Democratic presidential candidate Kamala Harris has released a letter from her doctor declaring her in “excellent health” and fit for high office, aiming to contrast herself with her opponent, Donald Trump.

In a memo published on Saturday, Dr. Joshua Simmons reported that Harris’s April examination was “unremarkable.” He highlighted her active lifestyle, “very healthy diet,” manageable seasonal allergies, sporadic hives, and moderate alcohol consumption. “In summary, Vice President Harris remains in excellent health. She possesses the physical and mental resilience required to successfully execute the duties of the presidency, including those as chief executive, head of state, and commander in chief,” Simmons wrote.

At 59, Harris is running against 78-year-old Trump in the November election. With the race tightening, her campaign is leveraging the contrast of her relative youth and mental sharpness against Trump’s advanced age and occasional verbal missteps, hoping to persuade undecided voters that she is better suited for office.

Simmons noted that Harris’s allergies are well-managed through a combination of over-the-counter and prescription medications. Her sporadic hives, or urticaria, are not linked to specific triggers and respond well to antihistamines. For the past three years, Harris has been undergoing allergen immunotherapy, which has significantly improved her symptoms.

In the backdrop of this disclosure, Trump’s health has come under scrutiny. He previously raised concerns about President Biden’s health during the latter’s re-election campaign. Following Harris’s announcement, attention has shifted to Trump’s own health disclosures, especially as he has released very little information recently, including after a bullet grazed him during an assassination attempt in July.

While Trump released a letter from his physician last November claiming he was in “excellent” health, the letter lacked specific details such as weight, blood pressure, or cholesterol levels—information that is typically expected in such assessments. Harris’s move to share her medical report appears aimed at highlighting the transparency differences between the two candidates.
