In a Congressional hearing, Representative Jason Chaffetz (R) asks Comey, “How did the Department of Justice, or how did the FBI, view the incident in which Hillary Clinton instructed Jake Sullivan to take the markings off of a document that was to be sent to her?” (This is in reference to a June 17, 2011 email in which Clinton wrote to Sullivan about a classified fax: “Turn into nonpaper w no identifying heading and send nonsecure.”)
Comey answers, “Yes, we looked at that pretty closely. There was some problem with their secure fax machine and there was an email in which she says in substance, take the headers off of it and send it as a non-paper and as we’ve dug into that more deeply, we’ve come to learn that at least this one view of it that is reasonable, that a ‘non-paper’ in State Department parlance means a document that contains things we could pass to another government. So essentially take out anything that’s classified and send it to me. Now it turned out that didn’t happen. We actually found that the classified fax was then sent, but that’s our best understanding of what that was about.” (CNN, 7/7/2016)
