FOX News' Judge Andrew Napolitano talks to Stuart Varney of the FOX Business Network about Debbie Wasserman Schultz's I.T. aide Imran Awan and his brothers who also worked for the House of Representatives. Awan, a Pakistani, was arrested attempting to leave the country last month. Napolitano said there is an allegation that the Awan and his brothers sold information they had access to which included nearly every Democratic Congressperson's computer and potentially sensitive classified material from the House Intelligence Committee. "He was arrested for some financial crime. That is the tip of the iceberg," he said. "The real allegation against him he had access to the emails of every member of Congress and he sold what he found in there. What did he sell? And to whom did he sell it? That is what the FBI wants to know. This may be a very, very serious national security investigation," Napolitano said. For a reason yet explained Awan was fired by Democratic members of Congress earlier this year except for Debbie Wasserman Schultz who kept him on. STUART VARNEY, FOX BUSINESS NETWORK: A tech worker worked for Debbie Wasserman Schultz. Reportedly liquidating real estate assets as he was arrested trying to leave the country. What do you make of this development? JUDGE ANDREW NAPOLITANO, FOX NEWS: He was arrested at the last minute by the FBI who were notified by TSA that he was on a flight to Pakistan. He was arrested for some financial crime. That is the tip of the iceberg. The real allegation against him he had access to the emails of every member of Congress and he sold what he found in there. What did he sell? And to whom did he sell it? That is what the FBI wants to know. This may be a very, very serious national security investigation. VARNEY: Wait a second. He was the I.T. worker, along with his two Pakistani brothers, for Debbie Wasserman Schultz and other Democrats in the House. NAPOLITANO: Yes. VARNEY: And the theory is he got access to all of their secrets or whatever and sold some. NAPOLITANO: Yes. And this was at the time that Congresswoman Schultz was also the chair of the Democratic National Committee. At this point, I don't believe they know what he sold and to whom he sold it but they do know what he had access to, which is virtually everything in the House of Representatives. VARNEY: Goodness me. NAPOLITANO: Which would include classified material from the House Intelligence Committee.
