That’s my reading of this interview on 60 Minutes (emphasis added).

Steve Kroft: Did you know about Hillary Clinton’s use of private email server–

President Barack Obama: No.

Steve Kroft: –while she was Secretary of State?

President Barack Obama: No.

Steve Kroft: Do you think it posed a national security problem?

President Barack Obama: I don’t think it posed a national security problem. I think that it was a mistake that she has acknowledged and– you know, as a general proposition, when we’re in these offices, we have to be more sensitive and stay as far away from the line as possible when it comes to how we handle information, how we handle our own personal data. And, you know, she made a mistake. She has acknowledged it. I do think that the way it’s been ginned-up is in part because of– in part– because of politics. And I think she’d be the first to acknowledge that maybe she could have handled the original decision better and the disclosures more quickly. But–

Steve Kroft: This administration has prosecuted people for having classified material on their private computers.

President Barack Obama: Well, I– there’s no doubt that there had been breaches, and these are all a matter of degree. We don’t get an impression that here there was purposely efforts– on– in– to hide something or to squirrel away information. But again, I’m gonna leave it to–

Steve Kroft: If she had come to you.

President Barack Obama: I’m going to leave it to Hillary when she has an interview with you to address all these questions.

How does he know all this? Has he been briefed by the FBI about the investigation? There’s been no indication from those entities that the investigation is concluded.

It’s always questionable when a President comments on a pending investigation, precisely because it can been seen as interference.

I think he sent a loud and clear message to the Justice Department — put this one to bed, it’s all politics.
