Mexico’s former president had some words for The Donald. And not very nice words either.

Fox claims Trump owes American workers an apology for, “all the imports from China and Mexico.” “Please apologize to them,” Fox implored.

The cornerstone of Trump’s campaign is his claim that he’ll build a big beautiful wall along the U.S. southern border with Mexico and require the Mexicans foot the bill. Months ago, Fox said Mexico certainly would not pay for the “f*cking wall.”

Tuesday, Fox doubled down on the sentiment and called Trump a false prophet.

NBC News reports:

“I’m not going to pay for the f**king wall,” Fox said. “And please don’t take out the f**king full word.”

“Wake up Americans,” Fox warned. “He is a false prophet.”

“Think about it, analyze what he’s proposing,” Fox continued. “Count the amount of lies he says in every speech, everyday he lies and lies with figures because his sole interest is to do personal business.”

“He is the hated gringo because he is attacking all of us,” Fox said. “He is offending all of us. Imagine, that could take us to a war — not to a trade war.”

Before his expletive-filled rant regarding Trump, Fox and Mathis discussed the North American Free Trade Agreement (NAFTA), which has been a highly contested topic in the 2016 presidential election. Fox said corporations like Chrysler, Ford Motor Company and General Motors survived the bailout thanks to the trade agreement because it used taxpayer bailout money to become competitive again in all three North American countries.

“The partnership deal of NAFTA nourishes the competitiveness of the three economies of Mexico, US and Canada,” Fox said. “… The U.S. cannot compete by itself against others. If Trump says, ‘let’s enclose by ourselves, let’s build walls and then impose heavy taxation to imports,’ he’s going to asfixiar (asphyxiate) the U.S. economy.”
