As the fight between Apple and the U.S. government over encryption continues to heat up, the House Commerce Committee has invited both Apple CEO Tim Cook and FBI director James Comey to testify on the subject.

The invitation comes after a week of intense back-and-forth between Apple and the FBI concerning the Cupertino tech giant's ability to assist in unlocking an encrypted iPhone 5c used by one of the San Bernardino shooters.

Cook was quick to voice his opposition to a court order compelling Apple's assistance in the case, and Apple was later granted an extension through Feb. 23 to issue a formal response. However, the Justice Department signaled that it isn't keen to wait on Apple's response, and filed a motion to compel Apple to comply with the order earlier today.
