exclusive John McCain's son decries Trump appearance at Arlington as a violation that turns Cemetery into campaign backdrop when former president Donald Trump held a campaign event at Arlington National Cemetery last week first lieutenant Jimmy McCain says he viewed it as a violation the youngest son of the late Senator John McCain had already been moving away from the Republican party just weeks ago he changed his voter registration to Democrat and plans to vote for kamla Harris in November he told CNN in an exclusive interview this week but he is speaking out now for the first time about Trump because of the former president's conduct at the Hallowed Ground where several generations of McCain's family including his grandfather and great-grandfather are buried it just blows me away McCain who has served in the military for 17 years told CNN these men and women that are laying in the ground there have no choice of whether to be a backdrop for a political campaign he said I just think that for anyone who's done a lot of time in their uniform they just understand that inherently that it's not about you there it's about these people who gave the ultimate sacrifice in the name of their country McCain's decision to speak out now as part of his broader shift away from the Republican party and his family's famously conservative Roots after years as a registered independent he says he registered as a Democrat several weeks ago and plans to vote for kamla Harris in November adding that he would get involved in any way I could to help her campaign dott it's a significant move for the son of a former GOP Presidential candidate an Arizona senator while other members of the McCain family have distanced themselves from Trump including Jimmy McCain's mother Cindy who endorsed then candidate Joe Biden in 2020 and his sister Megan none except Jimmy have publicly abandoned the Republican Party despite her harsh criticisms of trump mean McCain indicated last week that she would still not endorse Harris I'm a lifelong generational conservative she tweeted Jimmy McCain who enlisted in the Marine Corps at age 17 and now serves as an intelligence officer in the 10 58th Infantry Regiment had until now deliberately sought to avoid entering the political fry Trump's attacks on his father that he was not a war hero because he was captured in Vietnam and his reported description of the Elder McCain as a loser were deeply hurtful on a personal level but not out of bounds politically Jimmy McCain believes one thing about John McCain is that he chose a public life McCain said so to attack him is really not out of the realm of his job description for the younger McCain though the Arlington episode and how the campaign has reacted to it represents a whole new level of what he perceives as Trump's disrespect for the fallen and he believes it stems from Trump's own insecurities about not having served many of these men women who served their country chose to do something greater than themselves McCain said they woke up one morning they signed on the dotted line they put their right hand up and they chose to serve their country and that's an experience that Donald Trump has not had and I think that might be something that he thinks about a lot McCain emphasized that he is speaking on his own behalf and his views do not represent those of the US Army McCain received his commission and became an officer in US Army intelligence in 2022 McCain's anger over the Arlington episode was also particularly acute because when it happened he had just returned from a 7-month deployment to a small US base on the Jordan Syria border known as Tower 22 he arrived there just weeks after three US service members were killed on the base in a drone attack by iran-backed militants and he says he thought of them when he saw Trump posing last Monday in front of gravestones it was a violation McCain said that mother that sister those families see that and it's a painful experience Trump visited the cemetery last Monday following a wreath laying ceremony honoring the 13 US military service members who were killed at Cabo Airport's Abby gate in Afghanistan in 2021 his campaign filmed the visit leading to an altercation with a cemetery staffer who attempted to prevent Trump's team from photographing and filming in the area where recent us casualties are buried according to the Army doing so violates federal law Army regulations and defense department policies Trump is not the first politician to violate a ban on political activity at Arlington in fact more than 20 years ago John McCain said he made a very bad mistake when he released a campaign at that featured a clip of him walking through the cemetery Trump in his campaign how ever have not issued such a mayaula instead according to the US Army they ignored and abruptly pushed aside a cemetery staffer who protested the activity and published footage of the event later anyway one of Trump's campaign managers Chris laivita called the Army hack and said it was 100% a manufactured story over the weekend Trump's campaign released taped statements from family members of some of the service members who were killed at AB gate who said they invited Trump to their loved ones Graves but the campaign's video of the event which they put on Tik Tok showed other gravestones too including that of an army Special Forces soldier who died by Suicide and whose family said they did not give the campaign permission to film it McCain for his part is now bracing to get more involved in this election cycle while he has been involved in veteran advocacy work for years he acknowledges that his own recent political shift has been deeply personal John McCain was my father and a lot of people lose that in the minutia McCain said he wasn't John McCain the way he is to the world he was The Man Who Loved Me and the one thing I've known about my dad since the moment I could think was that he was a good man and that he had done his part and for me to be with him towards the end of his life hearing things from Trump like he was a loser
