Moore on Twitter also criticized the Democratic presidential nominee’s staff for not better aiding her when she nearly collapsed during a 9/11 memorial Sunday.

Moore additionally derided the Clinton campaign for keeping her illness secret, saying it provides ammunition for her critics.

Videos emerged Sunday showing Clinton wobbling as she left a 9/11 memorial ceremony early due to “overheating.”

Clinton’s doctor revealed later that evening the former first lady was diagnosed with pneumonia last Friday.

Dr. Lisa R. Bardack added that Clinton was “re-hydrated and recovering nicely” after the incident in New York.

Speculation over Clinton’s health has been fueled recently by a coughing fit she had in Cleveland last week.

Trump on Monday said he derives “no satisfaction” from Clinton’s health woes, adding she has struggled with health concerns before.

“It was quite sad, to be honest with you,” he told CNBC “Squawk Box” co-anchor Joe Kernen. "I hope she gets well soon. She was coughing very, very badly a week ago. This wasn’t the first time. I want her to get better, I want her to get out there. I look forward to seeing her in the debate.”

Bardack released a letter last July describing Clinton as “healthy,” noting her only medical conditions are hypothyroidism and seasonal pollen allergies. She also noted a concussion Clinton sustained in 2012.
