US defense secretary under investigation by Pentagon for Signal app leaks

The Department of Defense Inspector General notified Secretary Peter Hegseth Thursday of an investigation concerning the use of the “unclassified” encrypted messaging app Signal in official discussions concerning military actions in Yemen.

A memo issued by Inspector General Steven A. Stebbins said the investigation was being opened at the request of the Chairman and a Ranking Member of the Senate Armed Services Committee, Roger Wicker and Jack Reed, respectively:

The objective of this evaluation is to determine the extent to which the Secretary of Defense and other DoD personnel complied with DoD policies and procedures for the use of a commercial messaging application for official business. Additionally, we will review compliance with classification and records retention requirements. We may revise the objective as the evaluation proceeds.
