Obama Book Author: Hillary Clinton Needs to 'Get Back in Shape in More Ways Than One

New York Times bestselling author Ed Klein's doubled down in his criticism of Secretary of State Hillary Clinton's weight in an interview with The Blaze today. We caught up with Klein at a signing of his book "The Amateur," which is in its third week as No. 1 on the New York Times bestsellers list.

Last Monday Klein said on Fox News Radio he anticipated Clinton would run for president in 2016 but also said she's "not looking good these days" and that she's "looking overweight."

We asked Klein if that meant he thought Clinton was too fat to be president.

"I've gotten a lot of grief from women all over America for that statement, saying 'How dare you even mention the secretary of state's weight,'" he said. "But in fact if [New Jersey Gov.] Chris Christie were running for president I'm sure everybody would mention his weight. It's not a question of weight so much as it is she looks exhausted. She's had four very arduous years and looks as if she needs to recover and get back in shape in more ways than one. And she herself has said that she's tired."

That's true. Clinton has said she's exhausted -- over and over again.

"Of course she also said she's not interested in elective politics which I don't believe for two seconds," Klein continued, "but so what I was trying to get at is that in order to run for president, that's a four-year campaign and you need to be in shape for it and right now she's not but I think she can be-- get back into shape. So, I have to be very careful what I say about women's weight from now on."

In his interview with Fox Radio Klein suggested there might be something wrong with Clinton's health (other than being "overweight") that might inhibit her from running. "If her health holds out—that’s a big if, of course—if her health holds out, there’s no question in my mind she [will run]," he said at the time.

We asked if he knew about any specific health problems Clinton has.

"Well she has circulatory problems and she's had those for many, many, many years. Whether she has any other problems, I don't know," he said. "But she does not look very healthy right now. And you have to be in good health to run for president and she's going to be 69 years old... I thinks he's got a good chance. I think she's got the fire in her belly. And I think she's going to try to get herself back in good shape for it, but we'll see."
