WHITE PLAINS, N.Y. — Hillary Clinton on Thursday told reporters she was "doing great" as she returned to the campaign trail after recovering from pneumonia that sidelined her for three days.
Meantime, Donald Trump's campaign issued health information with his doctor proclaiming him in "excellent physical health."
The Democratic presidential nominee spoke briefly on her campaign plane. She did not take detailed questions, though was expected to do so later in the day.
Clinton hadn't campaigned since she became dizzy and dehydrated during a 9/11 memorial service in New York on Sunday. Her campaign later said Clinton had been diagnosed with pneumonia on Friday. The campaign's handling of her illness has contributed to the public's lack of trust in the former secretary of state and a presidential race that is tighter than many expected.
Earlier, she told the Tom Joyner Morning Show: "I'm really glad that I did finally follow my doctor's orders and take some days to rest instead of just trying to keep powering through, which I think is a common experience for people."
Clinton and Trump both released letters from their doctors this week with additional details about their health, including cholesterol levels, blood pressure and current medications. Both candidates' physicians declared them fit to serve as president.
In releasing a letter from Trump's doctor Thursday, Trump's team appeared to take a swipe at Clinton's brief absence from the campaign trail. The Clinton campaign's handling of her pneumonia diagnosis has contributed to the public's lack of trust in the former secretary of state and a race that is tighter than many expected.
"We are pleased to disclose all of the test results which show that Mr. Trump is in excellent health, and has the stamina to endure — uninterrupted — the rigors of a punishing and unprecedented presidential campaign and, more importantly, the singularly demanding job of president of the United States," the campaign said in statement.
Trump first provided a summary of a recent physical to Dr. Mehmet Oz while taping an episode of Oz's TV show. He said on the show that he gets exercise during the campaign by delivering speeches at rallies, calling them "a lot of work" and requiring "a lot of motion."
Trump's doctor, Harold Bornstein, says the Republican is 6-foot-3 and 236 pounds — giving him a body mass index falling into the "overweight" range.
The 70-year-old has blood pressure of 116 over 70, blood sugar level of 99 and a calcium score of 98 as of 2013, which was also the year of his last colonoscopy, the doctor wrote. The note put his cholesterol level in normal range, with HDL cholesterol at 63, LDL at 94 and triglycerides at 61. He has a calcium score of 98 as of 2013, which was also the year of his last colonoscopy, the doctor wrote.
The report noted that Trump was hospitalized only once as a child, at age 11.
His last transthoracic echocardiogram was in December 2014. He had a normal EKG and chest X-ray on April 14 of this year. He takes a low dose of aspirin and a statin, rosuvastatin, also known as Crestor, that lowers cholesterol.
The note from the campaign said that Trump was examined Sept. 9 by Bornstein, who wrote that the candidate is examined annually every spring.
Bornstein declared Trump in "excellent physical health" and noted that his parents, Mary and Fred, lived into their 80s and 90s. The doctor did not note that the elder Trump had Alzheimer's disease.
The press release accompanying the doctor's note made mention of the candidate "setting records for number of events, size of crowds, and breadth of travel on the campaign trail."
Until now, the main source of information about Trump's health has been a widely mocked letter from his longtime physician declaring he would be the healthiest president in history.
Clinton running mate Tim Kaine also released a letter from his doctor, Brian Monahan, the attending physician of Congress. The letter says Kaine is in "overall excellent health," has never smoked and has "modest" alcohol use.
Trump's running mate Mike Pence said he plans to release records from a recent physical examination Thursday.
Clinton was campaigning Thursday in Greensboro, N.C., and speaking to a Hispanic group in Washington. Those are her first public appearance since Sunday, when she abruptly left the 9/11 memorial service.
Jennifer Palmieri, Clinton's communications director, said the candidate's break from the campaign trail helped her "sharpen the final argument she will present to voters in these closing weeks." Clinton's remarks Thursday were to focus on lifting up children and families, as the campaign tries to break through with a more positive message.
Clinton released information from her doctor more than a year ago and provided updated information Wednesday following her pneumonia diagnosis.
The new letter from Clinton's doctor stated that a chest scan revealed she had "mild, non-contagious bacterial pneumonia." Dr. Lisa Bardack, chair of internal medicine at CareMount Medical in Mount Kisco, N.Y., said Clinton was treated with a 10-day course of Levaquin, an antibiotic used to treat infections.
"She is recovering well with antibiotics and rest," wrote Bardack, who also authored the letter about Clinton's health released in July 2015. "She continues to remain healthy and fit to serve as president of the United States."
Clinton, 68, has blood pressure of 100 over 70. Her total cholesterol was 189; her LDL or "bad" cholesterol was 103, and her HDL or "good" cholesterol was 56 — all within healthy levels and not signaling the need for any medication. She has also had a normal mammogram and breast ultrasound, according to the letter.
The letter from Clinton's doctor made no mention of her weight, a key part of any medical exam, nor did a similar letter released last year.
