White House physician Dr. Ronny Jackson said that United States President Donald Trump overall health 'is excellent' and he did 'exceedingly well' on cognitive screening. Trump had a normal score on a cognitive exam and is in excellent health, although he could benefit from a lower-fat diet and more exercise, Jackson added. The U.S President had performed well on a cognitive assessment, which the president had requested, said Jackson. A journalist wrote in a book that the mental heath of the US President is not sound, post which White House released this statement.
