Apple CEO Tim Cook said Wednesday that it would be "bad for America" if his company complied with the FBI's demand for help unlocking an encrypted iPhone used by one of the San Bernardino shooters.
Cook said he's prepared to take the dispute to the U.S. Supreme Court. He also said he would try to make his case directly to U.S. President Barack Obama, although he did not say when or where they would meet.

In his first interview since the controversy erupted last week, Cook told ABC News that it was a difficult decision to resist a court order directing Apple to override security features on an iPhone used by Syed Farook, one of two extremists who killed 14 people in the Southern California city in December.
"Some things are hard and some things are right, and some things are both. This is one of those things," Cook said. The interview came as both sides in the dispute are courting public support, through interviews and published statements, while also mustering legal arguments in the case.
'Bad for America'
Federal officials have said they're only asking for narrow assistance in bypassing some security features on the iPhone, which they believe may contain information related to the mass murders. Apple has argued that doing so would make other iPhones more susceptible to hacking by authorities or criminals in the future.
The Apple chief expressed sympathy for the shooting victims' families, and said his company provided engineers and technical advice to authorities investigating the case. But he said authorities are now asking the company "to write a piece of software that we view as sort of the equivalent of cancer."
The software could "expose people to incredible vulnerabilities," Cook added, arguing that smartphones contain private information about users and even their families.
"This would be bad for America," he said. "It would also set a precedent that I believe many people in America would be offended by."
Response expected by Friday
Cook disputed FBI Director James Comey's argument that the court order applies to only one phone.
"If a court can ask us to write this piece of software, think about what else they could ask us to write," Cook said. "Maybe it's an operating system for surveillance. Maybe it's the ability for law enforcement to turn on the camera. I mean, I don't know where this stops."
A Department of Justice spokeswoman did not immediately respond to requests for comment. Apple is expected to file its legal response to the judge's order by Friday.
