For 20 years, Alicia Machado has lived with the agony of what Donald J. Trump did to her after she won the Miss Universe title: shame her, over and over, for gaining weight.
Private scolding was apparently insufficient. Mr. Trump, who was an executive producer of the pageant, insisted on accompanying Ms. Machado, then a teenager, to a gym, where dozens of reporters and cameramen watched as she exercised.
Mr. Trump, in his trademark suit and tie, posed for photographs beside her as she burned calories in front of members of the news media. This is somebody who likes to eat, Mr. Trump said from inside the gym.
On Monday night, Hillary Clinton turned Ms. Machados pain into a potent political weapon on the biggest stage.
In the process, Ms. Clinton, the first female presidential nominee of a major party, elevated a largely forgotten tale of Mr. Trump, when his oversight of beauty pageants collided with his unforgiving fixation with female beauty.
