American lawmakers have called on Apple CEO Tim Cook to answer a series of questions about the way it handles security glitches following privacy concerns relating to its FaceTime app.

It emerged last week that the Group FaceTime feature enabled users to eavesdrop on other users even if they had not accepted a call request. Apple has since shut down the feature and pledged to issue a software update to fix the glitch.
