Republican Sen. Lindsey Graham blasted Donald Trump as a "wrecking ball" candidate on Sunday, adding that the fellow presidential contender "hijacked the debate" with his incendiary comments about Mexican immigrants. "I think he's a wrecking ball for the future of the Republican Party with the Hispanic community and we need to push back," Graham said on CNN's "State of the Union." The South Carolina senator said he'd like to tighten U.S. border control on the U.S.-Mexico border, but warned the GOP would lose its "moral authority" if the party didn't reject Trump's stance.
