The five remaining Republican presidential candidates debated in Houston, Texas, Thursday night in their final showdown before Super Tuesday. Candidates Marco Rubio, Ted Cruz, John Kaisch and Ben Carson all attacked front-runner Donald Trump, who has won three out of the four primaries and caucuses to date. This comes as former Mexican President Vicente Fox spoke out in an interview with Univision and Fusion host Jorge Ramos about Trump’s repeated calls to build a wall on the U.S.-Mexico border, which Trump says he would make Mexico pay for.

Vicente Fox: “I declare, I’m not going to pay for that [blee] wall. He should pay for it. He’s got the money.”

Jorge Ramos: “Are you afraid that he’s going to be the next president of the United States? What would that mean?”

Vicente Fox: “Not at all. Not at all.”

Jorge Ramos: “What would that mean for Mexicans?”

Vicente Fox: “Not at all. Democracy cannot take us to crazy people that doesn’t know what’s going on in the world today.”
