DOD chief’s use of Signal app to be investigated

Use of the Signal messaging app is being investigated at the Pentagon. The Defense Department’s acting inspector general announced he will review Secretary Pete Hegseth’s use of Signal to convey plans for a recent military strike in Yemen. The review will also look at other defense officials’ use of the publicly available encrypted app, which is not able to handle classified material and is not part of the Pentagon’s secure communications network. Hegseth’s use of the app came to light when a journalist was added to a text chain by the president’s national security adviser.
