“I expect to be informed immediately if this effort results in information identifying a party responsible for an unauthorized disclosure, and that such information will be referred to the appropriate criminal law enforcement entity for criminal prosecution,” Kasper said.

The investigations also come just weeks after Hegseth came under fire for sharing sensitive military operation details in a Signal group chat with other national security officials, which had accidentally included a reporter. The officials on the chat, inclduing Hegseth and national security adviser Mike Waltz, and President Donald Trump sought to downplay the information that was shared in the chat, though defense officials told CNN the information Hegseth shared was highly classified in order to protect service members involved.

“It is safe to say that anybody in uniform would be court martialed for this,” one defense official previously told CNN. “We don’t provide that level of information on unclassified systems, in order to protect the lives and safety of the servicemembers carrying out these strikes. If we did, it would be wholly irresponsible. My most junior analysts know not to do this.”
