“I want to commend the Department of Justice and the Federal Bureau of Investigation for their swift arrest in connection with this investigation. I pledge the full support and cooperation of the Department of Defense to the DOJ’s investigation,” says Defense Secretary Austin in a statement.
“I want to underscore that every U.S. service member, DoD civilian and contractor with access to classified information has a solemn legal and moral obligation to safeguard it and to report any suspicious activity or behavior,” adds Defense Secretary Austin.
@w7voa Does this include the Commander in Chief?
@jenned @w7voa At this point, they're prolly hoping he drops dead so the issue becomes moot.
@jenned @w7voa It most certainly includes people who repeatedly refuse to hand back classified information
@SaturniusMons @w7voa Theoretically, to date. Let's see who gets indicted first!
