Pentagon investigators are looking for whether the Secretary of the Department of Defense Pete Hegseth personally wrote a text message that detailed the military plan to attack the Houthi target in Yemen or whether other staff typed in the details, according to two people who were familiar with the ongoing investigation.
The Department of Defense Department’s Inspector General Office has spent several weeks interviewing Hegseth staff members today and the former to find out how the details of the United States attack the details taken from a secret system closed in the commercial messaging application known as Signal.
“Because this is one of the ongoing DOD IG projects, in accordance with our policy, we do not provide scope or details to protect the integrity of the process and avoid evaluation compromise,” spokesman Dod IG Mollie Halperin told ABC News.

The details are delivered in two chat groups including Hegseth – one with Vice President JD Vance and other high -ranking officials, and the second includes Hegseth’s wife, who was not employed by the government.
It is still unclear how quickly the findings will be released. Hegseth is scheduled to testify for the first time as defense secretary on Tuesday, where Democratic MPs are expected to question their handling of confidential and sensitive information.
Sharing the details reported occurred around the same time in mid -March when the key member of the National Security Council President Donald Trump, including Hegseth, accidentally shared details about the March 15 missile strikes in Yemen with the Atlantic Editor in Chief.
Many of the same content are distributed in second encrypted chat with family members and others – Hegseth’s conversation groups on his personal telephone during the confirmation process including his wife, Jennifer Hegseth, the two officials told ABC News.
In addition to seeing whether the information was classified and who wrote it, the investigators also asked whether there were staff members who were asked by Hegseth or others to delete messages, according to one person who was familiar with the IG investigation.
The government is required to be based on law to maintain federal communication as an official record.
