If he was relying on the same healthcare that veterans are typically entitled to then I very much doubt anyone here would object to it. In fact I think most on here would agree that all veterans deserve a higher standard of healthcare than they currently receive via their military service.
That isn't the issue though. The issue is the double standard that he represents due to the fact that he enjoys some of the best healthcare available in this country at the taxpayer's expense solely due to his current government position, while simultaneously using that government position to fight to remove access to a significantly lower standard of healthcare for tens of millions of other Americans.
