Vice President Kamala Harris plans to release a report Saturday on her medical history and health that a senior campaign aide said would show “she possesses the physical and mental resiliency” needed to serve as president.

Harris' advisers hope 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, the aide said.

Harris' office did not go into detail about how thorough the report on her medical history would be. The aide, who spoke on condition of anonymity to discuss a sensitive matter, said the report concludes Harris “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.”

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

Harris calls Trump 'incredibly irresponsible' for spreading misinformation about Helene response

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, who is 59, 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 like weight, blood pressure and cholesterol levels, or the results of any test.
