Multimillionaire White House hopeful Mitt Romney owes rival Rick Perry some money, according to Jon Huntsman.

Romney offered Perry a $10,000 bet during the Iowa Republican debate on Saturday over whether he said in his book that the health insurance mandate he signed into law as the governor of Massachusetts should be the model for the country.

Perry declined to take the bet, but Huntsman jumped on it.

Huntsman was not invited to the debate, but his campaign released a YouTube video on Saturday night titled "Challenge Accepted." The video shows clips of Romney saying his health insurance mandate was a good model for the entire nation. In one clip, Romney states, "I like mandates."

Huntsman's campaign has also launched the website, which displays news reports about the bet.
