Former Mexican President Vicente Fox blasted U.S. President Donald Trump's border wall on Aug. 4, using the f-word as he did so (video below).
CNN was interviewing the former Mexican leader, who served as president from 2000-2006, via Skype when he passionately spoke out against Trump's proposed wall.
"Well, you can use my words: We’ll never pay for that f**king wall," he said on live television. "For that whole wall. That makes it more clear."
Fox also responded with a "yes" after he was asked if current Mexican President Enrique Pena Nieto should have been more assertive in talking to Trump in January.
"Why should Mexico pay for the wall?" Fox said. "What’s the reason? We don’t need a wall. If Trump wants to build a wall, he has to go to Congress and he has to tell the truth to U.S. taxpayers that they’re going to pay for that."
Fox also criticized Trump's request to Pena Nieto that he refrain from speaking negatively about the wall in public.
"What Trump is trying to do is save face in front of his voters," said Fox. "He’s not looking after America. It’s just him trying to save face."
Many praised Fox's stance.
"Vicente Fox is awesome," wrote one person on the New York Daily News' Facebook page.
"It was called for," wrote one reader of The Hill, referring to Fox's f-bomb. "Mexico paying for the wall because Trump says so is a ridiculous premise. Its obvious that Trump thought he was getting the powers that one would associate with a dictatorship when he 'won' the presidency...and ever since then, he has been learning (slowly) that when he is opposed by many (as he currently is), he has very little power to do anything."
Others criticized Fox.
"Hey Vincente, how many millions of dollars in bribes did your family receive from Mexican drug trafficking cartels?" wrote one person.
"Vicente Fox has no issue with his Mexican citizens in Mexico paying with their blood and lives over the drug cartel war," added another. "Yet, he is ready to chime in on American policy. Go figure. Vicente go clean your mustache from the caviar and tequila."
Fox isn't the only world leader making headlines for blasting Trump recently. Only two days before Fox's interview, former Scottish leader Alex Salmond called Trump "a complete and utter nincompoop," reports The Hill.
Salmond was angry at comments the U.S. president made opposing Scotland's independence.
"The Grand Canyon is a minor crevice compared to the vast chasm of ignorance of that man," he said of Trump.
