classified after the fact suggests again that agencies in the government tend to err on the side of classifying even routine matters of diplomacy.” (Fox News, 6/11/2016) (US Department of State, 1/29/2016) (LawNewz, 6/11/2016)
