 How tall is Trump? 6'3". He's 6'3". I don't care if you're a male or female Secret Service agent. When you're on close detail, as these people were and are at every single appearance that Donald Trump makes, it makes no sense whatsoever to have somebody, male or female, who is 5'8", or 5'6", guarding him. Because, gee, that leaves a lot of body exposed, even if you put yourself between him and the bullet.
