So, let's see what General Ham is made of.
Unfortunately, it seems like brass often makes soldiers soft, and turns them into bureaucrats and political actors. If Ham was indeed relieved of his command because of something related to the murders in Benghazi, and he has information that would clarify this for the American people, let's see him dare to come forward with the truth, even if it places him at personal risk of either retribution from the administration, or culpability in the failure of security in Benghazi.
He could be an American hero, if he's willing to take the risk for the sake of his sacred oath.
