Watched it. What did you find noteworthy with his body language? He seemed to be staring at his hands a lot.
He did make a fist.
First, there is the fact that he brought it up at all at a signing of "immigration modernization" (MORE executive Orders)
Right before he says "I can only imagine how these families are feeling today" and after he gets fidgety looks over to his left and puts his hand on the desk as if on an imaginary something. His chair shows fidgeting, and yes he looks down a lot. Ok somber mood there. But then...
He says and starts off with "one of the things when you are uh - in a combat zone in the military". (Ok so first why bring up military combat zone?? Why not a police/Agent warrant serving process - which is what the MSM is claiming this was AGAINST CHILD PORN)
Then he continues: "Or you're uh an FBI agent - or military er - or police officer - every family uh - just - when they put that - shield on and go out in the morning - dreads the possibility of a call - receiving that phone call. and uh my heart aches for the families - i have not had an opportunity nor will i try today - to contact them but uh they put their lives on the line and its a helluva price to pay and every single day everyone of these folks get up and - by and large the vast vast majority of these men and women are decent honorable people who put themselves on the line we owe them. ((as he is fidgeting with some folded document) but the PURPOSE of my asking you here today..."
So he brings up military combat zone first - then later he says military again, accidentally (you can tell from context and vocal mannerism this was a mental accident) so military is on his mind. You don't normally bring up military in a federal agent operation. Unless perhaps some military were deputized...
