In a Feb. 25 interview with Jorge Ramos on Fusion, Fox responded to Trump's plan to build a wall between Mexico and the United States and get Mexico to pay for it.
"I'm not going to pay for that f---ing wall. He should pay for it. He's got the money," Fox said. "What is Trump? He's not a Republican. Absolutely not. Those are not the Republican principles. He's not a Democrat. He is just himself. He is egocentric."
Fox decried Trump's visit to Mexico in an interview with CNN this morning just hours before Trump's scheduled meeting with Pena Nieto.
"Trump is using Mexico, is using President Pena to push his sinking poll numbers," Fox said on CNN's "New Day." "So it's a very opportunistic move, and I hope U.S. public opinion, U.S. citizens can see this and finally, and finally see what is behind Trump, this false prophet that is just cheating everybody."
Pena Nieto has also said his country would not pay for a wall. In an interview published in the Excelsior newspaper on March 7, he likened Trump's "strident" rhetoric to that of dictators like Benito Mussolini and Adolf Hitler.
"There is no scenario," Pena Nieto said when asked by Excelsior whether there were any circumstances under which Mexico would pay for the proposed wall. "Of course I can't agree with this American politician's position."
Pena Nieto continued by attacking the tone of Trump's campaign. "And there have been episodes in human history, unfortunately, where these expressions of this strident rhetoric have only led to very ominous situations in the history of humanity," he told the newspaper. "That's how Mussolini got in. That's how Hitler got in. They took advantage of a situation, a problem, perhaps, that humanity was going through at the time, after an economic crisis."
Ramos said on CNN Tuesday night that the meeting with Pena Nieto could be a sign that Trump is "in panic mode when it comes to Latinos." Trump once had Ramos, a Mexican-American journalist, removed from a campaign news conference in Iowa for asking questions about the candidate's proposed immigration policies.
"It doesn't matter what he says tomorrow. He already lost the Latino vote," Ramos told CNN.
