Doctor: Hillary Clinton 'healthy and fit to serve as president'

The letter, which will detail the treatment she received in the days before and after her Friday pneumonia diagnosis, including a chest scan, says she was given a 10-day course of antibiotics to treat the condition.

Clinton has been evaluated several times by her physician, Dr. Lisa Bardack.

"The remainder of her complete physical exam was normal and she is in excellent mental condition," Bardack's letter will state.

Additional health records released with the letter will show that Clinton's cholesterol and blood pressure are within normal ranges.
