Hillary Clinton’s personal doctor on Sunday said the Democratic presidential candidate was suffering from pneumonia after she fell ill at a Sept. 11 memorial, in an episode that renewed focus on her health less than two months before the general election.
Clinton was diagnosed on Friday, but her condition only came to light several hours after a video on social media appeared to show her swaying and her knees buckling before she is helped into a motorcade as she left the memorial early Sunday.
Clinton had a medical examination when she got back to her home in Chappaqua, New York, according to a campaign aide. Her doctor, Lisa Bardack, said in a statement that she has been experiencing a cough related to allergies and that an examination on Friday showed it was pneumonia.
“She was put on antibiotics and advised to rest and modify her schedule. While at this morning’s event, she became overheated and dehydrated. I have just examined her and she is now re-hydrated and recovering nicely,” Bardack said.
It was not yet clear whether Clinton would stick to a hectic schedule that has her travelling to California on Monday for several campaign and fundraising events.
Regardless of how much the illness curtails the 68-year-old’s campaigning, the diagnosis comes at a crucial time in the White House race against Republican rival Donald Trump. The first of three debates is on Sept. 26 and the election is on Nov. 8.
Some Clinton allies said the incident underscored the candidate’s resilience.
“After being diagnosed with pneumonia, Hillary Clinton ran a two-hour national security meeting, gave a press conference, and spent an hour and a half in the heat at a September 11 event,” said Peter Daou, who worked for Clinton in the past and now has a communications firm.
“It was an impressive feat of physical strength that undermined weeks of health conspiracies.”
Clinton abruptly departed the high-profile, televised event at Ground Zero and was taken to her daughter Chelsea’s home in Manhattan. She emerged around two hours later on a warm and muggy morning, wearing sunglasses and telling reporters that she was “feeling great.”
The video that showed her swaying and buckling with aides holding her up came from an unverified Twitter account under the name Zdenek Gazda, who did not respond to a request for comment. The Clinton campaign did not respond to repeated requests for comment about the authenticity of the video.
As the solemn ceremony began at the site of the World Trade Center that was attacked by two hijacked airliners 15 years ago, there was patchy sunlight, with temperatures at about 80 degrees Fahrenheit (26.6 Celsius). But the high humidity early into the ceremony caused it to feel much hotter in the crowd at times.
Clinton wore a high-collared shirt and a dark pant suit and donned sunglasses for the morning event. Democratic Representative Joe Crowley of New York, a Clinton supporter who attended the event, told Reuters that it was “incredibly, stiflingly hot” during the ceremony.
Clinton’s pneumonia diagnosis follows a wave of conservative conspiracy theories that circulated in recent weeks suggesting that Clinton’s coughing was a sign of deeper problems.
Clinton’s speech at a campaign rally earlier this month in Cleveland was interrupted by a coughing spell. During the speech, she quipped, “Every time I think about Trump I get allergic.” She then resumed her speech.
In a letter released by her doctor in July 2015, Clinton was described as being in “excellent health” and “fit to serve” in the White House. It noted that her current medical conditions include hyperthyroidism and seasonal pollen allergies.
