HEMPSTEAD, N.Y.-- The former Miss Universe winner who was harshly criticized by Donald Trump as "fat" is the subject of a new, brutal web video by the Clinton campaign highlighting his treatment of her after the pageant.

Venezuela's Alicia Machado was the first Miss Universe winner after Trump bought the pageant franchise but later became the subject of Trump's withering ridicule.

In the video, Machado recounts in Spanish what she said was Trump's public humiliation of her after she gained weight.

"It had turned into a circus, the joke of 'The fat Miss Universe,'" Machado said. "A joke that caused me a lot of pain."

In the video, Trump is shown bringing television cameras to Machado's workout and telling the cameras, "She weighed 118 or 117 pounds and she went up to 160 or 170."

"So this is somebody that likes to eat," he added.

Machado said that afterward, she suffered eating disorders. And Trump, who was required to pay her for the commercial work she did after the pageant, didn't pay her and threatened to take away her crown, she said.

The video comes a day after Machado's story was featured on the presidential debate stage on Monday night at Hofstra University, when Clinton confronted Trump about it.

"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," Clinton said.

Trump countered by repeatedly asking Clinton, "Where did you find this?"

On Tuesday morning, Trump repeatedly attacked Machado in an interview on Fox News.

"She was the worst we ever had. The worst. The absolute worst. She was impossible," Trump said. " ... She was the winner, and she gained a massive amount of weight, and it was a real problem. We had a real problem."

On the debate stage, Clinton noted that Machado is now a U.S. citizen and plans to vote against Trump in November.
