On the eve of Pope Francis’ trip to Mexico, Presidential candidate Donald Trump came down hard on the pontiff, calling him a “very political person” who is being exploited by Mexico at America’s expense. The Pope is leaving for Mexico just after noon on Friday, where he will visit a pediatric hospital, meet with an indigenous community in the southern Chiapas region, speak to youth and workers, and celebrate Mass at the shrine of Our Lady of Guadalupe. Next Wednesday, on the final day of his trip, Francis will visit the border town of Ciudad Juárez, where he will participate in several events, including the celebration of a “cross-border” Mass. On Fox Business Network Thursday morning, Stu Varney reminded Donald Trump that the Pope is going “to stand at the border” with migrants, and asked for his take on the matter. “I think that the Pope is a very political person,” Trump responded, before adding that he thinks the Pope is being used by Mexico to advance its interests against the United States. “I think he doesn’t understand the problems our country has,” he continued. “I don’t think he understands the danger of the open border that we have with Mexico.
