"Three intelligence sources have informed Fox News that President Obama went outside the chain of command," Napolitano said. "He didn't use the NSA, he didn't use the CIA, he didn't use the FBI, and he didn't use the Department of Justice."
Instead, Napolitano said, Obama used GCHQ, a British intelligence and security organization that has 24-7 access to the NSA database.
"There's no American fingerprints on this," Napolitano said. "What happened to the guy who ordered this? Resigned three days after Donald Trump was inaugurated."
