But rather than apologize, Fox went on TV again, this time speaking live with Fox Business Network anchor Maria Bartiromo, and uttered the exact same phrase a second time.

“I am not going to pay for that f---ing wall,” Fox exclaimed as a shocked Bartiromo looked on. “I am not, and [Trump] should know that, and I am not going to apologize.”

Fox was Mexico’s leader from 2000 until 2006. Former Mexican President Felipe Calderón has also gone on record forcefully rejecting Trump’s claim that Mexico will pay billions of dollars to construct a wall on the U.S.-Mexican border.
