The issue was brought up by Hillary Clinton, the Democratic presidential nominee, during Monday's televised debate with Mr Trump. She was making a point about her rival's remarks about women.
"This is a man who has called women pigs, slobs and dogs and someone who has said pregnancy is an inconvenience to employers, who has said that women don't deserve equal pay unless they do as good a job as men.
"And one of the worst things he said was about a woman in a beauty contest. He loves beauty contests, supporting them and hanging around them.
"And he called this woman 'Miss Piggy.' Then he called her 'Miss Housekeeping,' because she was Latina. Donald, she has a name. Her name is Alicia Machado.
"And she has become a US citizen and you can bet she is going to vote this November."
