The Latest: FBI chief says encryption blocks investigations

The Latest on the worldwide threat assessment from U.S. intelligence agencies (all times local):


5 p.m.

FBI Director James Comey says one of the phones used by the killers in the San Bernardino, California, attacks remains inaccessible to investigators more than two months after 14 people were fatally shot.

Comey is testifying before the Senate Intelligence Committee.

He cites the case as an example of how encryption is affecting counterterrorism efforts. But he says the dilemma of bad guys "going dark" is mostly affecting state and local law enforcement officials who are trying to solve murder, drug and car accident cases.
