WASHINGTON D.C. (KABC) -- As the battle over FBI access to encrypted phone data moves to Congress, new information emerged Tuesday about what was in the San Bernardino shooter's iPhone.
The phone had been the subject of an intense legal battle between the FBI and Apple, before a third party was able to hack into the device for the government.
The FBI had been investigating an 18-minute gap in Syed Farook's whereabouts after he and his wife killed 14 people in San Bernardino on Dec. 2 before dying in a police shootout.
CNN reports that the phone showed no contact with other ISIS supporters during those 18 minutes, an important piece of information to investigators.
Congress also held a committee hearing on a proposal to require companies to help government investigators access encrypted data on personal devices.
Apple's general counsel, Bruce Sewell, argued that strong encryption is particularly important in light of breaches of information at government agencies, including the IRS.
"To suggest that the American people must choose between privacy and security is to present a false choice," Sewell told the committee.
He also noted that the Chinese government had asked Apple for its source code within the last two years, a request Apple declined.
A senior FBI official said that about 30 percent of the cell phones the agency had seized in the last six months as part of investigations had passwords and that about 13 percent of the time investigators had no ability to access information.
The Associated Press contributed to this report.
