A coalition of Latino conservative groups and activists delivered a stern message to the Republican candidates running in the 2016 presidential race, to not engage in inflammatory anti-immigration rhetoric or else they will risk losing their support in the general election.

Two dozen top Latino conservative groups issued the warning to the GOP candidates on Tuesday, just one day before the third Republican presidential debate, which will take place Wednesday evening in Colorado.

The meeting, which was held at a hotel located just a mile away from the televised Republican debate, was organized by the American Principles Project's Latino Partnership and included small business owners, working moms and veterans.

"We want candidates to know: We're monitoring your language. We are monitoring what you propose. And we're going to hold you accountable," said Alfonso Aguilar, head of the American Principles Project's Latino Partnership.

While speaking to reporters, the Latino leaders also blasted Donald Trump -- who has infamously called Mexican immigrants rapists and drug dealers -- as an unelectable candidate who cannot win over the Hispanic voters needed to win in swing states.

"This group unanimously has decided that Donald Trump is not a candidate who we can support," said Jerry Natividad, one of the organizers of the meeting, reports Time.

Although she didn't mention Trump by name, Rosario Marin, former U.S. treasurer of the under President George W. Bush, also delivered a fierce warning to the billionaire businessman.

"Foolishly, some candidates don't think they need the Hispanic vote in the primary. Heed our warning. Don't expect us to come to your side during the general election. You are not with us now, we will not be with you then. You don't need our vote now, you won't have it then. You insult us now, we will be deaf to you then. You take us for granted now, we will not recognize you then," she said, according to NBC News.

"We have not worked on behalf of this party for decades only to see our community work undone by the divisiveness of some candidates. I will not name names, but one in particular has earned my absolute disgust and contempt. I will not dirty my mouth by pronouncing his name. In fact, grouping him as a candidate is an insult to the serious candidates we have in this primary," she added.

Aguilar added that the coalition will begin targeting other candidates should they utter xenophobic comments.

"It's a shot across the bow to candidates who embrace Trump and who embrace those proposals that you should be worried, because we're going to call you out," he said. "This is how you build political leverage, so we can have an exchange. So if they want to talk to us, great, but at the end we want change, and if we don't see it, they will hear from us."
