He also famously attacked his political enemies over matters of their health and fitness, has lied consistently about verifiable and obvious health matters like his own weight and height, and famously passed off an unscheduled trip to the hospital as a 'routine physical' despite it not being on his schedule.

That's the ironic thing about a lot of your far right militia types; most of them are fat-bodies. Knowing about guns and how to shoot is great and all, but guess what?
