If the dems take the house they will launch a hundred investigations the next day and it will then be impossible to fire Sessions without being accused of obstruction of justice. Fire Sessions now while it's clear they have zero evidence of a crime and thus can't legitimately claim the firing is obstructing justice. If the dems take the house that will NOT be possible.
It’s already not possible... thanks to scumbag Sessions going off the reservation and recusing himself in Rosenstein’s favor without telling the White House.
It’s obvious now that Sessions is part of the “insurance policy.”
