The Pentagon's Inspector General has completed its long-awaited investigation into US Defense Secretary Pete Hegseth’s use of Signal to share sensitive military information earlier this year, NBC reported, citing two individuals familiar with the matter.

Hegseth received the final report on Tuesday. The findings stem from an eight-month probe into what has been dubbed Signalgate, centering on the unauthorized use of an encrypted messaging app to discuss pending military operations.

Sources expect the Inspector General report to be released publicly within days. The Pentagon has not commented on the report’s contents or timeline for publication.

Hegseth shared strike details via Signal App

The investigation focused on a Signal group chat Hegseth used in March to relay operational details related to planned United States military strikes in Yemen. Though Signal is encrypted, it is not a classified communication channel.

Hegseth has insisted he did not transmit any classified material. However, concerns grew after it emerged that some of the information he shared mirrored details sent through a secure system by Army Gen. Michael Erik Kurilla, then head of US Central Command.

NBC News previously reported that Kurilla had transmitted sensitive timing and target data about US fighter jet operations in Yemen. That information, according to officials, was later reflected in the Signal messages Hegseth shared with other Trump administration officials, and separately with family members and his personal attorney.

The group chat became public after an editor from The Atlantic was mistakenly added.

Content of the inspector general report

Sen. Roger Wicker (R-Miss.) and Sen. Jack Reed (D-R.I.), the top Republican and Democrat on the Senate Armed Services Committee, requested the investigation on March 27. They asked for a detailed assessment of what information was shared and whether any classified data had been transferred from secure systems to unsecured platforms.

They also requested a summary of “any remedial actions” taken and an evaluation of whether operational security was compromised.

While the contents of the final report remain under wraps, both lawmakers have expressed concern over the implications of military leaks during active operations.

Broader scrutiny of Pete Hegseth

The report arrives as Hegseth faces additional scrutiny related to a separate military decision involving a second strike on an alleged drug-smuggling vessel in the Caribbean Sea. The Pentagon has confirmed that the first strike left at least two survivors, while the second reportedly targeted the same vessel carrying 11 individuals.

Both Wicker and Reed have publicly raised questions about the justification and legality of the second strike. The White House has maintained that all military actions were in line with international law.

Congressional concern over military leaks

The broader issue of military leaks and information handling remains a growing concern in Washington. Lawmakers continue to push for tighter controls on the flow of sensitive data, especially across unclassified platforms.

As the Signalgate report is expected to be released in the coming days, the focus will be on whether Hegseth’s actions constituted a breach of protocol and whether any disciplinary measures are recommended.
