He was slapping or poking Chris Wallace knee with his left hand. Is that what you were referring to?

"Chris Wallace knee" should read "Chris Wallace's knee".

Fingers moving too fast, I'm afraid.

No, I was talking about the index finger wagging. He does this to make a point, intimidate and so on.

Invading Wallace's private space I did not see; it surely speaks poorly for his decorum and maturity that he did so.

I have often wondered after his cardiac surgery whether he had a mild cognitive insult resulting in increased emotional lability.
