The video comes from the Latino Activist Group "Deport Racism" and it's reached almost half a million views on YouTube.
Los Angeles film director Luke Montgomery says he produced the attack on Trump for the group.
"Ola Donald Trump, screaming 'get out of my country' you Republicans use offensive words, so here are a few of our own (expletive) you, racist (expletive)," said a child on the video.
Some views may think the video is over the top, but that was by design says Luke Montgomery. He says he had to get Donald Trump's attention and he did.
Trump appeared on the FOX Business Channel Friday.
"I mean to have young kids use that kind of language is a disgrace, and it totally backfired, people are going wild about it, anybody who would do an ad like that is stupid," said Donald Trump.
"I am Ricardo; my friends call me Rick, but you can call me anchor baby, racist (expletive)."
So could it undercut the success of his message by having children using f-bombs?
"No, absolutely not, everybody has heard these words before. We think Donald Trump's language, calling Mexicans rapists, murderers, drug dealers are the real offensive videos, so if he doesn't like our video, we think that's wonderful," said Montgomery.
Trump is set to host Saturday Night Live this weekend. Deport Racism is offering $5,000 to anyone on the set or in the studio audience who yells out, or gets on camera during the live TV broadcast and is heard clearly saying "Deport Racism" or "Trump is a Racist."
