Fierce Trump haters as yourself don't realize he IS the POTUS, entitled to his opinions as you. Sorry.
BTW - he didn't arbitrarily come up with "heel spurs" as an excuse. He was medically disqualified by military medical examiners. You don't have an option to check an imaginary "choose your aliment for self disqualification" box. Not too familiar with U.S. military med protocol, I take it?
