I love the last :35 seconds of the video, when Penetta essentially tells the senator to politely... shove it.
No changes. The General should have reminded the senator to know his place. If he wants control over the nation's military, he needs to either join the military or be the POTUS. Anybody other than that? "Senator, know your place. You do not, nor will you ever decide, which battles we fight or how. The US military will decide how to defend the nation and the POTUS will decide when it needs protecting. Viet Nam ended with lawyers deciding how to fight and everyone but the lawyers learned from that lesson. You have a nice day. And if you'd like... try to get me fired."
Contempt of Congress? I don't know anyone who has anything BUT contempt for Congress. Bunch of people who haven't pulled their heads out, to take a look around, in so long, I think they are stuck.
