At almost all of his campaign rallies, Donald J. Trump leads a familiar refrain as he details his plan to build a giant wall along the border with Mexico.
"Who's gonna pay?" he asks.
Without fail, his adoring fans reply, "Mexico!"
While the Mexican government has said little about Trump's plan to beef up border security, two of the country's former presidents have a message for Trump: Mexico won't pay.
"I'm not going to pay," Vicente Fox said, using a profanity to comment about the wall Thursday in an interview with Fusion. "He should pay for it. He's got the money."
Fox, who was president of Mexico from 2000 to 2006, called Trump "egocentric" and lacking in any political values. He also expressed disbelief that Trump had done well with Hispanic voters in the Nevada caucuses on Tuesday and called on them to open their eyes.
"I'd like to know who those Hispanics are," Fox said. "They are followers of a false prophet."
Fox's successor, Felipe Calderón, expressed similar concerns about the wall this month.
"Mexican people, we are not going to pay any single cent for such a stupid wall!" Calderón told CNBC.
