This begs the bigger question no one is asking. Why would the Former FBI Deputy Director need to ask for immunity in the first place. FBI agents and senior staff should not be breaking laws.
Exactly. People here are talking about him taking out 'bigger fish'. He was the FBI Deputy Director! He's big enough to have to take the consequences of his actions. Make him sit up there and plead the 5th 600 times in a row on camera. I suspect that even a dumbed down America will question that.
