Democratic presidential candidate Hillary Clinton has gone missing from her campaign trail amid growing suspicion among her critics that she has been lying about the state of her health.

One such critic, Senator Rand Paul (R-Kentucky), told Breitbart that she’s suffering from “significant health problems,” although he admitted that he has no idea what those would be.

“Her losing consciousness, there, which by all appearances she did lose consciousness, is not something commonly associated with pneumonia,” Paul, a licensed eye surgeon, said.

There has a been a slew of conspiracy theories about Hillary Clinton’s supposed health issues. The allegations range from Parkinson’s, dementia, and dysphasia. Her physician, Dr. Lisa Bardack, has previously proclaimed the presidential candidate fit to run for the presidency.

However, the doctor reported that the former First Lady also has hypothyroidism, some seasonal allergies, and some blood clots. A medical report dating from July 28, 2015, indicated that she was taking antihistamines, Coumadin, Armour Thyroid, and Vitamin B-12.

The Daily Caller has noted that Hillary Clinton has been missing from the campaign trail ever since she complained of nausea and fainting spells during the Sept. 11 Ground Zero ceremony in New York City.

The presidential nominee has scheduled five political rallies this month, but there’s no word on when she will rejoin her team on the road. Right now, she’s relying on her team—as well as husband Bill Clinton—to do the heavy lifting.

Those present at the political rallies on her behalf include running mate Virginia Senator Tim Kaine and his wife, Anne Holton; daughter Chelsea Clinton; Vice President Joe Biden; First Lady Michelle Obama; and Vermont Senator Bernie Sanders.

But Hillary Clinton already missed some events in September, including a massive rally in Las Vegas, although Bill Clinton hosted the event in her place. She missed another fundraiser in North Carolina, although the reason why was not specified.

Breitbart said the event in Chapel Hill, North Carolina, was huge, considering that the opportunity to have lunch with Hillary Clinton can cost each participant somewhere between $2,700 to $100,000.

Between today and Oct. 19, Hillary Clinton is not expected to host a rally, although she will be at one fundraiser set in Washington D.C. along with Chelsea Clinton, the vice president, and the First Lady.

Following her fainting spells during the 9/11 ceremony, her campaign team released a statement explaining the episode to bouts of pneumonia.

Bill Clinton said in an interview with CBS on Sept. 12, 2016, that his wife has the tendency to overwork herself, and her fainting spells were caused by dehydration. Other than that, “she’s doing fine.”

But Rand Paul said that the explanation about Hillary Clinton’s episode with pneumonia was confusing.

“The diagnosis as a something being a non-infectious infection is kind of a strange way to describe pneumonia as well,” he said. “Her health is an issue. Particularly the fact that she has not been very forthcoming with it.”

Hillary Clinton’s health notwithstanding, Paul said that the presidential nominee is not fit to run the country more so because of her past decision that cost American lives.

Americans by now knows the story about the attack on the Libyan compound in Benghazi on Sept. 11, 2012, by Islamic militants. When the smoke cleared, four Americans lay dead including US Ambassador J. Christopher Stevens, CIA contractors Tyrone S. Woods and Glen Doherty and US Foreign Service Information Management Officer Sean Smith.

Hillary Clinton was the State Secretary at that time.

“My advice–although it has not been requested–is to make the point that she is not fit to be commander-in-chief because she pulled the security out of Benghazi,” the senator said, adding that she’s not as brilliant in foreign affairs considering that she “has been wrong ‘in Iraq, Libya and Syria.'”
