The Pentagon inspector general has reportedly expanded an investigation into Defense Secretary Pete Hegseth’s use of the encrypted messaging app Signal. Citing a congressional aide and a source familiar with the inquiry, The Wall Street Journal reported Thursday that acting Inspector General Steven Stebbins plans to widen his investigation to include a second Signal chat Hegseth made that included his wife, brother, and personal lawyer. Stebbins initially announced the launch of the investigation last month, and stated it would examine a Signal group chat Hegseth and other top officials were a part of. That chat became public after then-National Security Adviser Mike Waltz accidentally added Jeffrey Goldberg, the editor-in-chief of The Atlantic. The inquiry will now include a probe into the second group chat as well, and could pose trouble for Hegseth—who has repeatedly denied ever using the app to send classified information. Crediting their source, WSJ adds that Stebbins is concerned in part about “who took information from a government system for highly-classified information and put it into Hegseth’s commercial Signal app.”
