Apple's CEO is revealing more about why he'll ignore a court order to work with the FBI to hack a terrorist's locked iPhone.

FOX's Tonya J. Powers has more:

Apple CEO Tim Cook tells ABC he has no plans to comply with that order to hack into the iPhone of one of the San Bernardino shooters:

(Cook) "Currently, the only way we know would be to write a piece of software that we view as sort of the software equivalent of cancer."

The feds say they're only asking for help with this one iPhone, which they think could have information related to the killings of 14 people.

This, as the New York Times reports Apple is developing new security measures that would make it impossible for the government to break into a locked iPhone.

Attorney General Loretta Lynch defended the FBI, saying Congress does not need to get involved as Apple has called for.
