Appearing on CNN Monday night, Hillary Clinton told Anderson Cooper she didn’t have her campaign tell the truth about her health issues because, “I just didn’t think it was going to be that big a deal.”

Cooper asked, “Why not just say on Friday, as you said apparently to Senator [Chuck] Schumer on Sunday, ‘I have pneumonia, folks, I’m gonna power through it.’ Why keep it a secret?”

“Well, I just didn’t think it was going to be that big of a deal,” she replied. “It’s the kind of thing that, if it happens to you, and you’re a busy, active person, you just keep moving forward.”

“But doesn’t your handling of this, and your campaign’s, their refusal to acknowledge what happened until really after that video was circulated confirm the suspicion of some voters that you’re not transparent or trustworthy?” Cooper asked.

“Oh my goodness, Anderson. You know, compare everything you know about me with my opponent,” Clinton replied. “I think it’s time he met the same level of disclosure that I have, for years.”
