Wisconsin Gov. and Republican presidential candidate Scott Walker said Donald Trump "needs to apologize" for his comments questioning whether Sen. John McCain is a war hero.
Walker, who tried to ignore Trump's inflammatory rhetoric by leaning on the old "Reagan commandment" that discourages attacks against fellow Republicans, also had a message for the real-estate mogul's supporters.
"At a minimum, he needs to apologize," Walker said in an interview with NBC News. "I think more people need to push him. Not just candidates or elected officials, I think more people across America including some of those who, maybe up until now, have been supporters of him."
Trump said Saturday McCain is "not a war hero because he was captured. I like people that weren't captured." Under fire, Trump later acknowledged that McCain's sacrifice was heroic.
Walker was careful not to mention Trump by name but said his insulting rant against McCain went too far, "when it came to personal attack like this against the military, an American hero, I'm gonna call it like I see it."
