Attorney General William P. Barr said Tuesday the nation's leading technology companies must assist law enforcement officials investigating terrorists, drug cartels and other criminal suspects using encrypted messaging apps.

Delivering the keynote address at the International Conference on Cyber Security in New York City, Mr. Barr said encrypted and secure "consumer products and services" offered by Apple, Facebook and other tech firms threaten national security. The products include messaging, smartphones, email, and voice and data apps that prevent unauthorized scrutiny of their content.
