I listened to the video several times and I am still not sure. At the part where he first interjects (ma’am according to Fox) Boxer is still talking and comes across over the General.
Yeah, it’s hard to tell but it’s evident she didn’t hear it. It would have been something if he’d repeated Ma’am after she finished talking. :)
