The letter from Trump's long-time doctor, Harold N. Bornstein, lists Trump's weight, cholesterol, blood pressure, blood sugar and other numbers.
He concludes that Trump "Is in excellent physical health."
The letter, released Thursday, is more detailed than one he had released previously that consisted largely of platitudes.

The release comes amid growing attention to the candidates' health histories and after Clinton was captured on video stumbling.
Trump's campaign appeared to refer to that episode when it said Trump "has the stamina to endure - uninterrupted - the rigors" of the campaign and presidency.
