Republican Donald Trump’s plan to deport 11 million undocumented immigrants from the US has been savaged by his party rivals in a TV debate.Two others also running for the Republican presidential nomination, John Kasich and Jeb Bush, said the plan was both impractical and divisive.Mr Trump, a billionaire New Yorker who has been leading in the polls, was booed as he tried to counter-attack.Another source of friction at the debate in Milwaukee was foreign policy.The eight candidates were divided on whether the US should do more to intervene in the Middle East, especially in the fight against Islamic State militants.But immigration sparked the biggest confrontation, when Mr Trump said a wall should be built at the US-Mexico border and all migrants living illegally in the US must be deported.This was met with disdain by Mr Kasich, the governor of Ohio.”Come on, folks, we all know you can’t pick them up and ship them back across the border. It’s a silly argument. It’s not an adult argument.”Mr Bush, the former Florida governor, said it would tear families apart and played into the hands of Democratic frontrunner Hillary Clinton.The debate, hosted by Fox Business, began by talking about minimum wage, which several candidates opposed.
Florida Senator Marco Rubio said vocational education was instead a better way to unlock American potential.”Welders make more money than philosophers. We need more welders and less philosophers.”At one point, Mr Rubio and Kentucky Senator Rand Paul tangled over the issue of military spending, with Mr Paul saying his rival’s plan to increase military spending went against conservative principles.”We can’t even have an economy if we’re not safe,” responded Mr Rubio.The primary elections, in which the Republican party and the Democratic party pick their presidential nominees, begin in February in the state of Iowa.And the nation will go to the polls in November to finally pick its new president.
