Sid Blumenthal is a Clinton confidant, reporter, and Clinton Foundation employee in the years Clinton is secretary of state. The interview will remain secret until it’s mentioned in a September 2016 FBI report.

The FBI identified at least 179 out of the over 800 emails that Blumenthal sent to Clinton containing information in an intelligence memo format. The State Department determined that 24 Blumenthal memos that contained information currently classified as “confidential,” as well as one classified as “secret”  both currently and when it was sent.

Blumenthal tells the FBI that the content of the memos was provided to him from a number of different sources, including former US government officials and contacts, as well as contacts within foreign governments.

(In one email to Clinton, Blumenthal mentioned intelligence that he said came from an active US official, but apparently the FBI doesn’t ask him about this. The FBI report also will not mention emails in which Clinton sent Blumenthal classified information, despite him having no security clearance.)

Blumenthal’s memos contained a notation of “CONFIDENTIAL”  in all capital letters. He claims this meant the memos were personal in nature and didn’t refer to the US government category of classified information at the “confidential” level.

Blumenthal claims he was not tasked to provide this information to Clinton, but he sent the emails because he thought they could be helpful. (Federal Bureau of Investigation, 9/2/2016)
