>> Brian: NEW BODY CAM FOOTAGE AFTER SECRET SERVICE KILLED THE GUNMAN AT TRUMP'S RALLY. AGENTS WERE WARNED BEFORE THE ASSASSINATION ATTEMPT. LISTEN. >> YES, SNIPER SENT THE PICTURE OUT, THIS IS HIM. >> THAT IS SNIPER THAT SENT THE PICTURE, SEEN THE BIKE AND LOST SIGHT OF HIM. >> I DON'T KNOW IF YOU GOT WHAT I DID. >> I GOT THAT. >> THIS IS HIS BIKE WITH THE STUFF AND OUR SNIPER SEEN HIM WALKING AWAY, I BELIEVE. HE WOULD BE RIGHT INSIDE THE WINDOW, SEEN THIS AND SENT THE PICTURES. >> Brian: THE SNIPER I GUESS WAS SECRET SERVICE. WRAY WILL APPEAR TODAY. YOU HAVE MARCO RUBIO. WE HAVE THIS FOOTAGE AND WILL GET MORE. WHAT DOES THIS TELL YOU? >> IT IS MASSIVE FAILURE. A SNIPER FROM A ROOFTOP IS KNOWN ULVERABILITY IN GENERAL. I THINK IT IS A KNOWN VULNERABILITY AT OUTSIDE RALLIES VM PROBLEM IS, IF YOU ARE NOT PROVIDING PERSONNEL, THEY OUTSOURCE PERIMETER. I THINK IT IS STUNNING THAT IN AN EVENT LIKE THIS, MAJOR LEADING REPUBLICAN -- REPUBLICAN NOMINEE NOW, FORMER PRESIDENT AND SOMEONE WE KNOW IS BEING TARGETED BY A FOREIGN GOVERNMENT, IT IS AMAZING. THEY WERE TAKING PICTURES ON CELL PHONE AND DISTRIBUTING IT TO A TEXT MESSAGING GROUP. INSTEAD OF REALTIME, MASSIVE SYSTEMIC FAILURE AND WE ARE LUCKY THE PERSON WAS NOT PROFESSIONALLY TRAINED, WE WOULD HAVE HAD MORE TRAGIC OUTCOME. >> Brian: DO YOU THINK THIS IS A ONE OFF? DO YOU SENSE IF WE LOOK AT OTHER TRUMP RALLIES, WE MIGHT SEE THE SAME HOLES IN SECURITY? >> I THINK WE WOULD SEE THE SAME HOLES. THIS PARTICULAR EVENT, I DON'T THINK IS A ONE OFF. REQUIRES ADDITIONAL PERSONNEL. I DON'T THINK LEVEL OF SECURITY WAS MATCHED. THIS IS BIG SYSTEMIC FAILURE AND SOMEONE NEEDS TO BE HELD RESPONSIBLE AND IT CAN NEVER HAPPEN AGAIN. >> Brian: MASSIVE NEWS, JOE BIDEN IS SET TO STEP DOWN, WILL MAKE IT OFFICIAL TONIGHT AND IT WILL BE KAMALA HARRIS WHO HAD TWO BIG SPEECHES, ONE GOT 3000 PEOPLE. DO YOU HAVE A SENSE OF YOUR FORMER COLLEAGUE IN SENATE, WHAT A HARRIS PRESIDENCY WOULD LOOK LIKE? JO >> JOE BIDEN WAS A RENTAL, HE GOT IN OFFICE AND DID NOT KNOW WHAT WAS GOING ON AND GAVE LEFTISTS RUNWAY. SHE IS NOT A RENTAL, SHE IS OWNED BY THE LEFT WING PARTY. TALK ABOUT DEFENDING ICE, DEFUNDING THE POLICE. THESE ARE THINGS SHE FOUGHT FOR, STOOD FOR AND VOTED FOR AS SENATOR AND THAT IS WHAT SHE WILL DO AS PRESIDENT. SHE IS A LEFT WING DEMOCRAT AND WILL BE MOST RADICALLY LEFT PRESIDENT THIS COUNTRY HAS EVER HAD. SHE WILL BE WORSE THAN BIDEN, SHE FULLY BELIEVES THESE THINGS AND WILL MAKE THEM PRIORITIES. BIDEN HAD NO POLITICAL BASE, SHE BELIEVES IN THESE THINGS AND WILL PUSH THEM AND THIS COUNTRY WILL BE DESTROYED. >> Brian: DO YOU THINK PRESIDENT TRUMP HAS A GAME PLAN FOR THIS? >> I'M SURE. IT WAS WIDELY SPECULATED. I WOULD EXPECT SHE WANTED THE ADMINISTRATION TO GO FURTHER. HER REACTION TO ISRAEL AND FIGHT AGAINST HAMAS WOULD BE MORE PALATABLE TO HAMAS COSTUME PEOPLE THAN WHAT JOE BIDEN DID. SHE BELIEVES THESE THINGS AND I THINK SHE WILL HIDE IT DURING THE CAMPAIGN AND MEDIA WILL DO EVERYTHING TO BOOST HER. SHE'S A RADICAL CALIFORNIA LEFT WINGER. >> Brian: WE HAVE PRIME MINISTER NETANYAHU OF
