Transcript for Growing Controversy for Donald Trump as Supporter Gifts Purple Heart
Growing controversy for Donald Trump after being gifted a purple heart by a supporter. This after days of intense backlash for his ongoing criticism of the Muslim American family who lost their son, an army captain, in Iraq. Questions tonight around what it means to serve and what it means to sacrifice. It's "Your voice, your vote." Something very nice just happened to me. A man came up to me, and he handed me his purple heart. Reporter: Donald Trump campaigning to be the next commander in chief never saw combat, never served in the military. But now has a purple heart. Thanks to an avid supporter. An honor awarded to those wounded in battle. That's like big stuff. I always wanted to get the purple heart. This was much easier. Reporter: Trump's lighthearted reaction lighting up social media with Iraq war veterans like congresswoman tammy Duckworth tweeting, Donald Trump, this is how one usually looks when you are awarded the purple heart. Nothing easy about it. These comments as trump continues to double down on negative headlines over his treatment of the gold star family of captain khan, one of 14 American muslims who died serving the U.S. Since 9/11. His parents' emotional challenge to trump captivating the audience at the democratic national convention last week. Have you even read the united States constitution? I will gladly lend you my copy. You have sacrificed nothing. And no one. How would you answer that, what sacrifice have you made for your country? I think I've made a lot of sacrifices. I work very, very hard. Reporter: The political backlash calling into question trump's own lack of military experience, getting four college deferments in Vietnam, then a fifth one. I had a minor melody ferment for feet, for a bone spur of the foot, which was minor. Reporter: And Sarah Palin's own son-in-law, one of the few living medal of honor recipients from combat in Afghanistan, shaming trump with this. "If real Donald Trump wants to be the commander in chief he needs to act like one, and that can't start until he apologizes to the khans." Tonight on Fox News, still no apology from the candidate. But a partial recognition of the khan family sacrifice. Obviously -- I mean, there's no greater sacrifice than you lose a son or a daughter, and you know, in the way that this happened. And I understand that. But regardless, I was viciously attacked. We'll have more on this controversy tomorrow on "Gma."
