WASHINGTON (AP) — Vice President Kamala Harris is in “excellent health” and “possesses the physical and mental stamina” required to serve as president, her doctor said in a letter A report summarizing her medical history and health status was released on Saturday.

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 last physical exam last April was “unremarkable.”

She “possesses the physical and mental resilience necessary to successfully discharge the duties of the presidency, including those as head of government, head of state and commander in chief,” he wrote in a two-page letter.

Harris’ aides hope to use the moment to draw a contrast Republican Donald Trumpwho has released limited information about his health over the years, raising questions about his fitness to serve, according to a campaign aide who spoke on condition of anonymity to discuss sensitive topics.

Trump has released very little health information, including after his ear was grazed by a bullet in an assassination attempt in July.

Trump, 78, questioned eagerly President Joe Biden Health as the 81-year-old president sought re-election. Since Biden was replaced on the ticket by Harris, 59, Trump’s own health has drawn more attention.

Last November, Trump celebrated Biden’s birthday by issuing a letter from his doctor, who reported that the former president was in “excellent” physical and mental condition.

The letter posted on Trump’s social media platform did not contain any details to support its claims – measurements such as weight, blood pressure and cholesterol levels, or the results of a test.
