COOPER: So, let me ask you about that because David Axelrod was very critical of the way that you and your campaign handled sharing your diagnosis with the public. He tweeted : "Antibiotics can take care of pneumonia. What's the cure for an unhealthy penchant for privacy that repeatedly creates unnecessary problems?"

Why not just say on Friday as you said apparently to Senator [Chuck] Schumer on Sunday, you know, "I have pneumonia, folks, I’m going to power through it"? Why keep it a secret?

CLINTON: Well, I just didn't think it was going to be that big a deal. You know, I know Chuck said today he didn't tell anybody. It's just the kind of thing that if it happens to you and you're a busy, active person, you keep moving forward.

And, you know, I think it's fair to say, Anderson, that people know more about me than almost anyone in public life. They've got 40 years of my tax returns, tens of thousands of emails, a detailed medical letter report, all kinds of personal details.
