After she won the title of Miss Universe 1996, Alicia Machado put on some weight. But she was horrified, she says, when Donald Trump, then an owner of the pageant, made her exercise at a gym in front of cameras.

Embarrassed, Machado, then 19, said Trump, who publicly criticized her weight gain -- he told Howard Stern she was an "eating machine" and said Machado had to keep thin as part of her responsibilities -- called her "Miss Piggy" and "Miss Housekeeping," which was apparently a reference to her accent and Venezuelan heritage.

I so proud and inspiration to be a U.S. Citizen! I'll be Voting! All my power and my support become with my next President @hillaryclinton Miss Housekeeping and miss Piggy Can Vote @realdonaldtrump A photo posted by Alicia Machado (@machadooficial) on Aug 19, 2016 at 8:54am PDT

Machado, now 39, says she suffered from eating disorders and depression after the Miss Universe episode. After becoming a United States citizen this week, Machado said she would be voting for Hillary Clinton and began stumping for the candidate in Florida.

The former Miss Universe shared an Instagram post from U.S. Citizenship and Immigration Services in Miami about her intention to vote for Clinton and tagged Trump, who is no longer an owner of the pageant.

"All my power and my support become with my next President @hillaryclinton," she said. "Miss Housekeeping and miss Piggy Can Vote @realdonaldtrump."

"Congratulations on becoming a U.S. citizen, Alicia," Clinton tweeted at Machado in May. "Enjoy casting that vote."
