SHE WILL BE PRESIDENT OF THE UNITED STATES. >> SENATOR GREG, AND CRAIG GRE , THANK YOU FOR JOINING US. >> IT'S NOT EASY, IS IT? >> [ LAUGHTER ] >> THERE ARE TWO HERE WHO HAVE MODERATED DEBATES, WHICH SEEMS LIKE THE MOST THANKLESS JOB IN AMERICA, BUT WE HAVE KRISTEN WELKER HERE, HALLIE HAS DONE SOME PRIMARY-- LESTER, FIRST OF ALL, WITHOUT TRIGGERING YOU, WHAT DO YOU REMEMBER ABOUT DOING THE DEBATE IN 2016? >> I REMEMBER HOW LONELY IT FELT. WE, WHEN BOTH OF US DID IT IT WAS UNDER THE AUSPICES OF THE DEBATE COMMISSION. YOU WERE SOLO OUT THERE, YOUR BACK IS TO THIS GIANT ROOM FULL OF PEOPLE, AND THERE WERE ESTIMATES OF 100 MILLION PEOPLE WATCHING. AT THE SAME TIME IT'S SUCH A PRIVILEGE TO DO THINGS LIKE THIS, BUT YOU'RE GETTING PEOPLE LEADING UP TO IT, OR WILL HE FACT CHECK-- PEOPLE ARE TALKING ABOUT WHAT YOU ARE DOING OR THINKING. I THINK OF DAVID AND LINDSEY TONIGHT. IT'S NOT AN EASY TASK. >> IT'S DEFINITELY NOT. WHEN YOU TALK ABOUT FEELING LONELY, THERE'S NO ONE IN YOUR EAR GIVING YOU EDITORIAL BACKUP. I THINK THERE'S NO GREATER WEIGHT THAN THE MOMENTS HEADING INTO A GENERAL ELECTION DEBATE, BECAUSE YOU'RE ASKING QUESTIONS ON BEHALF OF THE PEOPLE WHO KATE WAS JUST INTERVIEWING, ON BEHALF OF THE AMERICAN PEOPLE. SO YOU WANT THE QUESTIONS TO BE UNDERSTANDABLE, NOT COMING FROM WASHINGTON IN POLITICS, BUT FROM A PLACE OF PEOPLE'S DINING ROOM TABLES. THE BEST THING YOU COULD SAY ABOUT A MODERATOR IS THAT YOU DON'T REMEMBER THE MODERATOR. >> I WAS GOING TO SAY-- BEES CAN MAKE A CAREER, THEY CAN BREAK A CAREER, THESE SITUATIONS. I CAN THINK OF A MODERATOR WHO GOT IN TROUBLE FOR FACT CHECKING, IT'S SORT OF DARNED IF YOU DO, DARNED IF YOU DO. >> ASK FOLLOW-UPS AND MAKE SURE YOU GET ANSWERS TO THE QUESTIONS. >> IT IS ALSO A QUESTION FOR THE CANDIDATES, AND HOW MUCH TONIGHT, AS WE ARE ABOUT 11 MINUTES OUT NOW, HOW MUCH WILL VICE PRESIDENT HARRIS FACT CHECK FORMER PRESIDENT TRUMP AND VICE VERSA? WE KNOW FROM PAST DEBATES THE FORMER PRESIDENT SAYS THINGS THAT AREN'T TRUE. SHE'S GOT TO PICK HER MOMENTS IN THAT SPACE OR IT WILL TAKE TIME. FORMER PRESIDENT TRUMP ALREADY, HIS CAMPAIGN, HIS TEAM, KIND OF WORKING PREEMPTIVELY GOING AFTER THE MODERATORS-- >> I WAS JUST GOING TO SAY IT'S NOT TERRIBLY RECENT, BUT I REMEMBER IN THE LAST 10 OR 15 YEARS IT HAS BECOME MORE COMMON TO ATTACK THE MODERATOR. YOU WOULD NEVER SEE CANDIDATES GO AFTER THE MODERATOR. NEWT GINGRICH JOINED IN A REPUBLICAN PRIMARY I THINK IN 2016 OR SOMETHING, AND THAT WAS DIFFERENT. >> IT TOOK ME SEVERAL MINUTES TO GET A FEEL OF THE ROOM AND GET THE TEMPERATURE OF THE CANDIDATES. HAVING DONE A LOT OF DEBATES INCLUDING THE PRESIDENTIAL DEBATE, I SWORE A LONG TIME AGO I WOULD NEVER PUBLICLY JUDGE A MODERATOR. MY HAT IS OFF TO ANYONE WHO DOES IT. >> AND YOU TRY TO TUNE OUT ANY CRITICISM YOU MIGHT BE GETTING HEADED INTO THE BIG NIGHT. >> YOU KNOW THEY ARE FEELING IT IN THEIR STOMACHS GOING INTO THIS. >> I'M FEELING IT, TOO.
