AN ex-secret serviceman who worked for Hillary Clinton has questioned whether the presidential candidate really fainted on Sunday and claimed she may have suffered a seizure.

Gary Byrne, who wrote a tell-all book on the Clintons titled Crisis of Character, spoke to The Mirror Online about the Democratic nominee’s medical episode at a 9/11 memorial service last weekend.

The former agent, who spent 29 years in the secret service, said that “people need to know the truth” after Hillary’s team said the 68-year-old had been diagnosed with pneumonia.

After analysing the footage showing Clinton being helped into a car after appearing to collapse, Byrne said she displayed symptoms of a seizure.

He said: "Her posture is very rigid - she's almost back on her heels and if you watch her, her head actually lifts up and you can see this rigid posture.

"Clearly the two staff members - one standing behind the other - the front one is clearly still controlling Mrs Clinton.

"The shift leader, the bald guy, walks right in front of Mrs Clinton.

"Now typically the shift leader or agent would never walk in front of the protectee as they're getting into a vehicle, because you're blocking their path.

"But the reason he is doing it is because he knows she can't move under her own power.

"He's going to come around and he's going to take her right arm - and watch what happens to Mrs Clinton.

"It's sad to watch but she starts to fall and of course they catch her."

And while Byrne insists he is not a medical professional, he believes that the former First Lady’s medical episode was more serious than was officially reported.

He said: "I've seen quite a few seizures unfortunately in my time - she was panting out and her body completely collapses.

"Now I'm not a doctor, but what I see there is Mrs Clinton completely rigid as if she was having a seizure." ,

In Byrne’s professional opinion, the behaviour of the agents protecting the White House hopeful indicate that they wanted to get her medical attention as quickly as possible.

He said: "The fact that they're waiting out in the open like that where her only protection are her against waiting on the vehicle - that's a significant thing too.

“They wouldn't normally do that.

"And they're doing it because they want to get out of the public eye and they want to get her medical treatment."

Instead of being taken to hospital, Clinton was rushed to her daughter Chelsea’s New York apartment

And former agent Byrne believes this was to enable the former Secretary of State to receive private medical treatment from her own doctors.
