New tonight. Only on 12, a son of Republican icon John mccain is breaking with his father's party. He is voting for Democratic presidential nominee Kamala Harris. Jim mccain sat down this afternoon with 12 news journalist, Bram Resnick to explain his decision. Bram at Carey Base. 36 year old, Jim mccain is the most private of the mccain Children but has carried on his father's tradition of military service. Jim mccain is a combat veteran of Iraq and Afghanistan. He just returned from a deployment in the Middle East with the Arizona National Guard mccain told me the political tipping point for him came when Donald Trump's campaign violated the rules at Arlington National Cemetery by shooting video among the headstones. You know, the fact of the matter is is that the United States army has, has a rule. You don't politicize Arlington and the fact that it was, it's a violation. It's a, it's a sacred place. Three generations of mccain's are, are buried there. It would be four, but my father is buried in Annapolis. You know, it, it's, it's a sacred place to me personally. You know, it's a, it's a sacred place for all veterans. And Jim mccain told me he was casting a vote for Kamala Harris, not against Donald Trump. He views Harris as a moderate who will act in a bipartisan way to move the country forward. Coming up at six. I'll have more from my interview with mccain, including what his late father would have thought about a democrat in the family. Bram Resnick, 12 news.
