I'm just throwing darts here, but does this at all have anything to do with him possibly being less than forthright about the spying activities against Trumps campaign by former administration? Anything to do with him NOT going hard against Clinton for obvious abuses of her email and Foundation?
One final point to consider, will the next Director now decide to reassess the free pass (in my opinion) that Clinton was given in coordination with the former AG Lynch, especially considering the last few days in which Clinton proudly announced "I am now part of the resistance".
If any of the above are true, she might want to reconsider her position on this matter...
