Libertarian presidential candidate Gary Johnson quipped Friday that Donald Trump was probably watching the Olympics to see the Mexican pole vaulters.

"I hear that Donald Trump is watching the Olympics tonight. He's seeing how high the Mexican pole vaulters go," Johnson said in an interview with the Reno Gazette-Journal before an appearance in the state.

Trump of course, has vowed to build a wall along the Mexican border. A high one.

"Look, the deportation of 11 million undocumented workers starts with misinformation," Johnson siad of Trump's plan to deport illegal immigrants back to Mexico and Central America. "They are hardworking people that have come into the Untied States and they have to come in illegally because the government can't provide them an easy way to get in legally."
