>>> HELLO, AND THANK YOU FOR JOINING US, WE BEGIN OUR REPORT ON THE CAMPAIGN TRAIL. DONALD TRUMP AND KAMALA HARRIS TRAVELED TO BATTLEGROUND STATES THURSDAY FOR THE FIRST TIME SINCE THEIR DEBATE EARLIER THIS WEEK. FORMER PRESIDENT TRAVELED TO THE WESTERN BORDER STATE OF ARIZONA, WHILE THE VICE PRESIDENT IS FOCUSING HER ENERGY ON NORTH CAROLINA. THE STATE THAT WENT TO TRUMP THE LAST TWO ELECTIONS. TWO WON'T SEE EACH OTHER ON THE DEBATE STAGE AGAIN, IT SEEMS. THURSDAY, TRUMP PUT THE KABASH ON THAT. HARRIS GAINED ANOTHER REPUBLICAN ENDORSEMENT. FORMER ATTORNEY GENERAL UNDER PRESIDENT GEORGE W. BUSH. HE ANNOUNCED HIS SUPPORT FOR THE DEMOCRAT THURSDAY. CALLED TRUMP, QUOTE, THE MOST SERIOUS THREAT TO @ RULE OF LAW IN A GENERATION. IN THE RULE OF LAW IN GEORGIA, A JUDGE THREW OUT TWO OF THE TEN CHARGES AGAINST TRUMP IN THE FULTON COUNTY ELECTION INTERFERENCE CASE, THAT IS ON HOLD FOR THE MOMENT. THE JUDGE SAID THE CHARGES OF CONSPIRACY TO COMMIT FILING FALSE DOCUMENTS AND CONSPIRACY TO COMMIT FORGERY BELONGED IN FEDERAL COURT. CBS NEWS POLITICAL CORRESPONDENT, KAITLYN HUEY- BURNS JOINS ME FROM TUCSON, ARIZONA. SO KAITLYN, IS THAT IT FOR THE DEBATE? NO DEBATES? IT'S OVER? NO MORE? >> Reporter: WELL, JOHN, GOOD TO SEE YOU. AS YOU MAY KNOW WHEN IT COMES TO DONALD TRUMP, NEVER SAY NEVER. HE DID MAKE IT PRETTY CLEAR TODAY THROUGH A POST, STARTING OFF HIS RALLY HERE IN TUCSON, ARIZONA, BY SAYING THERE WILL NOT BE A THIRD DEBATE. AND HE ALSO TOOK TO THE STAGE HERE IN ARIZONA AND RIGHT OFF THE BAT IN THIS FIRST POST DEBATE RALLY, SPENT A SIGNIFICANT AMOUNT OF TIME CRITICIZING THE DEBATE MODERATORS, CALLING THE DEBATE RIGGED. REALLY KIND OF FEEDING INTO THE RHETORIC THAT WE SAW FROM HIS CAMPAIGN IN THE WAKE OF THAT PERFORMANCE. AND DECLARING VICTORY IN HIS WORDS, FROM THAT DEBATE. AT THE SAME TIME, ARGUING THAT HE DOESN'T WANT TO DO ANOTHER ONE. NOW, CBS NEWS HAS OFFERED ANOTHER DEBATE IN OCTOBER FOR THE TWO PRESIDENTIAL CANDIDATES. WE'LL SEE IF ANY MINDS ARE CHANGED BEFORE THEN. WE ALSO, OF COURSE, ARE HAVING A VICE PRESIDENTIAL DEBATE ON OCTOBER 1. THAT IS STILL ON THE BOOKS, OF COURSE. BUT, IT IS TELLING, JOHN, THAT FORMER PRESIDENT IS SPENDING THE TOP OF HIS SPEECH, WHICH YOU KNOW, HE'S COMING HERE TO FOCUS ON IMMIGRATION AND THE ECONOMY, BUT FOCUSING THE TOP OF THIS APPEARANCE ON CRITICIZING THE MODERATORS OF THAT DEBATE A COUPLE OF NIGHTS AGO. >> FASCINATING. ALL RIGHT, SO LET'S STAY WITH FORMER PRESIDENT TRUMP FOR THE MOMENT. WHAT IS THE SENSE, I KNOW HE JUST STARTED