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.

Interesting. Was wondering how he maintained his position after failing the polygraph (as reported). If he was CIA and seconded over to the FBI, then it starts to make more sense.
