FOUR NEWS AT SIX STARTS NOW. >> SOME CAMPAIGN CONTROVERSY. THE GOVERNOR OF MICHIGAN SAYS THE NATIONAL PRESS IS FULL OF SOMETHING TONIGHT. WHAT IS FUELING THOSE FIGHTING WORDS? YES, THAT'S A REAL TWEET. THE INTENSE RESPONSE COMING AFTER A STORY IN POLITICO DROPPED WITH A FORCE OF A BOMB, CLAIMING WHITMER TOLD THE BIDEN CAMPAIGN MICHIGAN IS NO LONGER WINNABLE FOR THEM FOLLOWING LAST WEEK'S DETE. GLAD YOU'RE WITH US AT SIX. >> I'M DEVIN SCALIA AND I'M KIMBERLY GILL, OUR MARA MACDONALD IS LIVE IN NEW CENTER. MARA, THE GOVERNOR IMMEDIATELY FIRED BACK. >> YOU KNOW WHAT, KIMBERLY? I'VE DONE A LOT OF STORIES OVER THE YEARS ABOUT POLITICIANS DISAVOWING WHAT THEY HAVE SUPPOSEDLY SAID OR WHAT SHOWED UP IN SOME SORT OF PAPER OR ON TV, BUT NEVER HAVE I EVER SEEN ONE WHO ESSENTIALLY SAID THAT A WELL, THEY DID SAY THAT A NATIONAL OUTLET WAS FULL OF, WELL, YOU KNOW, I'LL TELL YOU THIS IN TALKING TO GOVERNOR WHITMER'S AIDES THIS MORNING, THEY SAY THAT THIS IS JUST NOT TRUE. POLITICO, HOWEVER, IS STANDING BY. ITS REPORTING, AND HE DID NOTHING ABOUT IT RECENTLY WHEN HE WAS PRESIDENT. PRESIDENT BIDEN'S DEBATE PERFORMANCE HAS BEEN ALL THE DEMOCRATS ARE TALKING ABOUT, ALONG WITH POTENTIAL REPLACEMENTS ON THE TICKET, CHIEF AMONG THEM GRETCHEN WHITMER AND CALIFORNIA GOVERNOR GAVIN NEWSOM, HAS THE ROAD TO THE WHITE HOUSE, GOES THROUGH THE GREAT STATE OF MICHIGAN, POLITICO IS REPORTING WHITMER CALLED THE BIDEN CAMPAIGN TO SAY SHE HATED HOW HER NAME WAS BEING FLOATED. BUT THEN THE REAL KICKER HERE, A SOURCE CLAIMING WHITMER TOLD THE CAMPAIGN MICHIGAN WAS NO LONGER WINNABLE FOR THE PRESIDENT IN LIGHT OF HIS DEBATE PERFORMANCE. >> I THINK THERE IS MORE MANURE IN THAT STORY THAN YOU'D FIND ON MACKINAC ISLAND. >> AND WHY DOES HE FEEL SO STRONGLY? BECAUSE SHE KNOWS HOW POLLING ROLLS. >> SHE IS A SEASONED PROFESSIONAL WHO BELIEVES AND FOLLOWS GOOD. DONE. YOU DON'T HAVE GOOD POLLING IN ONE DAY. SHE WOULD NEVER MAKE THAT ASSESSMENT IN 24 HOURS WITHOUT HAVING SOLID POLLING IN FRONT OF HER. NOT ONLY SHE PROBABLY WOULD NEVER MAKE THAT ASSESSMENT, PERIOD, BECAUSE MICHIGAN IS SUCH A CLOSE STATE. THE GOVERNOR, FOR HER PART, ASIDE FROM HER COLORFUL TWEET, HAS THIS TO SAY NOT ONLY DO I BELIEVE JOE CAN WIN MICHIGAN, I KNOW HE CAN BECAUSE HE'S GOT THE RECEIPTS, HE'S LOWERED HEALTH CARE COSTS, BROUGHT BACK MANUFACTURING JOBS, AND HE'S COMMITTED TO RESTORING THE REPRODUCTIVE FREEDOM WOMEN LOST UNDER DONALD TRUMP. >> BACK HERE LIVE WHEN I WAS TALKING TO RICHARD TONIGHT, I SAID, DO YOU THINK THIS IS SOME SORT OF PALACE INTRIGUE THING? AND HE SAID TO ME THAT HE THINKS IT REALLY SHOWS HOW PROMINENT GOVERNOR WHITMER HAS BECOME IN DEMOCRATIC CIRCLES, ESPECIALLY NATIONALLY, AND HOW MUCH OF A FUTURE SHE HAS ON THE NATIONAL STAGE. AND WHEN YOU GET TO THAT LEVEL, THE KNIVES COME OUT. WE'RE LIVE IN THE NEWS CENTER TONIGHT
