That's one reason why she limits press access. At any rate, my only point was that her health can become an issue without Trump saying "she has health issues." As you say, the question is self-evident, and Trump can put pressure on her with nothing more than "stamina." She makes relatively infrequent and short appearances. He, in contrast, gets by with little sleep, is healthy and physically active, campaigning his butt off. Stamina is a valued quality for a president.
Trump’s 16 hour days drive his staff crazy. LOL
