From the September 12 edition of CNN Newsroom with Carol Costello:
CAROL COSTELLO (HOST): So, Donald Trump has been saying that Hillary Clinton lacks stamina, and maybe she's a little mentally unhinged. Could the type of pneumonia she has affect her stamina? Of course it could, right? But what about her mental capacity?
SANJAY GUPTA: I don't think there's any -- that we can draw any correlation between pneumonia and the mental capacity. It can make somebody tired and it can make somebody feel unwell clearly. I think that even what we saw on Sunday, if you take the pneumonia and also you add in other things like the medications that she's on for thyroid. She's upped her antihistamines which can be sedating. It could explain what you saw there. It was very noticeable, that what you saw getting into that van, it was very noticeable. But it could be explained by that. What is a little bit concerning, has nothing to do with the mentally unhinged comment but more to do with the fact that we still don't have all the information. We're still getting it very piecemeal here. Makes it hard to draw conclusions.
