Hillary Clinton canceled plans to visit California on Monday and Tuesday so that she can rest and recover at her home in Chappaqua, New York, following an incident on Sunday at the 15th anniversary ceremony for the September 11 attacks.

The 68-year-old Democratic candidate was diagnosed with pneumonia on Friday, her campaign said, after initially blaming her early departure from the memorial service and a stumble caught on video as she entered her SUV on becoming overheated.

Republican nominee Donald Trump and his campaign have repeatedly called Clinton’s health into question, declaring she “lacks the mental and physical stamina to take on ISIS and all of the many adversaries we face” in an August speech. Trump also tweeted that both candidates should release medical records to prove they were fit to serve as president.

While we await those details, take a look at what we already know about Clinton’s previous illnesses:

• December 2012: Clinton Suffers Concussion After Falling in Home

While Clinton was serving as secretary of state, she fainted at home and suffered a concussion as a result. The State Department released a statement at the time saying Clinton had been suffering from a stomach virus and became dehydrated when she lost consciousness.

“She has been recovering at home and will continue to be monitored regularly by her doctors,” the statement said. “At their recommendation, she will continue to work from home next week, staying in regular contact with Department and other officials.”

Following the concussion, Clinton wore glasses to help her with a double vision issue.

In July 2016, Clinton admitted to the FBI she did not remember all the briefings she received on handling sensitive information as she made the transition from her post as secretary of state due to the 2012 concussion.

January 2013: Clinton Goes to Hospital with Blood Clot

Clinton was admitted to a New York hospital at the start of 2013 due to a “potentially serious” blood clot that was discovered during a follow-up exam related to her previous concussion, the New York Times reported. She spent several days at New York Presbyterian Hospital being treated with blood thinners and proper hydration, according to the newspaper.

June 2014: Clinton Says She Has No Lingering Effects from Her Concussion

In an 2014 interview with PEOPLE, Clinton said she had no lingering effects from the concussion.

“I did have a concussion and some effects in the aftermath of it, mostly dizziness, double vision. Those all dissipated,” she said.

July 2015: Clinton’s Doctor Releases a Statement on Her’s Health

Clinton’s physician, Lisa Bardack, released a letter last summer declaring the Democratic nominee to be in “excellent physical condition.”

According to Dr. Bardack, Clinton was diagnosed with only hypothyroidism and seasonal pollen allergies.

The letter also addressed Clinton’s concussion and blood clot scare, but echoed her sentiments that all side effects disappeared within months of the accident.

September 2016: Clinton’s Coughing Fit Raises Eyebrows

While speaking at an event in Cleveland, Ohio, on Labor Day, Clinton suffered a coughing fit. Although she joked that her opponent was to blame – saying, “Every time I think about Trump, I get allergic” – #HackingHillary became a trending topic on Twitter as users speculated about Clinton’s well-being.

Trump took the opportunity to once again call Clinton’s health into question.

“Mainstream media never covered Hillary’s massive ‘hacking’ or coughing attack, yet it is #1 trending. What’s up?” he tweeted.

September 2016: Clinton Is Diagnosed with Pneumonia

After Clinton was forced to leave September 11 anniversary services early, she was caught on camera stumbling as she went to get into her SUV. Her campaign claimed she became overheated, and Clinton later told a crowd outside her daughter’s apartment that she felt “great.”

Later, it was revealed that she was suffering from pneumonia.

“Secretary Clinton has been experiencing a cough related to allergies,” Dr. Bardack said in the statement. “On Friday, during follow up evaluation of her prolonged cough, she was diagnosed with pneumonia. She was put on antibiotics, and advised to rest and modify her schedule.”

A source told PEOPLE that a bug has been going around Clinton’s campaign headquarters causing numerous staff members to fall ill.
