Really, I think Bird also said if Mattis decided to reslease troop strength that that would be Ok. But not when I ask for it. Hmm, I think that this was acceptable information prior to the Obama Administration such as it was under The Bush Administration says something to me.
Not sure why you see a problem with that. He is the sitting SECDEF and also a retired four star general. He obviously has the position and experience to determine that it is appropriate to release that information at this time.
