It’s a September swoon. After abruptly leaving a 9/11 memorial in New York yesterday, Hillary Clinton revealed she is suffering from pneumonia diagnosed on Friday — raising questions about her physical fitness and transparency. Coming just after she dismissed half of Donald Trump’s backers as a “basket of deplorables,” it’s a shaky moment for a campaign seeing its lead shrink. Trump has eagerly pressed health concerns in recent months, and has now said he’ll release his own elusive medical records for comparison. Clinton has canceled Monday and Tuesday West Coast campaign stops while she recovers.
