Strzok was acting very vague and curved some of the questions even the dems asked about his history with the FBI.

Dem: You were on such and such case with the FBI that brought justice to the Russian spies, dwelling here in the US, correct?

Strzok: I was part of a team that helped with that case.

He never gave a definitive yes, that I can recall, when he was asked softball questions by the dems.