TALKING ABOUT HOW HE WILL SPEND THE NEXT 54 DAYS. >> Reporter: YEAH, TELLING JOHN, THAT HE CHOSE ARIZONA TO COME TO AFTER THAT DEBATE. ARIZONA, AS YOU MENTIONED, IS A KEY BATTLEGROUND STATE. A STATE THAT DONALD TRUMP LOST JUST UNDER 11 ,000 VOTES. POLLS SHOW IT'S VERY CLOSE HERE. IT'S BEEN HERE FOUR TIMES OVER THE COURSE OF THE 2024 CYCLE. AND I WAS WITH HIM COVERING HIM JUST A COUPLE OF WEEKS AGO, WHEN HE WAS HERE IN TUCSON, AND ALSO MADE A VISIT TO THE SOUTHERN BORDER. THEY ARE REALLY TRYING TO FOCUS ON THE ISSUE OF IMMIGRATION, ESPECIALLY HERE IN ARIZONA, BUT REALLY ACROSS THE BATTLEGROUND STATES, AND ALSO THE ECONOMY. A SPECIFIC PORTION OF THE ECONOMY HERE IN ARIZONA. THEY WANT TO FOCUS ON THE ISSUE OF AFFORDABLE HOUSING. WE HAVE SEEN IN OUR OWN CBS NEWS POLL A COUPLE OF MONTHS AGO IN ARIZONA, A MAJORITY, VAST MAJORITY OF VOTERS FEEL LIKE IT IS ALMOST IMPOSSIBLE TO BUY A HOUSE, MORE DIFFICULT THAN IT WAS FOR THEIR PARENTS GENERATION IN THEIR WORDS. THOSE ARE THE ISSUES THE CAMPAIGN WOULD LIKE TO FOCUS ON. AS WE SAW IN THAT DEBATE, THIS IS A CANDIDATE WHO GOES OFF SCRIPT AND DOUBLES DOWN. THOSE CONTROVERSIAL AND DEBUNKED CLAIMS THAT HE MADE ABOUT SPRINGFIELD, OHIO. JUST A FEW MINUTES AGO, HE ECHOED HERE IN REMARKS. >> DATE >> THE FINAL QUESTION FOR YOU IS ABOUT NORTH CAROLINA AND THE OTHER CAMPAIGN, THE HARRIS CAMPAIGN. DO THEY REALLY THINK IT IS IN PLAY, THIS IS THE HARDEST OF THE BATTLEGROUND STATES BY THE TRADITIONAL ASSUMPTIONS. GIVE US YOUR THOUGHTS. >> Reporter: THAT'S RIGHT, JOHN. EVER SINCE BARACK OBAMA WON IT IN 2008. DEMOCRATS HAVE BEEN TRYING TO REPEAT THAT DYNAMIC AND HAVE BEEN UNSUCCESSFUL. I INTERVIEWED DEMOCRATIC GOVERNOR, ROY MOORE, EXCUSE ME, ROY COOPER, EXCUSE ME, ROY COOPER A COUPLE NIGHTS AGO AT THE DEBATE. THE REASON HE THINKS IT IS ACTUALLY IN PLAY NOW, AS OPPOSED TO WHEN BIDEN WAS, OF ALL THE STATES THAT DONALD TRUMP WON, HE WON NORTH CAROLINA BY THE SMALLEST OF MARGINS IN 2020. SO THEY BELIEVE THE GROUND HAS BEEN FERTILE FOR THEM, ESPECIALLY WITH YOUNG VOTERS AND AFRICAN AMERICAN VOTERS. THE KEY IS HAVING A NEW CANDIDATE THAT COULD ACTIVATE THEM. IT'S A STATE WHEN YOU LOOK AT THE SOUTH, IT HAS A DEMOCRATIC GOVERNOR. THERE'S A KEY GOVERNOR'S RACE AS WELL. SO, THOSE KINDS OF RACES COULD BE TIED. IT WILL BE AN UPHILL CLIMB. AND THE HARRIS CAMPAIGN IS HOPING THAT BY SPENDING TIME THERE, THEY ALSO HOPE -- THEY WILL ALSO FORCE REPUBLICANS TO SPEND TIME AND MONEY IN THAT STATE THAT THEY SHOULD HAVE IN THEIR COLUMN. >> CAITLIN HUEY-BURNS IN
