I haven't seen anyone else mentioning this. Did you notice how Tucker Carlson's eyes were randomly flashing emotions of alarm, confrontation, gotcha etc? And I mean random.
Seriously, if a person was conversing with me in a friendly manner, and after completing a statement his eyes suddenly went wide in alarm, his eyebrows shot upwards, and his face took on a very adversarial look (all in response to his own statement, not mine) I'd wonder if he had full control of his own face.
Watch Tucker's eyes and tell me if his expressions seem appropriate for the moment.
Tucker is an entertainment journalist--which expressively is the opposite of a Russian spy.
He was also receiving the translation after we would hear it, which would contribute to some of the apparent mis-timinga of his reactions.
The translation is moved up post production so we can hear it more naturally.

His eye expressions seemed natural to me, and in keeping with his thinking and listening hard during the whole encounter.
He definitely listens intently.
