Just notice something here. 

There's no evidence that he released or leaked anything "Classified". It's known that Hegseth went on a witch hunt for "leakers". How unlikely is it that this guy wasn't falling in line, ideologically(I mean, he actually looks qualified, even though he's kind of a crap person) and they started an "investigation" just to put pressure on him later? Like I said, this is exactly how politics is handled in Authoritarian Regimes. Dollars to donuts nothing comes of this "investigation".
