so people with chronic venous insufficiency, generally have congestive heart failure because what's happening is your heart's not able to pump out the blood as strongly as it should. So the Blood starts to back up and pools and where it pools is in the lowest part of your body because of gravity. And so that's your legs. And what happens is when your legs become swollen like that, your veins have valves that keep that from happening and the vows become leads to them. People get those really swollen legs. That's what's going on with Trump, probably.
