OF THE POWER GRID? >> ALL RIGHT, JOHN, WE APPRECIATE THE ANALYSIS, AS ALWAYS. THANK YOU. MEANWHILE, MORE CLASSIFIED DOCUMENTS HAVE BEEN FOUND AT A STORAGE UNIT USED BY FORMER PRESIDENT TRUMP. THE DISCOVERY CAME AFTER A FEDERAL JUDGE ORDERED TRUMP TO DO A MORE THOROUGH SEARCH OF HIS PROPERTIES. ABC'S SENIOR INVESTIGATIVE REPORTER AARON KATERSKY JOINS ME LIVE NOW FOR MORE ON THIS. AARON, HOW SIGNIFICANT IS THIS DISCOVERY? >> THIS IS A SIGNIFICANT DISCOVERY BECAUSE IT RAISES THE QUESTION OF WHETHER THE JUSTICE DEPARTMENT HAS RECOVERED ALL THE CLASSIFIED MATERIALS THAT TRUMP OR HIS AIDES TOOK FROM THE WHITE HOUSE AND MOVED DOWN TO FLORIDA, WHERE THIS STORAGE UNIT WAS LOCATED. A FEDERAL JUDGE IN WASHINGTON, WE'RE TOLD, HAD ORDERED TRUMP'S LAWYERS TO DO A MORE THOROUGH SEARCH FOR CLASSIFIED MATERIALS . AND SO TRUMP HIRED AN OUTSIDE FIRM TO SEARCH FOUR OF HIS PROPERTIES, THIS STORAGE UNIT BEING ONE OF THEM, HIS GOLF CLUB IN BEDMINSTER, NEW JERSEY, WHERE HE SPENDS THE SUMMERS TRUMP TOWER IN NEW YORK BEING AMONG THE OTHERS. AND THE SEARCH TURNED UP AT LEAST TWO MORE DOCUMENTS WITH CLASSIFIED MARKINGS. THE JUSTICE DEPARTMENT WAS ALERTED AND WHILE THEY DIDN'T COMMENT, THOSE TWO DOCUMENTS NOW BECOME PART OF THE CRIMINAL INVESTIGATION THAT'S BEING LED NOW BY A SPECIAL COUNSEL. >> SO WHAT'S THE RESPONSE FROM PRESIDENT, FORMER PRESIDENT TRUMP OR HIS TEAM? >> AND COULD THIS LEAD TO NOW A LARGER SEARCH? >> WELL, THE TRUMP SIDE SAYS THAT THIS IS THEM BEING COOPERATIVE, THAT THEY HAD THIS REQUEST FROM THE FEDERAL JUDGE AND THEY WANTED TO BE AS TRANSPARENT AND OPEN AND HELPFUL AS POSSIBLE TO TRY TO RECOVER ALL OF THESE DOCUMENTS. >> THEY STILL HAVE NOT ANSWERED THE QUESTION AS TO WHY THE DOCUMENTS WERE MOVED IN THE FIRST PLACE FROM THE WHITE HOUSE WHERE THEY RIGHTFULLY BELONGED, AND THEN INTO THE NATIONAL ARCHIVES DOWN TO FLORIDA. THE JUSTICE DEPARTMENT IS INVESTIGATING THAT PIECE AND WHETHER THERE WAS ANY ATTEMPT TO OBSTRUCT THAT INVESTIGATION WHEN THE NATIONAL ARCHIVES AND THEN THE FBI
