Ok, he spent 5 minutes writing the note. So what? What is important is how long he spent examining Trump & how thorough was the exam.
The length of time spent on the memo & the extent of the exam are not necessarily correlated.
However, it doesn’t sound like this guy is too credible. On the other hand, Hillary’s note/letter was a 1-page summary also - so not too insightful.
He’s a board certified Internist and Gastroenterologist. He went to Tufts University. He’s rated 4.5 stars by patients. Sounds like a Dr. I would want.
