WASHINGTON — U.S. Vice President Kamala Harris is in “excellent health” and “possesses the physical and mental resiliency” required to serve as president, her doctor said in a letter released Saturday that summarizes her medical history and status. Dr. Joshua Simmons, a U.S. Army colonel and physician to the vice president, wrote that Harris, 59, maintains a healthy, active lifestyle and that her most recent physical, in April, was “unremarkable.” She “possesses the physical and mental resiliency required to successfully execute the duties of the Presidency, to include those as Chief Executive, Head of State and Commander in Chief,” he wrote in a two-page letter. Harris’ campaign hopes to use the moment to draw a contrast with Republican Donald Trump, who has released only limited information about his health over the years, and raise questions about his fitness to serve, according to a campaign aide who spoke on condition of anonymity to discuss sensitive matters. Trump has released very little health information, including after his ear was grazed by a bullet during an assassination attempt in July. Simmons, who said he has been Harris’ primary care physician for the past 3½ years, said the vice president has a history of allergies and urticaria, also known as hives, for which she has been on allergen immunotherapy for the past three years. Simmons said Harris’ latest blood work and other test results were “unremarkable.” Also in the report: Harris wears contact lenses for mild nearsightedness; her family history includes maternal colon cancer; she is up to date on preventive care recommendations, including having a colonoscopy and annual mammograms. As Harris’ office released the medical report, her campaign highlighted recent media reports raising questions about Trump’s health and mental acuity and his failure to provide information about health status and medical history. Trump, 78, eagerly questioned President Joe Biden’s health when the 81-year-old president was seeking reelection. Since Biden was replaced on the ticket with Harris, Trump’s own health has drawn more attention. Last November, Trump marked Biden’s birthday by releasing a letter from his physician that reported the former president was in “excellent” physical and mental health. The letter, posted on Trump’s social media platform, contained no details to support its claims — measures such as weight, blood pressure and cholesterol levels, or the results of any test.
