I don't think that's true actually.
I think he lied about his height because he's literally so pathetic he attributes height to power. The listed 6'3'' height is definitely something I saw before this medical report.
However i'm sure they took a lot of weight off.
So his personal physician listed him as 6"3, the Presidential physician listed him as 6"3, and he himself claims he's 6"3 but this is actually a lie somehow?
Because what? Because you just think these massively overqualified physicians can't use a tape measure or are somehow lying?
Maybe you should have read to this paragraph:
A correction issued by the New York Times in September 2016, ahead of Trump's election, stated that a story "misstated the candidate’s height, as reported in a recent letter from his physician. Mr. Trump is 6-foot-3, not 6-foot-2." The story was written by Dr. Lawrence Altman, who has for decades written about the health of presidents and presidential candidates.
The White House and reporters who cover Trump have said that Fire and Fury contains many inaccuracies.
