PEOPLE WHO ARE PRO-CHOICE. AND AND ALL HE'S GOING TO DO IS DEPRESS THE PRO-LIFE VOTE, THE EVANGELICAL VOTE. IT'S A LOSE/LOSE FOR HIM. >> THE YOUNGEST SON OF THE LATE SENATOR JOHN McCAIN IS ENDORSING KAMALA HARRIS FOR PRESIDENT. JIMMY McCAIN SAYING THE INCIDENT LAST WEEK INVOLVING DONALD TRUMP'S CAMPAIGN STAFF AT ARLINGTON NATIONAL CEMETERY CAN CONVINCED HIM TO SWITCH AFFILIATION FROM AN INDEPENDENT TO A DEMOCRAT AND SUPPORT HARRIS THIS FALL. McCAIN, WHO RECENTLY RETURNED FROM DEPLOYMENT AT A MILITARY BASE IN JORDAN SAID TRUMP'S CAMPAIGN VIOLATED A SACRED PLACE BY TAKING PHOTOS AND VIDEO IN AN AREA WHERE THEY ARE NORMALLY PROHIBITED. >> ARLINGTON CEMETERY IS SACRED TO ALL PEOPLE WHO HAVE -- ALL PEOPLE WHO ARE MEMBERS OF THE MILITARY, ALL PEOPLE WHO HAVE SERVED IN THE UNIFORM. IT'S A SACRED AREA. THERE ARE THREE GENERATIONS OF McCAIN THAT ARE BURIED THERE. IT'S A VIOLATION, BECAUSE THESE RULES ARE SET IN PLACE. THE PEOPLE WHO ARE BURIED THERE DON'T HAVE AN OPINION. THE POINT OF ARLINGTON CEMETERY IS TO GO AND SHOW RESPECT FOR THE MEN AND WOMEN WHO HAVE GIVEN THEIR LIVES FOR THIS COUNTRY. WHEN YOU MAKE IT POLITICAL, YOU TAKE AWAY THE RESPECT OF THE PEOPLE WHO ARE THERE. >> PETER BAKER, THAT'S JIMMY McCAIN, JOHN McCAIN'S SON. WE HAD JEFFREY GOLDBERG ON YESTERDAY, TALKING ABOUT HIS NEW BOOK, WHICH POINTS TO THAT McCAIN MOMENT IN 2015 AS THE CANARY IN THE COAL MINE, AS A RED FLAG, THAT HE CRITICIZED THE HEROISM AND SERVICE OF JOHN McCAIN. MOST PEOPLE THOUGHT, THAT'S IT, ESPECIALLY INSIDE A REPUBLICAN PRIMARY. YOU DON'T DO THAT. YOU'RE DONE. AND HE WENT ON, OF COURSE, TO BECOME THE NOMINEE AND THEN THE PRESIDENT OF THE UNITED STATES. THIS IS NOT A SURPRISING MOMENT, PERHAPS, GIVEN THE WAY THAT DONALD TRUMP HAS TALKED ABOUT JOHN McCAIN AND HIS FAMILY, BUT NOTABLE NONETHELESS BECAUSE JIMMY McCAIN WHO HAS SERVED TALKED ABOUT THE OFFENSE HE SAW IN A MILITARY FAMILY, NOT JUST IN WHAT DONALD TRUMP DID LAST WEEK AT ARLINGTON OR HIS TEAM DID AT ARLINGTON LAST WEEK, BUT OVER THE LAST DECADE OR SO. >> YEAH, THERE'S A DISCONNECT BETWEEN FORMER PRESIDENT TRUMP AND THE CULTURE OF MILITARY SERVICE, RIGHT? HE TOLD JOHN KELLY, HIS SECOND CHIEF OF STAFF, WHEN THEY VISITED, JOHN KELLY'S SON'S GRAVE THAT HE DIDN'T UNDERSTAND WHAT WAS IN IT FOR SOLDIER WHO IS WENT INTO COMBAT. HE SAID TO KELLY, ACCORDING TO KELLY, ANYWAY, THAT THOSE WHO WENT TO WAR WERE SUCKERS AND LOSERS. OF COURSE, HE'S DENIED THAT, BUT PRESIDENT TRUMP DID NOT GO TO WAR. HE HAD BONE SPURS THAT WERE DIAGNOSED IN HIS FEET BY A PODIATRIST WHO WAS DOING A FAVOR TO HIS FATHER TO GET OUT OF SERVICE IN VIETNAM. SO FOR A LOT OF MILITARY PEOPLE, THERE'S SOMETHING ABOUT FORMER PRESIDENT TRUMP THAT DOESN'T UNDERSTAND THE VALUES AND VIRTUES THAT MILITARY PEOPLE FEEL. REMEMBER, HE TOLD GENERAL KELLY AT ONE POINT WHILE HE WAS PRESIDENT, HE SAYS, YOU KNOW, YOU F'ing GENERALS, I DON'T UNDERSTAND, WHY AREN'T YOU LIKE THE GERMAN GENERALS. AND KELLY SAID, WHAT YOU TALKING ABOUT? THE GERMAN GENERALS IN WORLD WAR II, YOU MEAN HITLER'S GENERALS? YEAH, THEY WERE VERY LOYAL AT THIS POINT. AND KELLY HAD TO REMIND HIM, WELL, THEY TRIED TO KILL HITLER SEVERAL TIMES. HIS IDEA OF THE MILITARY IS THAT THEY ARE POLITIC AND ANSWER TO HIM, THAT THEY ARE TO BE LOYAL SERVANTS TO HIM. THAT IS WHAT MARK MILLEY, THE JOINT CHIEFS CHAIRMAN, HE APPOINTED HIMSELF, RESISTED IN THE FINAL MONTHS OF THE ADMINISTRATION. HE WROTE A SECRET RESIGNATION LETTER, HE WAS SO UPSET AT THE WAY HE SAW TRUMP POLITICIZING THE MILITARY, HE PUT THE LETTER IN A DRAWER AND SAID, I'M GOING TO FIGHT TO KEEP TRUMP FROM ABUSING THE POWER OF THE MILITARY FOR POLITICAL PURPOSES, IN THOSE LAST DAYS IN OFFICE. OF COURSE, MIKE FLYNN SHOWS UP IN THE WHITE HOUSE WITH A PLAN THAT WOULD ESSENTIALLY DECLARE MARTIAL LAW OVER THE COUNTRY IN ORDER TO REINSTATE OR TO KEEP PRESIDENT TRUMP IN POWER. SO HIS RELATIONSHIP WITH THE MILITARY IS A FASCINATING AND IMPORTANT ONE. AND I THINK IT'S POPULAR WITH A LOT OF PEOPLE IN THE MILITARY, IF YOU DO THESE RALLIES, YOU'LL SEE A LOT OF VETERANS THERE. HE ABSOLUTELY DOES SPEAK TO THEM IN A LOT OF WAYS. BUT A LOT OF PEOPLE WHO HAVE THE FEELING AND THE CULTURE OF THE PLACE, PEOPLE LIKE JIMMY McCAIN, JOHN McCAIN AND HOW HE PASSED REALLY RESENT TRUMP'S ATTITUDE TOWARD THE MILITARY. >> JIMMY McCAIN, YOU REALLY SEE A LITTLE BIT OF JOHN McCAIN'S LEGACY LIVING ON, IF YOU LOOK AT
