Former Alaska governor Sarah Palin has warned Donald Trump of "massive disappointment" if he backs down on his plan to deport undocumented immigrants.<br />Earlier in the week, Trump said his previous plans to deport the estimated 11 million immigrants living in the US illegally could be "softened."<br />"Trump didn't garner a lot of enthusiastic support by being soft on anything," Palin said on Fox News, "but by having a still spine and doing what he knows a majority of Americans want."
