LAST NIGHT BETWEEN PRESIDENT BIDEN AND FORMER PRESIDENT TRUMP AFTER THE ASSASSINATION ATTEMPT. I WANT TO BRING IN AARON GILCHRIST WHO IS REPORTING FROM THE WHITE HOUSE. WHAT DO WE KNOW ABOUT THAT PHONE CALL? >> TOM, WE KNEW FROM PRESIDENT BIDEN WHEN HE SPOKE LAST NIGHT THAT HE HAD TRIED TO REACH FORMER PRESIDENT TRUMP. THAT WAS ABOUT 8:15 WHEN PRESIDENT BIDEN SPOKE. SOME WHERE BETWEEN THEN AND 10:30 THEY WERE ABLE TO HAVE A PHONE CALL. WHITE HOUSE OFFICIALS DESCRIBE THAT CALL TO US AS GOOD, SHORT, AND RESPECTFUL. THE PRESIDENT SAYING, WHEN DID HE SPEAK AROUND 8:15, THAT HE HAD REACHED OUT AND HAD LEARNED THAT FORMER PRESIDENT TRUMP WAS OKAY AND WAS HOPEFUL THAT HE WOULD CONTINUE TO BE OKAY AND THAT HE WOULD NOT BE SERIOUSLY, OBVIOUSLY, INJURED FROM THE SHOOTING YESTERDAY AFTERNOON. WE DO KNOW THAT PRESIDENT BIDEN SHORTLY AFTER WE LEARNED ABOUT THIS PHONE CALL HAVING HAPPENED RETURNED HERE TO WASHINGTON. HE LANDED A LITTLE AFTER 12:00 THIS MORNING BACK HERE IN D.C. HE WAS SUPPOSED TO STAY IN REHOBOTH BEACH THROUGH MONDAY, BUT OBVIOUSLY RETURNED HOME EARLY SO HE COULD ENGAGE WITH HIS LAW ENFORCEMENT TEAM, HIS NATIONAL SECURITY TEAM TO GET AN ASSESSMENT OF WHAT HAPPENED YESTERDAY IN PENNSYLVANIA. WE EXPECT THAT THE PRESIDENT IS GOING TO BE HAVING THAT MEETING AT SOME POINT THIS MORNING. SO SOMEWHERE IN THE NEXT HOUR AND A HALF OR SO THAT MEETING SHOULD HAPPEN AT THE WHITE HOUSE, TOM. >> AARON, AS WE TAKE A STEP BACK, WE'VE BEEN SO FOCUSED ABOUT THE HORRIFIC EVENTS THAT HAVE HAPPENED HERE, AS WE SHOULD BE. BUT WE CAN'T FORGET EVERYTHING THAT IS HAPPENING WITH THE CURRENT PRESIDENT, RIGHT? A PRESIDENT WHO IS RUNNING FOR RE-ELECTION, ADD VERY TOUGH DEBATE, AND HAS SINCE HAD SOME VERY TOUGH CONVERSATIONS WITH HIS OWN PARTY. HOW HAS THE EVENTS HERE CHANGED THE PRESIDENT'S SCHEDULE? BECAUSE WE KNOW HE ADD VERY BIG INTERVIEW SCHEDULED WITH OUR OWN LESTER HOLT SET FOR TOMORROW. IT'S IS BEEN ANNOUNCED HE HAS AT BIG INTERVIEW WITH B.E.T. LATER IN THE WEEK, I BELIEVE THAT'S ON WEDNESDAY. YOU HAVE TO ASSUME IN THAT DEFENDING HIS OWN CAMPAIGN THE STRATEGY MIGHT HAVE BEEN TO ATTACK HIS OPPONENT, BUT NOW DOES NOT SAMMY THE TIME OR PLACE FOR THAT. >> Reporter: YEAH, YOU'RE ABSOLUTELY RIGHT. IT SEEMS AT THIS POINT AS THOUGH ALL CAMPAIGN ACTIVITIES HAVE STOPPED. WE HAVEN'T HEARD ANYTHING FROM THE BIDEN CAMPAIGN SINCE THIS INCIDENT YESTERDAY AFTERNOON. WE'VE HEARD VERY LITTLE FROM THE TRUMP CAMPAIGN SINCE YESTERDAY AFTERNOON AS WELL. GIVEN THE SERIOUSNESS OF WHAT HAPPENED TO A CANDIDATE FOR PRESIDENT AND A FORMER PRESIDENT IN DONALD TRUMP. AND SO I THINK WE'RE STILL WAITING TO HEAR HOW AND IF THE PRESIDENT'S SCHEDULE MAY CHANGE. WE KNOW THAT THIS MEETING TODAY IS HAPPENING. A SENIOR WHITE HOUSE OFFICIAL TELLING US THAT BEYOND THAT, THE PRESIDENTS' DAY TO DAY IS FLU IDENTIFY. SO DOES THAT MEAN WE MIGHT HEAR FROM HIM AT SOME POINT? WE'LL BE KEEPING AN EYE OUT FOR THAT. AS FAR AS HIS SCHEDULE GOING INTO THE COMING WEEK, WE KNOW THAT THERE WERE EVENTS PLANNED. THE PRESIDENT IS SUPPOSED TO SPEAK TOMORROW IN TEXAS. I'M SUPPOSED TO BE TRAVELING THIS AFTERNOON FOR THAT ENGAGEMENT AT A CIVIL RIGHTS ANNIVERSARY, THE ANNIVERSARY OF THE CIVIL ROIST ACT, AND THEN HE WAS TO TRAVEL ON TO NEVADA TO SPEAK TO TWO EVENTS IN LAS VEGAS LATER IN THE WEEK. OF COURSE YOU MENTIONED THE INTERVIEW WITH OUR COLLEAGUE LESTER HOLT AS WELL WAS THE FOLKS AT B.E.T. NEWS. WE'RE WAITING TO SEE IF ANY OF THAT IS GOING TO CHANGE. AT THIS POINT THE SCHEDULE IS INTACT, AND WE'LL FIND OUT WHETHER THERE'S SOME CHANGE TO WHAT HE'S GOING TO DO. THIS EVE
