FBI Chief Leaker James Comey, in testimony from June 8, at The Hill:
“So you didn’t consider your memo or your sense of that conversation to be a government document?,” Sen. Roy Blunt (R-Mo.) asked Comey on June 8. “You considered it to be, somehow, your own personal document that you could share to the media as you wanted through a friend?”
“Correct,” Comey answered. “I understood this to be my recollection recorded of my conversation with the president. As a private citizen, I thought it important to get it out.”
The Hill, 7/9/2017:
Comey’s private memos on Trump conversations contained classified material
More than half of the memos former FBI chief James Comey wrote as personal recollections of his conversations with President Trump about the Russia investigation have been determined to contain classified information, according to interviews with officials familiar with the documents. -snip-
Comey testified last month he considered the memos to be personal documents and that he shared at least one of them with a Columbia University lawyer friend. He asked that lawyer to leak information from one memo to the news media in hopes of increasing pressure to get a special prosecutor named in the Russia case after Comey was fired as FBI director.
So, the documents contained secrets which should never have been given to a friend, to give to a reporter. They were created to be leaked — or to protect him if he was ever fired. And he was. Good riddance.
