ALWAYS FANTASTIC REPORTING. APPRECIATE IT, THANK YOU. THE STORY TODAY AS WELL, A NEW REPORT IS LINKING RUSSIA TO THE MYSTERIOUS HAVANA SYNDROME PLAGUING HUNDREDS OF U.S. OFFICIALS AROUND THE GLOBE SINCE 2016. THIS CONTRADICTS WHAT UNITED STATES INTELLIGENCE AGENCIES SAID LAST YEAR, IT WAS UNLIKELY A FOREIGN ADVERSARY WAS RESPONSIBLE. THE KREMLIN DENIES THIS REPORT. BUT THE INVESTIGATION CITES SPECIFIC EVIDENCE NOW POINTING TO A RUSSIAN MILITARY ASSASSINATION UNIT. CHIEF NATIONAL SECURITY CORRESPONDENT JENNIFER GRIFFIN IS AT THE PENTAGON. YOU AND I COULD TALK ABOUT A HOST OF THINGS. LET'S STICK ON THIS TODAY AND YOU HAVE TO COME BACK. THE WORLD IS ON FIRE IN PARTS OF THE MIDDLE EAST. GO. >> THANK YOU, HARRIS, THIS IS AN EXPLOSIVE NEW REPORT BY 60 MINUTES, THE INSIDER THAT FOUND NEW EVIDENCE AND LINKS THAT SUGGEST THE U.S. GOVERNMENT OFFICIALS WERE ATTACKED BY A FOREIGN ADVERSARY USING A WEAPON THAT MAY HAVE BEEN USED AS A LISTENING DEVICE. THIS CAR CHASE NEAR KEY WEST FOUR YEARS AGO REVEALS RUSSIA COULD BE BEHIND THE MYSTERIOUS TRAUMATIC BRAIN INJURIES KNOWN AS HAVANA SIN DRONE. THERE WERE HANDWRITTEN NOTES OF BANK ACCOUNTS, DEVICE THAT ERASE THE CAR'S COMPUTER DATA AND THE RUSSIAN PASSPORT OF THE DRIVER. 60 MINUTES SAYS LINKS USE OF A DIRECTED ENERGY WEAPON TO THE RUSSIA MILITARY INTELLIGENCE UNIT 2155. >> IT WAS A HIGH-PITCHED METALLIC NOISE. IT KNOCKED ME FORWARD. I IMMEDIATELY FELT PRESSURE AND PAIN STARTED COURSING FROM INSIDE MY RIGHT EAR, DOWN MY JAW, NECK AND INTO MY CHEST. >> WE SPOKE TO PATIENT 0 WHO GOES BY ADAM. HE WAS WORKING UNDERCOVER IN HAVANA IN 2016 WHEN HE EXPERIENCED CRIPPLING AUDITORY SENSATION LEFT HIM UNABLE TO WALK OR MOVE. 60 MINUTES SUGGESTS THE FIRST VICTIM MAY HAVE BEEN IN FRANKFURT, GERMANY, TWO YEARS EARLIER. >> THEY PULLED OUT RECEIPTS FROM THE GR29155 GROUP THAT OUTLINES IT'S A WEAPONS PROGRAM. ONE OF THE BIG SURPRISES TO ME ASIDE FROM FRANKFURT WAS THE TRANSFER OF WEAPON TECHNOLOGY BETWEEN RUSSIA AND HANOI. >> NEW EVIDENCE IN PARTICULAR WAS INFORMATION IDENTIFYING SPECIFIC RUSSIAN INDIVIDUALS, SOME OF WHOM GOT CAPTURED BY LOCAL LAW ENFORCEMENT IN THE UNITED STATES BUT ALSO GEO TECHNICAL INFORMATION OF SHOWING THAT CERTAIN RUSSIANS WERE IN THE EXACT VICINITY OF ATTACKS IN PARTICULAR COUNTRIES AROUND THE WORLD. >> WE REACHED OUT TO THE OFFICE OF THE DIRECTOR OF NATIONAL INTELLIGENCE AND C.I.A. AND THEY STAND BY LAST YEAR'S ASSESSMENT THAT RULED OUT ANY EVIDENCE OF FOREIGN INVOLVEMENT IN THE HUNDREDS OF ATTACKS ADDING THESE FINDINGS DO NOT CALL INTO QUESTION THE VERY REAL EXPERIENCES AND SYMPTOMS THAT OUR COLLEAGUES AND FAMILY MEMBERS HAVE REPORTED. >> Harris: I'M GLAD YOU ARE ON IT. STAY ON IT.
