Another former president of Mexico blasted GOP candidate Donald Trump's idea to build a border wall, using colorful language.
"I declare, I'm not gonna pay for that f*****g wall," ex-president Vicente Fox told Univision's anchor Jorge Ramos, in a video clip posted on Twitter Thursday. "He should pay for it; he's got the money."
The billionaire real estate mogul has made immigration one of the centerpieces of his campaign, saying on the day he announced his candidacy that Mexico was sending "rapists" and "criminals" across the border.
Former Mexican president Felipe Calderón also had harsh words for Trump earlier in February: "We are not going to pay any single cent for such a stupid wall! And it's going to be completely useless."
During his conversation with CNBC's Hadley Gamble, Calderon said it was "incredible" that quite an "admirable society" like the United States had candidates like Trump.
Trump reacted with outrage on Twitter Thursday afternoon, saying Fox "horribly used the F word" and "must apologize."
"If I did that there would be a uproar!" Trump tweeted. His campaign did not respond to a request for comment.

Asked if he's "afraid" Trump will be America's next president, Fox, who led Mexico from 2000 to 2006, said: "Not at all, democracy cannot take us to crazy people that doesn't [sic] know what's going on in the world today."
But Fox admitted he was troubled by Trump's latest decisive victory over his rivals at the Nevada caucus on Tuesday.
Fox said the Hispanics who voted for Trump are "followers of a false prophet."
He said Trump is "going to take them to the desert. And if they think they will benefit with an administration led by Donald Trump, they're wrong. They must open their eyes."
Fox said the United States "will fail if it goes to the hands of a crazy guy" and added that Trump doesn't represent Republican principles.
