WASHINGTON — The Defense Department’s Office of the Inspector General announced Thursday it has opened an investigation into Secretary Pete Hegseth’s highly criticized use of the Signal messaging app to communicate about plans to bomb Yemen.

The evaluation stems from a letter the chairman and ranking member of the U.S. Senate Armed Services Committee, Republican Roger Wicker of Mississippi and Democrat Jack Reed of Rhode Island, sent last week, asking the watchdog agency to look into the matter. 

Acting Defense Department Inspector General Steven A. Stebbins wrote in a memo announcing the investigation that the Inspector General Act of 1978 “authorizes us to have access to personnel and materials as we determine necessary to perform our oversight in a timely manner.”

The purpose of the evaluation, he wrote, “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.”

The investigation will take place in Washington, D.C., as well as U.S. Central Command Headquarters in Tampa, Florida.

Concerns about the use of Signal, an encrypted messaging app available commercially, began after The Atlantic published an article detailing how its editor-in-chief, Jeffrey Goldberg, was inadvertently added to a group chat exchanging messages about national security plans. The ensuing controversy has been dubbed “Signalgate.”

Vice President J.D. Vance, Hegseth, Secretary of State Marco Rubio, Director of National Intelligence Tulsi Gabbard, CIA Director John Ratcliffe, National Security Advisor Michael Waltz and others were all in the group.

They were discussing plans for U.S. troops to bomb Houthi rebels in Yemen, which has raised significant concerns about how senior Trump administration officials are communicating and handling classified information.
