The FBI chief says even if law enforcement finds a way to crack into iPhones, the larger encryption debate has to be resolved.

FOX's Jared Halpern has more from Washington:

As the FBI tussled with Apple over cracking into the San Bernadino shooter's iPhone, the agency got some help from what FBI director James Comey calls a marketplace of creative people:

(Comey) "Lots of folks have come to us with potential ideas. It looks like we now have one that may work out. We're optimistic and we'll see."

Comey responding to accusations the FBI rushed to federal court before exhausting every effort to get into the iPhone without a so-called backdoor from Apple.

The director says that's not the case, writing in the Wall Street Journal, "not all technical creativity resides within government."
