Celebrity Jeb Bush and John Kasich Gang Up on Donald Trump at GOP Debate: Immigrant Deportation Is a 'Silly' and Un-American Idea "It's a silly argument. It's not an adult argument," John Kasich said of Donald Trump's plan to deport 11 million undocumented immigrants By Tierney McAfee Published on November 10, 2015 11:25 PM Share Tweet Pin Email Photo: Robyn Beck/AFP/Getty; Ida Mae Astute/ABC/Getty; Noam Galai/WireImage; Larry Marano/WireImage; Daniel Acker/Bloomberg/Getty; Pat Sullivan/AP; Mandel Ngan/AFP/Getty; John Lamparski/Getty Donald Trump took his build-a-wall approach to immigration one step further at the fourth major Republican debate in Milwaukee Tuesday night when he vowed that, if elected president, he’d deport 11 million undocumented immigrants. That’s when Ohio Gov. John Kasich jumped in to rip Trump’s plan, saying, “It’s a silly argument. It’s not an adult argument. We all know you can’t pick them up and ship them back across the border.” Trump responded by taking a shot at Kasich’s state’s economic recovery: “You’re lucky in Ohio that you struck oil.” As their exchange escalated, Trump finally sniffed, “I built an unbelievable company worth billions and billions of dollars. I don’t have to hear from this man.” The comment drew boos from the crowd and Trump quickly dismissed Kasich and said the moderators should “let Jeb [Bush] speak,” as the former Florida governor had been trying to interject. Meet all the 2016 Presidential Candidates After Bush sarcastically thanked Trump for “allowing” him to speak at the debate, he rejected the billionaire businessman’s immigration plan as “not possible.” “It’s not embracing American values,” Bush said. “And it would tear communities apart and it would send a signal that we’re not the kind of country I know America is.” “They’re doing high fives in the Clinton campaign right now when they’re hearing this,” he added.
