Donald Trump on Friday blasted a video from a Hispanic advocacy group, in which children derided the Republican presidential candidate's views on immigration using swearwords and other coarse language. The candidate called the clip a "disgrace" and its makers "stupid."

"I think it's terrible, I think it's just terrible," Trump said on Fox Business Network's "Mornings with Maria Bartiromo," according to Politico. "Anybody that would do an ad like that is stupid, to be honest. I mean, they're stupid people that would do an ad like that."

The ad, released earlier this week by the Deport Racism political action committee, featured a child identified as Ricardo referring to Trump with an expletive and calling him a "racist." It received strong criticism, not only from the former "Apprentice" star, but also from some of his challengers in the race for the Republican nomination, The Hill noted.

Marco Rubio, one of the two Hispanic candidates in the crowded GOP field, for instance, called the video "disgusting," according to the Washington publication.

"What kind of parent lets their children go on a video like that and use that kind of profanity?" the Florida senator wondered on Fox News' "Fox & Friends." "They're not bringing people to their side -- they're turning people off. People look at that and say, 'These people are grotesque.'"

But Luke Montgomery, the director of the spot, said that the parents did, in fact, know what their children were doing and were not opposed to their appearance in the video. In the clip, the children also beat a pinata version of Trump, and accused him of hating the Constitution's protection of all Americans and of wanting to "tear [up] the Bill of Rights," the Washington Examiner detailed.

"Calling Mexican immigrants 'rapists,' 'murderers,' and 'drug dealers?' Calling kids, American citizens, 'anchor babies?' That's diminishing their rights as Americans," Montgomery told Politico in reference to some of Trump's controversial statements. "You can only get away with that if you think they're second class because they're brown. I think they're using a bad word for a good cause."
