GEORGE STEPHANOPOULOS: Y– you also write that you– you knew from the start that the Clinton case was unlikely to be prosecuted. Some of your critics, including President Trump, think that– that you brought a prejudgment to the case?
JAMES COMEY: Yeah. There's wrong– what– what the F.B.I. brought to the case– folks forget I didn't actually do this investigation. I supervised an organization that did it, is a knowledge about how these cases are handled in the counterespionage world. That's the world where mishandling of classified information is investigated. And so we have a 50 year history of knowing what will the Department of Justice prosecute?
They'll prosecute cases like David Petraeus'. But they're very unlikely to prosecute a case unless you can show the person, like Petraeus, clearly knew they were doing something they shouldn't do. There's evidence of obstruction of justice or disloyalty to the United States, spy– indications.
But without those, sloppiness, even extreme sloppiness, is handled through administrative discipline. Somebody is not prosecuted. And I've gone through 50 years of cases. I don't know of a case where anyone has ever been prosecuted for just being careless, even extremely careless. And so when the case was open, we know that history.
And so the investigators knew that, unless they found something that was a smoking gun, where someone told Secretary Clinton, "You know, you shouldn't be doing this," or where she acknowledged it or where somehow there's an indication of her obstructing justice, the case was unlikely to be prosecuted.
