Referring to a statement by Bill Clinton, who claimed it wasn’t the first such “medical episode” to hit Clinton, Anderson Cooper said, “Can you say how many times over the course of say the last five years you’ve been dehydrated and gotten dizzy? I know you passed out, hit your head in 2012 that led to the concussion.

“How often has this happened?” Cooper asked.

“Oh, I really only twice,” Clinton replied, “uh, that I can recall.

“You know, it is something that has occurred a few times over the course of my life and, you know, I’m aware of it, and usually can avoid it,” she said.

She said the episode yesterday was the result of being “incredibly committed” to being at the 9/11 remembrance memorial.

“I did feel how hot and humid it was. I felt overheated and that I did need to leave.”

She said after she got into the air-conditioned van she felt better.

The Washington Examiner reported yesterday that the temperature was “just 75-77 degrees, one of the coolest in the past month.”

The site continued, “Weather Underground said it was 75 degrees at the time, a day after it reached 94 when it was also extremely muggy in downtown New York City.

“Sunday, however, was much cooler and breezy with little of the humidity of the whole summer.”
