This is a separate matter - apparently he lied to Congress.
Besides the felony perjury, there is a another serious felony for not reporting the interference to justice. So, if the story is true, he if facing a lot of jail time.
But my question is why does he have sensitive and certainly secret FBI case information (work product) in his possession after his dismissal? He should be arrested immediately and all his paperwork confiscated. He should not be allowed to keep FBI case material/notes after leaving the FBI.
